| 1 | Tectonic implications of Late Paleozoic stratigraphic distribution in Northeast China and adjacent region显示文摘An analysis of the distribution of the Late Paleozoic strata on Northeast China and adjacent region reveals a zonal pattern of the distribution around the core of the Jiamusi-Mongolia Block.The main part of Late Paleozoic marine strata in this area is considered the continental margin deposits of the Jia-musi-Mongolia Block by analyzing the stratigraphic contact relationship,lithofacies,etc.The results are exhibited in a series of tectonic paleogeographic maps.This presents an important proof for the foundation of the Jiamusi-Mongolia Block,and confines the forming time of Jiamusi-Mongolia Block to the Late Silurian. | ChengWen Wang YueWu Sun Ning Li GuoWei Zhao XiaoQin Ma | 2009 | Science China Earth Sciences2009，52，5： | 36 |
| 2 | A Spore-Pollen Assemblage from the Damoguaihe Formation in the Tamutsag Basin, Mongolia and Its Geological Implication显示文摘Based on the palynological data from Well Ta-19-36 and Well Ta-19-37 in the Ta'nan Sag, and Well Ta-22-1 and Well Ta-21-1 in the Bayin Gobi Sag, a spore-pollen assemblage from the Damoguaihe Formation is named as Cicatricosisporites minutaestriatus- Aequitriradites spinulosus-Protopinus sp. assemblage in the Tamutsag Basin, Mongolia. The assemblage is characterized by abundant gymnosperm pollen and diverse fern spores, counted 46.35%–65.57% and 34.43%–52.58% in percentage respectively. Among the gymnosperm pollen, Pinuspollenites sp.(2.66%–16.94%), Protopinus sp.(0–11.38%) and Protopicea sp.(0–10.81%) are dominant; and Alisporites sp., Cerebropollenites sp., Podocarpidites sp., and Abietineaepollenites sp. are common. Some important elements, such as Chasmatosporites sp., Callialasporites prominulus, Parvisaccites sp., Parcisporites sp., Jiaohepollis cf. annulatus, J. bellus, J. verus, Polycingulatisporites sp., Schizaeoisporites certus, Classopollis annulatus are seen. Within the fern spores, Osmundacidites wellamanii(0.85%–4.93%), Appendicisporites sp.(0–4.45%), Baculatisporites comaumensis(0.80%–2.87%), Cicatricosisporites sp.(0.51%–2.66%), C. minor(0–2.14%), Foraminisporis asymmetricus(0–2.40%), Aequitriradites sp.(0– 2.19%) and Cyathidites minor(0–2.13%) are dominant; and some specie of Densoisporites, Cooksonites, Impardecispora, Pilosisporites, Schizaeosprites, Fixisporites, Leptolepidites, Trilobosporites, Kuylisporites, Klukisporites, Hsuisporites, Couperisporites, Maculatisporites are seen. The angiosperm pollen are rare in the assemblage, characterized by Clavatipollenites sp.(0–0.80%) and Songipollis sp.(0–0.27%). The geological age of the Damoguaihe Formation is assigned to Hauterivian – Barremian of Early Cretaceous according to the palynological data, due to the fact that there existed a lot of diverse spores of the family Schizaeaceae and prosperous gymnosperm saccat pollen which the corpus and sacci are differentiated completely, and the presence of early angiosperm pollen of Clavatipollenites. However, the zircon U-Pb isotopic dating of the volcanic rocks in the Nantun Formation indicated that the overlying strata of the Nantun Formation, i.e. the Damoguaihe Formation must be younger than 127.0±2.0–137.9±1.5 Ma. This is consistent with the palynological data. Furthermore, the vegetation reconstructed on the palynological data of the Damoguaihe Formation is conifer forest with shrubs and grassland, belonging to the semi-humid or humid middle to south subtropical climate. Moreover, three new species, namely Biretisporites punctatus sp. nov., Chasmatosporites reticulates sp. nov. and Concentrisporites contractus sp. nov. are described here. | WANG Liyan WAN Chuanbiao SUN Yuewu | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 12 |
