Geological structure of the yellow sea area from regional gravity and magnetic interpretation

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.

Zhang Minghua, published, received a PhD in 1995 from China University of Geosciences in Applied Geophysics and finished postdoctoral research at Beijing University of Science and Technology in 1998. Now he is a Senior Research Geophysicist and Director of the Database Center, Development Research Center, China Geological Survey. He has published more than 30 papers in the fields of both geophysical exploration and geo-information systems.
