| 2 | Late Quaternary surface deformation and rupture behavior of strong earthquake on the segment north of Mianning of the Anninghe fault显示文摘The Anninghe fault is an important active fault along the eastern boundary of Sichuan-Yunnan active tectonic block, and the study of its surface deformation and rupture behavior during strong earthquake in the late Quaternary is of fundamental importance for understanding the future seismic risk of the fault zone or even the entire western Sichuan region. Using the methods of detailed geomorphic and geological survey, digital image analysis, total station instrument survey, excavation of combined trench and dating, we analyze the geomorphologic sequences of the offset strata at several sites where the late Quaternary deformation remnants are fairly well preserved and obtain some new results as follows: Strong earthquake events with left-lateral displacements of about 3 m occurred at the two sites of Zimakua and Yejitong at 1634-1811, 1030-1050 and 280-550 a BP, respectively, and the recurrence interval is 520-660 a; The youngest event in the area of Dahaizi-Ganhaizi should be the earthquake of 1536, other events are at 1768-1826, 2755-4108 and 4108-6593 a BP, respectively, with a recurrence interval of 1300-1900 a. The strong earthquake activity shows a clustering character. The possibility of occurrence of a strong earthquake exists on the north segment of the Anninghe fault sometime in the future. | RAN YongKang CHEN LiChun CHENG JianWu GONG HuiLing | 2008 | Science China Earth Sciences2008，51，9： | 25 |
| 3 | The Lushan M_S7.0 earthquake and activity of the southern segment of the Longmenshan fault zone显示文摘Following the Lushan MS7.0 earthquake on 20 April 2013,a topic of much concern is whether events of MS7 or greater could occur again on the southern segment of the Longmenshan fault zone.In providing evidence to answer this question,this work analyzes the tectonic relationship between the Lushan event and the 2008 Wenchuan earthquake and the rupture history of the southern segment of the Longmenshan fault zone,through field investigations of active tectonics and paleoearthquake research,and our preliminary conclusions are as follows.The activity of the southern segment of the Longmenshan fault zone is much different to that of its central section,and the late Quaternary activity has propagated forward to the basin in the east.The seismogenic structure of the 2008 Wenchuan earthquake is the central-fore-range fault system,whereas that of the 2013 Lushan event is attributed to the fore-range-range-front fault system,rather than the central fault.The southern segment of the Longmenshan fault zone becomes wider towards the south with an increasing number of secondary faults,of which the individual faults exhibit much weaker surface activity.Therefore,this section is not as capable of generating a major earthquake as is the central segment.It is most likely that the 2013 earthquake fills the seismic gap around Lushan on the southern segment of the Longmenshan fault zone. | CHEN LiChun RAN YongKang WANG Hu LI YanBao MA XinQuan | 2013 | Chinese Science Bulletin2013，58，28： | 24 |
| 4 | The M_S7.1 Yushu earthquake surface rupture and large historical earthquakes on the Garzê-Yushu Fault显示文摘As revealed by field investigations,the co-seismic surface rupture zone of the 2010 MS7.1 Yushu earthquake,Qinghai is a characteristic sinistral strike-slip feature consisting of three distinct sinistral primary ruptures,with an overall strike of 310°-320° and a total length of 31 km.In addition,an approximately 2-km-long en-echelon tensile fissure zone was found east of Longbao Town;if this site is taken as the north end of the rupture zone,then the rupture had a total length of ~51 km.The surface rupture zone is composed of a series of fissures arranged in an en-echelon or alternating relationship between compressive bulges and tensile fissures,with a measured maximum horizontal displacement of 1.8 m.The surface rupture zone extends along the mapped Garzê-Yushu Fault,which implicates it as the seismogenic fault for this earthquake.Historically,a few earthquakes with a magnitude of about 7 have occurred along the fault,and additionally traces of paleoearthquakes are evident that characterize the short-period recurrence interval of large earthquakes here.Similar to the seismogenic process of the 2008 Wenchuan earthquake,the Yushu earthquake is also due to the stress accumulation and release on the block boundaries resulting from the eastward expansion of Qinghai-Tibet Plateau.However,in contrast with the Wenchuan earthquake,the Yushu earthquake had a sinistral strike-slip mechanism resulting from the uneven eastward extrusion of the Baryan Har and Sichuan-Yunnan fault blocks. | CHEN LiChun WANG Hu RAN YongKang SUN XinZhe SU GuiWu WANG Ji TAN XiBin LI ZhiMin ZHANG XiaoQing | 2010 | Chinese Science Bulletin2010，55，31： | 17 |
