基于区域重磁解释的南黄海及邻区地质结构构造(英文)
|
摘要
通过对南黄海及邻区已有高精度区域重磁资料整理,形成32°-38°N、118°-127°E的1/100万基础数据,结合已有钻井和地震剖面成果进行重磁综合反演与解释,给出了南黄海及邻区主要三级构造区划、断裂发育、古生界地层深度和厚度,以及主要盆地范围及次级凹陷分布,为南黄海前第三系油气前景评价提供了参考依据。
Regional gravity and aeromagnetic data covering the area of 32°- 38° N, 118°-127° E at the scale of 1:1,000,000 are coordinated and integrated in a synthetic study of the South China Yellow Sea and adjacent areas. Depth to magnetic crystalline basement and its structure are determined by magnetic anomaly inversion. Depth to and thickness of the Paleozoic rock are also revealed by gravity anomaly inversion with constrains of the basement and known seismic information from several profiles. Structure units, main faults, basin boundaries, and sub-suppressions are outlined on the basis of gravity data interpretation.