| 3 | Lopingian mixed floras from Linxi Formation in Soron area,Inner Mongolia显示文摘A lot of well-preserved plants from the Linxi Formation are collected in the Soron area,Inner Mongolia,consisting of 34 species of 16 genera. They are Late Permian in age. The flora is characterized by a lot of Angaran plants,such as Paracalamites,Comia,Rhachiphyllum,Iniopteris,Rufloria,etc. Some Cathaysian elements,such as Lobatannularia lingulata,L. multifolia,Fascipteris Cathaysiantus,F. densata,Taeniopteris szei,Cladophlebis liulinensis and C. permica,are also mixed within the present flora. This indicates that the Soron of Inner Mongolia was located in the sector between the Angaran and Cathysian floristic provinces in Lopingian. It is beneficial for depicting the location and the evolution of the Solenker--Xar Moron suture zone in the phytogeographic view. The transmigration of tropical and subtropical Cathaysian plants to the north indicates that the Paleoasian Ocean was closed during the late Permian along the suture zone. | ZHANG Dejun SUN Yuewu DING Haisheng YANG Zhenyuan TANG Lijing | 2014 | Global Geology2014，17，2： | 10 |
| 4 | Sporopollen Assemblages from the Cretaceous Yimin Formation of the Hailar Basin,Inner Mongolia,China显示文摘Three sporopollen assemblages are recognized for the first time from the Cretaceous Yimin Formation in the Hailar Basin of eastern Inner Mongolia. They are (in ascending order): the Impardecispora-Aequitriradites-Clavatipollenites assemblage; the Triporoletes-Pilosisporites-Asteropollis assemblage; and the Appendicisporites-Asteropollis-Tricolpites assemblage, distributed in Members 1, 2 and 3 of the Yimin Formation respectively. Recognition of this biostratigraphic sequence is very important for the division and correlation of the Yimin Formation in the basin. Meanwhile, the age of the Yimin Formation is considered to be Barremian to Early Albian based on the palynological data. | WAN Chuanbiao QIAO Xiuyun XU Yanbin SUN Yuewu REN Yanguang JIN Yudong GAO Ping LIU Tongyan | 2005 | Acta Geologica Sinica(English Edition)2005，79，4： | 9 |

| 6 | Stratigraphic framework of late Paleozoic in northeastern China显示文摘Late Paleozoic strata in northeastern China are distributed in a zonal pattern around the old-land on the Jiamusi-Mongolia Block.They are composed of active deposits in the regular distributed tectonic lithofacies zones.This indicates that the late Paleozoic strata belong to continental margin deposits.According to the strong conformability of the sedimentary strata in the same continental margin and distinct differences among the three continental margins,three stratigraphical regions of the Jiamusi-Mongolia Stratigraphical Province are recognized along the northern,southern and eastern margins of the Jiamusi-Mongolia Block,named respectively as Xing'an Stratigraphical Region,Inner Mongolia grass--Songhua River Stratigraphical Region and Baoqing--Hunchun Stratigraphical Region.Due to the characteristics of continental margin deposits and active sediments,the strata can be correlated on the level of formation by the methods of analysing the rock association in the same stratigraphic region.Therefore,some revisions of the lithological formations of the late Paleozoic strata in northeastern China have been made,and a new chart of lithostratigraphic correlation has been proposed.Furthermore,the present stratigraphic framework is setting on the International Stratigraphic Chart on the level of stage,after comprehensive researches to lithostratigraphy,biostratigraphy and chronostratigraphy,especially the conodont biostratigraphy and isotopic ages of volcanic rocks obtained in recent years. | WANG Chengwen LI Ning SUN Yuewu ZONG Pu ZHAO Guowei LIU Hui MA Xiaoqin | 2013 | Global Geology2013，16，1： | 4 |