| 5 | History,status and trend about the research of paleoseismology显示文摘Paleoseismology was originated in the late nineteen century, but the modern paleoseismology formed at the end of the 1970s. Three stages (appearance, development and maturity) can be identified for paleoseismology in China. Great progress has been made in the aspects of trench technology, recognition signs, dating method and theoretical model, however,they are not developed to such a level at which the highly reliable data can be provided for the probability prediction of earthquakes. The main questions further concerned in the future include the study of geological evidence, chronology and displacement, the theoretical model about reliability, paleoearthquake feature in the region and large-earthquake reoccurrence, and new branches related with the paleoseismology in the stable continent region, usage of new technology and frontier sciences. | Yongkang Ran Qidong Deng | 1999 | Chinese Science Bulletin1999，44，10： | 15 |
| 6 | The maximum coseismic vertical surface displacement and surface deformation pattern accompanying the Ms 8.0 Wenchuan earthquake显示文摘The amount of coseismic deformation and its distribution of the Wenchuan earthquake provide important scientific bases for revealing the mechanisms of earthquake preparation and characterizing the rupture propagation of the Wenchuan earthquake. The previous studies have indicated that the earthquake ruptured the middle-to-north segment of the Longmenshan central fault and the middle segment of the Longmenshan range-front fault, which are characterized by two surface rupture zones of 240 km and 90 km in length, respectively. Based on the pre-earthquake information and photos of landforms and buildings obtained through ge-ologic and geomorphic survey of the area around Shaba Village of Beichuan County, Sichuan Province and the extensive interview with local villagers, we measured the displacements of the major terrain features and the dislocated buildings by total station instruments and differential GPS and obtained the maximum vertical displacement of 9±0.5 m and right-lateral displacement of 2±0.5 m around the Zou’s house in Shaba Village. Though the near-surface deformation exhibits a normal faulting around Shaba Village, the dynamic environment has not changed on the whole. The NW wall of the fault uplifted but without gravity gliding as normally occurring on the hanging wall of a normal fault, which proves that the 9±0.5 m displacement should be the maximum coseismic vertical displacement of the May 12, 2008 Ms 8.0 Wenchuan earthquake. | Ran YongKang Shi Xiang Wang Hu Chen LiChun Chen Jie Liu RuiChun Gong Huiling | 2010 | Chinese Science Bulletin2010，55，9： | 9 |
| 7 | Measurement of terrace deformation and crustal shortening of some renascent fold zones within Kalpin nappe structure显示文摘The Kalpin nappe structure is a strongest thrust and fold deformation belt in front of the Tianshan Mountains since the Cenozoic time. The tectonic deformation occurred in 5―6 striking Meso-zoic-Cenozoic fold zones, and some renascent folds formed on the recent alluvial-proluvial fans in front of the folded mountains. We used the total station to measure gully terraces along the longitudinal to-pographic profile in the renascent fold zones and collected samples from terrace deposits for age de-termination. Using the obtained formation time and shortening amount of the deformed terraces, we calculated the shortening rate of 4 renascent folds to be 0.1±0.03 mm/a, 0.12±0.04 mm/a, 0.59±0.18 mm/a, and 0.26±0.08 mm/a, respectively. The formation time of the renascent folds is some later than the major tectonic uplift event of the Qinghai-Tibet Plateau 0.14 Ma ago. It may be the long-distance effect of this tectonic event on the Tianshan piedmont fold belt. | YANG XiaoPing RAN YongKang CHENG JianWu CHEN LiChun XU XiWei | 2007 | Science China Earth Sciences2007，50，1： | 7 |

| 9 | Active blocks and strong seismic activity in North China region显示文摘The active North China block consists of three second-order blocks: Ordos, North China Plain, and East Shandong-Huanghai Sea blocks. Two active tectonic zones, the Anyang-Heze- Linyi and Tangshan-Cixian zones, exist in the active North China Plain block and have separated the active block into 3 third-order active blocks, Taihangshan, Hebei-Shandong, and Henan-Huai blocks. The 3 third-order active blocks are characterized by their entire motion and are clearly different in their Cenozoic structures and deep structures. The active boundary tectonic zones between the third-order active blocks are less than those between the first- and second-order active blocks in their movement strength, extent, and seismic activity. The density of M ≥ 6 earthquakes in the boundary zones between active blocks is higher than that within the blocks by 9-22 times in the North China region, up to one order of magnitude on average. M ≥ 7 earthquakes occurred basically in the boundary zones between active blocks. The difference is not occasional, but reflects the nature of intraplate movement and the characteristics of strong seismic activity and is the powerful evidence for hypothesis of active blocks. | HAN Zhujun (韩竹军) XU Jie (徐 杰) RAN Yongkang (冉勇康) CHEN Lichun (陈立春) YANG Xiaoping (杨晓平) | 2003 | Science China Earth Sciences2003，46，z2： | 6 |
