摘要
Abstract
The purpose of this work is to examine the effectiveness of integrated geophysical exploration in determining the thickness of overburden, the depth of basement, and the division of tectonic forms and trends. We have collected data of gravity and controlled source audio magnetotelluric ( CSAMT) in the southern Tuanyushan area of Qinghai Province. In geological interpretation, we combined the existing geological data of the survey area with constraints of different geophysical methods. According to the electrical and density properties of the subsurface rock, the tectonic units with distinct forms and trends were divided. Then we established a geological structure model for the study area. Results show that the application of integrated geo-physical methods can effectively reduce the multiple solutions of geophysical data interpretation, providing basis for detailed geological interpretation, and laying the foundation for further geophysical exploration and drilling deployment.关键词
