南海北部陆缘西沙海槽—台湾恒春半岛地学断面

Geotransect from Xisha Trough in the northern continental slope of the South China Sea to Hengchun Peninsular in Taiwan

利用南海北部陆缘及邻区的地质、地球物理资料,综合编制了印支半岛东缘—西沙海槽—南海北部陆坡—台湾恒春半岛—菲律宾海地学断面,从地形地貌、地球物理场、地质构造特征和时空演化等多个方面综合揭示了南海北部陆缘洋陆转换带岩石圈结构及其相互作用,对深入认识南海北部陆缘构造格局和深水区油气地质具有重要意义。

Available geological and geophysical data obtained around the northern continental margin of the South China Sea were used to compile the synthetic geotransect from the eastern margin of Indo-China Peninsular, through Xisha Trough, the northern continental slope of the South China Sea and Henchung Peninsular in Taiwan to the Philippine Sea. This geotransect is about 1800 km in length. The topography and morphology, geophysics, structural geology and time-space evolution reveal the configuration of the ocean-continent boundary and the interaction in the northern continental margin of the South China Sea, which is significant for understanding the tectonic framework and deep water petroleum geology in the northern margin of the South China Sea.