| 10 | Recurrence characteristics of late-quaternary strong earthquakes on the major active faults along the northern border of Ordos block显示文摘Through study on trenches, analysis of recurrence characteristics and recurrence interval cluster/gap of strong earthquakes along the major active faults on the northern border of Ordos block, we found 62 paleoearthquakes that occurred in the late Quaternary, including 33 earthquakes occurring in the Holocene. The recurrence characteristics of the paleoearthquakes are different at three levels, segments, faults, and fault zones. The strong seismic sequence on the independent segments is mostly characterized by long- and short-interval recurrences, while that on the faults and in fault zone is characterized clearly by random and cluster recurrences. Results of the moving window test indicate that the probabilities of 'temporal cluster or gap', caused by random coincidence as opposed to intersegment contagion, are 64% and 70% for the Serteng piedmont fault and for the south-border fault of Wula Mountains, respectively, no clear interaction among the segments of each fault; while the probability is 26.8% for the whole fault zone, suggesting a clear interaction among the faults of this fault zone. These recurrence characteristics may imply an effect of the entire block motion on the recurrence of strong earthquakes. Moreover, the elapsed time for the Wujumeng Pass-Dongfeng Village segment of Serteng piedmont fault and the Tuzuo Banner-Wusutu and the Hohhot segments of Daqingshan piedmont fault has exceeded the average recurrence interval, hence these three segments may be the possible places for future strong earthquakes. | RAN Yongkang (冉勇康) CHEN Lichun (陈立春) YANG Xiaoping (杨晓平) HAN Zhujun (韩竹军) | 2003 | Science China Earth Sciences2003，46，z2： | 6 |
| 11 | Paleoseismic ruptures and evolution of a small triangular pull-apart basin on the Zemuhe fault显示文摘Trenching is a primary technique on paleoseismology to reveal evidence of surface deformation produced by large earthquakes.A good trenching site requires completeness of geologic recording on paleoseismic events and corresponding reliable dating from radiocarbon samples.Based on three-dimension trenching,we show a structure of a small triangular pull-apart basin at the Daqingliangzi section on the Zemuhe fault,then explore interrelation between paleoseismic surface rupturing and evolution of the pull-apart basin,and give a corresponding identification model.Sedimentary boundary of the pull-apart basin is tightly bounded by two branch faults,which produced multiple paleoseismic events with deformation of some large fissures in sequence.Strata are thinner at north of the pull-apart basin,however thicker at south.These above characteristics show that evolution of the pull-apart basin is a continuous sedimentation process accompanying extensional deformation produced by multiple paleoseismic events.Small pull-apart basins are favorable sites for trenching and paleoseismic study on active strike-slip faults. | WANG Hu RAN YongKang LI YanBao CHEN LiChun | 2013 | Science China Earth Sciences2013，56，3： | 4 |
| 12 | Model for Paleoearthquake Recurrence Along Baying Segment of the North Margin Fault of Fanshan Basin in Hebei Province显示文摘Based on the measurement of faulted geomorphic surfaces,large trench logging and systematic chronostratigraphic sampling,we suggest that the total slip amount along the Baying segment of the north margin fault of Fanshan Basin since 90 ka B.P.is 34 m.Nine paleoseismic events occurred in the last 75 ka.Among them,the four events A,B,C,and D revealed by the large trench were dated at 28 ka,14 ka,7.5 ka,and 656 B.P.,respectiv eJy.The model for paleoearthquake recurrence along the segment may have two stages; in the stage from 90 ka to 14 ka B.P.,the 'time-predictable model' is suitable,while in the stage from 14 ka B.P.to now,the 'displacement-attenuation model' applies. | Ran Yongkang,Fang Zhongjing,Duan Ruitao,Li Zhiyi,Wang Jingbo,Yang Zhe,Ji Fengju,and Li JianpingInsatute of Geology,State Seismologlcal Bureau,Beijing 100029,China | 1996 | Earthquake Research in China1996，10，1： | 3 |