| 7 | Neogene palynological assemblages in the west slope of Songliao Basin and their geological implications显示文摘Abundant palynological fossils are found from the drill core in the west slope of Songliao Basin, the first full coring borehole that drilled throughout the Neogene. Two Palynological assemblages are recognized according to their vertical distributions, i.e., the late early Miocene–middle Miocene assemblage from the Da'an Formation named as Caryapollenites simplex-Momipites coryloides-Celtispollenites sp.-Tsugaepollenites igniculus, and the late Miocene-early Pliocene assemblage from the Taikang Formation named as Artemisiaepollenites minor-Betulaceoipollenites sp.-Carpinipites sp.-Polypodiaceaesporites sp. On the basis of the composition of each assemblage, we infer that the climate was warm-temperate to sub-tropic during the late early Miocene–middle Miocene and the vegetation was mainly deciduous broadleaved forest and subordinate coniferous and broad-leaved mixed forest with few understory ferns, and probably some shallow fresh water wetlands. The climate then turned cooler and drier in the late Miocene–early Pliocene, represented by the development of xerophytic herbs and temperate plants, although the canopy of the forest remained relatively stable. The results significantly improve the understanding of the Cenozoic palynostratigraphy in the Songliao Basin, and provide new data for both stratigraphical correlation and paleovegetational and paleoclimatical analysis in adjacent area. | WAN ChuanBiao SUN YueWu XUE YunFei QIAO XiuYun JIN YuDong ZHANG YiYong | 2014 | Science China Earth Sciences2014，57，10： | 3 |
| 8 | Discovery of Late Permian Jianshanzi volcanic rocks in Qinghe valley of northern Liaoning and its geologic significance显示文摘Jianshanzi volcanic rocks at Qinghe valley in the northern Liaoning were considered belonging to Early Proterozoic Gaojiayu Formation of Liaohe Group, or to Early Cambrian Beidagou Formation of Qinghezhen Group, or Middle-Late Proterozoic Shenjiapu Formation-Complex of Kaiyuan Group-complex. Dating the zircons from the dacite with schistosity is 2 506 Ma in method of U-Pb (SHRIMP). This evidence indicates the rocks may be referred to Late Permian in age. Discovery of the rocks is significant to re-recognize stratigraphic property of 'Liaohe Group', regional geotectonic location and revolution of orogenic zone in Qinghe valley of the northern Liaoning. | Yuejun CHEN Chunlin SUN Yuewu SUN | 2008 | Global Geology2008，11，3： | 2 |
| 9 | Organic-rich formation and hydrocarbon enrichment of lacustrine shale strata:A case study of Chang 7 Member显示文摘Lacustrine shale is an important target for the exploration of unconventional oil and gas in China beyond marine shale gas.However,the formation environment of lacustrine shale differs from that of marine shale,resulting in a different reservoir composition,organic matter,oil and gas content,and hydrocarbon mobility.In this study,the Chang 7 shale of the Yanchang Formation in the Ordos Basin was used to analyze the effect of volcanic activity on the paleoproductivity and preservation conditions during the formation of lacustrine shale.The results show that algae and bacteria were developed before the eruption.After the eruption,the number of bacteria declined,but the increased prosperity of algae reflects that the volcanic activity enhanced ancient productivity.The sulfate generated by volcanic activity promotes bacterial sulfate reduction,and the produced H_(2)S leads to a strong reducing environment in the waterbody,which is conducive to the preservation of organic matter.Organic geochemical analysis shows that the black shale in the shale strata has a high total organic carbon(TOC)content and strong hydrocarbon generation potential,whereas the tuff has a low TOC content and can scarcely generate hydrocarbons,indicating that the tuff deposited by volcanic activity cannot be considered as effective source rock.In terms of storage space,shale is mainly laminar and dispersed,and it includes organic and inorganic pores.The development of organic pores is affected by thermal maturity,whereas inorganic pores mainly occur between detrital