| 1 | Characteristics of Meso-Cenozoic Igneous Complexes in the South Yellow Sea Basin,Lower Yangtze Craton of Eastern China and the Tectonic Setting显示文摘The South Yellow Sea Basin is partially surrounded by the East Asian continental MesoCenozoic widespread igneous rocks belt.Magnetic anomaly and multi-channel seismic data both reveal the prevalent occurrence of igneous rocks.We preliminarily defined the coupling relation between magnetic anomalies and igneous rock bodies.Some igneous complexes were also recognized by using multi-channel seismic and drilling data.We identified various intrusive and extrusive igneous rock bodies,such as stocks,sills,dikes,laccoliths and volcanic edifice relics through seismic facies analysis.We also forecasted the distribution characteristics of igneous complexes.More than fifty hypabyssal intrusions and volcanic relics were delineated based on the interpretation of magnetic anomaly and dense intersecting multi-channel seismic data.It is an important supplement to regional geology and basin evolution research.Spatial matching relations between igneous rock belts and fractures document that extensional N-E and N-NE-trending deep fractures may be effective pathways for magma intrusion.These fractures formed under the influence of regional extension during the MesoCenozoic after the Indosinian movement.Isotopic ages and crosscutting relations between igneous rock bodies and the surrounding bedded sedimentary strata both indicate that igneous activities might have initiated during the Late Jurassic,peaked in the Early Cretaceous,gradually weakened in the Late Cretaceous,and continued until the Miocene.Combined with previous studies,it is considered that the Meso-Cenozoic igneous activities,especially the intensive igneous activity of the Early Cretaceous,are closely associated with the subduction of the Paleo-Pacific Plate. | PANG Yumao ZHANG Xunhua XIAO Guolin GUO Xingwei WEN Zhenhe WU Zhiqiang ZHU Xiaoqing | 2017 | Acta Geologica Sinica(English Edition)2017，91，3： | 15 |
| 2 | The mapping methods and division of tectonic units of the regional tectonic map in the eastern China seas and adjacent regions显示文摘The geological-geophysical map series of the eastern China seas and adjacent region (1:1 000 000) will be published in the late half year of 2009. The regional tectonic map is one of the main professional maps. The Mapping methods, the division method of geological tectonic units and the main geological tectonic units are mainly discussed. The strata from Pliocene to Holocene are peeled off so as to display the Pre-Pliocene structures. In basins, isopaches are drawn for the Cenozoic deposits. The plate tectonic theory and present tectonic pattern are adopted as the priorities in tectonic division. As to the division of intraplate tectonic units, it is a revision, complement and improvement of previous dividing systems, and the nomenclature for each tectonic unit follows the current system in China. The first-order tectonic unit is plate (Pacific Plate, Eurasian Plate and Philippine Sea Plate). The second-order tectonic unit is tectonic domain (East Asian continental tectonic domain,East Asian continental margin tectonic domain and west Pacific tectonic domain). The Philippine Sea Plate and the west part of the Pacific Plate are called the West Pacific tectonic domain. The part of the Eurasian Plate involved in this study area can be further divided into East Asian continental tectonic domain and East Asian continental margin tectonic domain. The East Asian continental margin domain is composed of the Ryukyu island arc, the Okinawa Trough back-arc basin and the back-arc basin of Sea of Japan. The East Asian continental tectonic domain in this study area is composed of the Sino-Korea Massif, the Changjiang River (Yangtze) Massif and South China Massif. In turn, these massifs consist of basins, folded belts or uplift zones. The basins,the folded belts or the uplift zones are further divided into uplifts and depressions made up of sags and swells. | YIN Yanhong ZHANG Xunhua WEN Zhenhe GUO Zhenxuan | 2009 | Acta Oceanologica Sinica2009，28，4： | 1 |