| 13 | History of Paleoseismic ActivityAlong the Hohhot Segment of Daqingshan Piedmont Fault in the Late Quaternary显示文摘A detailed study on geomorphic surfaces and a set of trenches on the Hohhot segment of Daqingshan piedmont fault at three sites, Kuisu, Ulan Blang, and Qingshan Grassland, revealed 7 paleoseismic events occurred along the fault segment since 19 ka BP. Those events occurred at 18.75±.75 ka, 16.97 ±.96 ka, 14.65±.67 ka, 11.82±.69 ka, 9.45±.26 ka, 6. 83±.26 ka, and 4. 50 ±0. 23 ka BP, respectively, and their average recurrence interval is 2375±432 years. From the results of constraining fault displacement and correlation between the sediments in these trenches, we found a complete paleoseismic activity history along the fault segment during this period of time. | Ran Yongkang and Zhang PeizhenInstitute of Geology, China Seismological Bureau, Beijing 100029, ChinaHu Bo and Guo WenshengSeismological Bureau of Nei Mongol Autonomous Region,Hohhot 010000, China | 2001 | Earthquake Research in China2001，15，2： | 2 |
| 14 | Paleoseismological Study of the Late Quaternary Slip-rate along the South Barkol Basin Fault and Its Tectonic Implications,Eastern Tian Shan,Xinjiang显示文摘The easternmost Tian Shan lies in eastern Xinjiang, Central Asia. The South Barkol basin fault(SBF) in the northern part of the easternmost Tian Shan is a major tectonic structure in this orogenic region. The late Quaternary activity, paleoseismology, and deformation characteristics of the fault provide important clues for understanding the tectonic process of the eastern Tian Shan orogen and implementing seismic mitigation. Through interpretation of high-resolution satellite images, unmanned aerial vehicle measurements, and detailed geological and geomorphic investigations, we suggest that the fault exhibits clear left-lateral slip along its western segment. Paleoseismic trenches dug near Xiongkuer reveal evidence of six large paleoearthquakes. The four latest paleoearthquakes were dated: the oldest event occurred at 4663 BC–3839 BC. Data on the horizontal offsets along the probable 1842 Barkol earthquake coseismic rupture suggest clear multiple relationships between cumulative offsets and possible ~4 m of coseismic left-lateral slip per event. From the cumulative offsets and 14 C sample ages, we suggest an average Holocene left-lateral slip rate of 2.4–2.8 mm/a on the SBF, accounting for ~80% of lateral deformation within the entire eastern Tian Shan fault system. This result is comparable with the shortening rate of 2–4 mm/a in the whole eastern Tian Shan, indicating an equal role of strike-slip tectonics and compressional tectonics in this orogen, and that the SBF may accommodate substantial lateral tectonic deformation. | WU Fuyao RAN Yongkang XU Liangxin CAO Jun LI An | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 1 |

| 16 | Stimuli responsive co-delivery of celecoxib and BMP2 from micro-scaffold for periodontal disease treatment显示文摘Controlling inflammation meanwhile facilitating tissue regeneration has been considered as a promising strategy to treat inflammatory bone defect. Herein, we describe the synthesis of a bio-sensitive poly(lactic-co-glycolic acid)/mesoporous silica nanocarriers core-shell porous microsphere(PLGA/MSNsPMS) encapsulated poly(L-lactic acid)(PLLA) spongy nanofibrous micro-scaffold as a new generation of therapeutic platform for effective reconstruction of bone defects caused by periodontal diseases.The PLGA/MSNs-PMS were designed as stimuli-responsive carriers for on-demand co-delivery of multiple biomolecules to provide proper physiological environment, while the multi-level(from macro-,micro-to nanometers) nanofibrous and porous structures in PLLA micro-scaffold were in charge of the reconstruction of ECM, which synergistically contribute to the enhancement of new tissue formation under inflammatory condition. After local injection into periodontal tissue, this construct could sequentially release bone growth factor(BMP-2) as well as anti-inflammatory drug(celecoxib) loaded MSNs in response to the over-expressed matrix metalloproteinases(MMP) in periodontal region. During alveolar bone regeneration induced by BMP-2 and ECM like structure, the MSNs would further deliver celecoxib in target cells to achieve inflammation inhibition, resulting in effective treatment of periodontal disease. | Yi Hao Ran Tian Kaige Lv Zhongning Liu Jing Ni Pingyun Yuan Yongkang Bai Xin Chen | 2021 | Journal of Materials Science & Technology2021，，16： | 1 |
| 17 | Active Tectonic Research for Seismic Safety Evaluation of Long-Line Engineering Sites in China显示文摘Long-line engineering sites usually have to pass through active tectonics, so the research of active tectonics is of great importance to seismic safety evaluation of this sort of site. In the paper, basing on the summarization and analysis of the requirements for seismic safety evaluation of long-line engineering site and the status quo of active tectonics research, we propose the focal points of active tectonics research for seismic safety evaluation of long-line engineering sites, including the research contents, technical targets and routes, and the submission of the achievements, etc. Finally, we make a preliminary analysis and discussion about the problems existing in the present-day active tectonics research for seismic safety evaluation of long-line engineering sites. | Ran Yongkang Chen Lichun | 2005 | Earthquake Research in China2005，19，3： | 0 |