particles and crystals.Tuff is mainly supported by heterogeneous matrix and associated with alteration.Its pores include inter-and intragranular mineral pores.The development of tight sandstone pores is affected by compaction,cementation,and dissolution,which mainly consist of intra-and intergranular pores.The Chang 7 lacustrine shale generally contains oil,but different lithologies have different oil drainage efficiencies.Sandstone and shale exhibit the best and worst oil drainage efficiency,respectively.It is mainly affected by the pore size distribution,fluid properties,and rock wettability.Therefore,the development of shale oil should mainly focus on lacustrine shale formations with interbeds.The mutual dissolution of organic matter and hydrocarbons in the shale section leads to the poor mobility and difficult development of hydrocarbons. | Quanyou LIU Peng LI Zhijun JIN Yuewu SUN Guang HU Dongya ZHU Zhenkai HUANG Xinping LIANG Rui ZHANG Jiayi LIU | 2022 | Science China Earth Sciences2022，65，1： | 2 |

| 13 | Middle and Late Permian palynoflora in Tianshan Township,southeast of Bogda Mountain,Xinjiang,China显示文摘The Permian is one of the most important periods during which the vegetative earth witnessed the transition from icehouse to greenhouse climate and the global environment changes.Organisms on the planet encountered great challenge and the demise of swamp caused the extinction of arborescent lycopods and the rising of Mesophytic plants accomplished the floral transition from the Paleophytic to Mesophytic vegetation.In order to depict the climatic changes and floral succession in the middle and high latitudes of the North Hemisphere,palynological investigation was engaged,and 40 samples collected from the uppermost of Taerlang Formation,Hongyanchi Formation and Quanzijie Formation in the Tianshan Town,Turpan-Hami Basin,eastern Xinjiang,China.The result shows that the palynoflora in the studied area is composed of 50 species of 33 genera,dominated by disaccites and striatiti gymnosperm pollen,and characterized by diverse Protohaploxypinus,Hamia-pollenites,Alisporites and Klausipollenites.It is quite similar to those Middle and Late Permian palynological assemblages reported in the Dalongkou section and other localities in southern margin of Junggar Basin,and aged at Middle and Late Permian.The diversity of typical Angara and sub-Angara pollen,such as Falcisporites,Alisporites,Protohaploxypinus,Vittatina,Lunatisporites,Hamiapollenites,etc.indicates that the studied palynoflora belonged to the sub-Angara phytoprovince,while the presence of Lueckisporites virkkiae implied Euramerica pollen intruded northward sometimes.The paleoclimate of the studied area might be warm and humid with fluctuated dry seasons during the late Guadalupian and early Lopingian time. | Muhammad I.Asghar ZHANG Shuqin ZHANG Minda SHI Xiao SUN Yuewu | 2021 | Global Geology2021，24，4： | 1 |
| 14 | The short-time effects of chemotherapy with combinations of hydroxycamptothecine and oxaliplatin in treatment of advanced colorectal cancer显示文摘Objective: Although 5-fluarouracil-based chemotherapy has become a standard regimen for treatment of ad- vanced colorectal cancer, the efficacy, as second line therapy, is not high. It is necessary to find a new regimen as a substitute for these patients. The study was to evaluate the short-time effects and toxicity of combination of HCPT plus L-OHP regimen in treatment of advanced colorectal cancer. Methods: Forty-seven patients with pathological evidence of advanced colorectal cancer were enrolled and were treated with HCPT plus L-OHP regimen for 86 cycles. All patients were treated with L-OHP 130 mg/m2 day 1 and HCPT 6 mg/m2 day 1–4, the chemotherapy was repeated every 3 weeks as a cycle. The Short-time efficats and side effects were evaluated after 2 cycles for each patient. Results: 38 cases can be evaluated to short-time effects and