综合地球物理勘探方法在团鱼山南部地区构造划分中的应用
本文旨在考察综合地球物理勘探方法在了解覆盖层厚度和基底深度、划分构造形态和走向等方面的有效性,在青海省团鱼山南部地区分别应用重力和可控源音频大地电磁方法开展了地质勘测。在地质解释过程中,综合工区地质资料,并按不同方法的特点进行相互约束。利用地球物理勘测结果,根据地层电性和密度属性,划分了区域的构造形态和走向,建立了团鱼山南部地区的地质构造模型。综合地球物理方法的应用,有效地降低了地球物理勘探的多解性,为精细地质解释提供了依据,为下一步开展全面物探工作和钻探布设奠定了基础。...

| Abstract_FL | 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. |