| 18 | Deformation Patterns and Shortening Rates in the East Part of the Kalpin Thrust System in the Southwest Tianshan Mountains During the Late Quaternary显示文摘Deformation patterns, shortening amounts and rates in the late Quaternary across the Kalpin thrust system have received little attention in the past. This paper attempts to discuss them, mainly in the eastern part of the thrust system by doing field investigation along the faults and folds, measuring geomorphic deformation, excavating trenches in several important sites where young alluvial fans were obviously displaced and dating young deposits of alluvial terraces. There are two types of deformation in the surface and near surface for the Kalpin thrust system in the late Quaternary. They are movement of thrust faults on lower angles and bending of young folds. Both kinds of deformation are shown by shortening and uplifting of young geomorphic surfaces. The surface ages of 3 stages are calculated by dating 20 examples using the TL method in the study area and comparing the results of our predecessors on the deposition and incision times of alluvial terraces in the Tianshan mountain which are 100ka B.P., 33~18ka B.P. and 6.6~8.2ka B.P. respectively for the large-scale deformed alluvial surfaces: T_3, T_2 and T_1 in the Kalpin region. Then, 19 sets of shortening amounts and rates are obtained in 13 sites along 4 rows of anticlines in front of the Kalpin thrust system and Piqiang fold. The shortening amounts and rates show that there are two sections where deformation is stronger than others. The two sections consist of two arcs that are towards the south. The shortening rates near the top of arcs are 1.32mm/a in the west and 1.39mm/a in the east across the thrust system, respectively. In addition, deformation is stronger in the front rows than the rear ones for bifurcate folds. | Ran Yongkang Yang Xiaoping Xu Xiwei Cheng Jianwu Chen Lichun | 2007 | Earthquake Research in China2007，21，2： | 0 |
| 19 | Characteristics of Large Earthquake Recurrence and Determination of Average Recurrence Interval Value显示文摘Paleoearthquakes in the Yanqing-Huailai basin and on the Haiyuan fault are studied in detail.The result indicates that the recurrence behavior of large earthquakes is of a wide variety.Characteristic earthquakes show the behavior characteristics of the activity of most faults,butthey are of different grades,the recurrence interval of large earthquakes is of staged nature,and the interaction between faults has effects on the recurrence sequence of large earthquakes.Thus,when the recurrence behavior of large earthquakes is staged in time or when thegradation of characteristic earthquakes has led to a sharp difference in recurrence intervalbetween paleoearthquakes of different intensities,for estimating the large earthquake risk bythe deterministic method and time-dependent probabilistic method,it is necessary to calculatethe recurrence interval value separately for each specific stage or grade in order that theaverage recurrence interval values of different stages can be determined. | Ran Yongkang and Deng QidongInstitute of Geology, China Seismological Bureau, Beijing 100029, China | 2000 | Earthquake Research in China2000，14，1： | 0 |
| 20 | Ecological thresholds of phytoplankton community across environmental gradients in the harmful algal blooms-frequently-occurring,subtropical coastal waters,East China Sea显示文摘Phytoplankton communities can response immediately and directly to environmental changes,and thus have been applied as reliable biotic indicators in aquatic systems.This study provided insights into the relationships concerning ecological thresholds of phytoplankton communities and individual taxon in response to environmental changes in coastal waters of northern Zhejiang Province,East China Sea.Results demonstrated that there existed seasonal variations of phytoplankton community ecological thresholds of which spring being higher than those in summer.As for individual species,Prorocentrum donghaiense and Noctiluca scintillans were identified as the most tolerant and sensitive indicator species in spring and summer,respectively.They exhibited strong indications in response to environmental changes.These findings highlighted that phytoplankton community structure in this region was stable when environmental gradients were below the thresholds of sensitive species,whereas potential harmful algal blooms may occur when environmental gradients exceeded the thresholds of tolerant species. | Ran Ye Chunying Ge Qiong Wang Qing Xu Guofeng Xu Yongkang Yan Mingli Qin Yanhong Cai Yuejun Fei | 2021 | Acta Oceanologica Sinica2021，40，6： | 0 |