achieved the overall response rate (CR+PR) was 36.8%. KPS improved in 20 cases (52.6%). In the total 86 cycles, the leuco- penia occurred in 59 cycles (68.6%),18 cycles (30.5%) in grade III and IV and the diarrhea occurred in 48 cycles (55.8%), 18 cycles (37.5%) in grade III and IV. Conclusion: A satisfied response rate was obtained in advanced colorectal cancer patients treated by HCPT plus L-OHP regimen, especially who were the failure of first-line chemotherapy with 5-FU. The limited-dose toxicity was leucopenia and diarrhea. | Yuanjue Sun Hui Zhao Yuewu Guo Feng Lin Xun Cai Xiaochun Tang Yang Yao | 2007 | The Chinese-German Journal of Clinical Oncology2007，6，1： | 1 |
| 15 | Early Jurassic Flora and Stratigraphy from Shansonggang of Southern Jilin,China显示文摘More than 35 species belonging to 22 genera of fossil plants are recognized by the authors from the Shan-songgang flora in the Shansonggang Basin of Jilin, China. Among them, the coexistence of Coniopteris and Cycadocarpi-dium demonstrates that the present flora possesses the characters of the early assemblage of Early Jurassic floras in Eura-sia. Therefore, the age of the Shansonggang flora is considered the Early Jurassic.This study would be beneficial for bet-ter understanding the paleoecological and paleoclimatic characteristics of the Shansonggang Basin. Based mainly on the characters of the flora, the authors suggest that the Lower Jurassic coal-bearing strata, the Shansongang Formation, should namely be renewed. | Fengxiang Liu Yuewu Sun Chunlin Sun Jiansheng Lu Yanhua Zhao | 2003 | Global Geology2003，8，1： | 1 |

| 18 | Division and correlation of Yixian Formation in western Liaoning,China显示文摘The Yixian Formation is a series of volcanic-sedimentary rocks in Biepiao area of Liaoning Province. It is mainly composed of basic and intermediate-basic volcanic lava,pyroclasts and terrestrial sedimentary rocks. Based on the regularity of volcanic activity,the Yixian Formation was divided by the present authors into four members in ascending order:the first member is of basal conglomerate,basic and intermediate-basic volcanic rocks; the second member is of lake phrase sedimentary rocks,or in another word,precious fossil-rich sedimentary beds; the third is of basic volcanic rocks; and the fourth is of upper conglomerate. Field mapping and comprehensive study also indicate that there are abundant vertebrate fossils (mainly of Psittacosaurus) in the first member of the Yixian Formation,and the Jehol Biota (including Sinosauropterxy,Confuciusorns sanctus,Archaefructus,etc.) is yielded in the second member of Yixian Formation. From west to east,the volcanic activity of Yixian Formation changed regularly from early to late,and from basic and intermediate-basic to acid (alkali). | ZHAO Liang XING Dehe' SUN Chulin SUN Yuewu ZHANG Lidong GUO Shengzhe ZHANG Changjie PENG Yandong JIA Bin CHEN Shuwang DING Qiuhong ZHENG Yuejuan | 2010 | Global Geology2010，13，3： | 0 |
| 19 | Androecium of Archaefructus,the Late Jurassic Angioperms from Western Liaoning,China显示文摘Androecium of the earliest known flowering plant Archaefructus liaoningensis was found from the Upper Jurassic Jianshangou Formation of western Liaoning, China. The androecium consists of numerous stamens bearing in pair on the reproductive axes below conduplicate carpels. The stamens are composed of a short filament and basifixed anther for each. Monosulcate pollen in situ are found from the anthers. The characters of the androecium reveals that Archaefructus are probably protandrous, and the paired stamens and monosulcate pollen appear to indicate that Archaefructus, as primitive angiosperms,might be derived from extinct seed -ferns during the Older Mesozoic. Archaefructus is considered Late Jurassic in age. | SUN Ge, ZHENG Shaolin, SUN Chuntin, SUN Yuewu(Research Center of Paleontology & Stratigraphy, Jilin University, Changchun 130026, China)David L.
