Abstract


Tacheng Basin , Institute of Geology, is the focus of attention in recent years, one of the regions . About Tacheng Basin surrounding mountains outcrop has been studied for many results come out , but people under the cover of the Quaternary basin center region also do not know much . About Tacheng Basin basement depth and relief features , common geological studies only According to the geological characteristics of the surrounding mountains and the regional tectonic features extrapolation can not be drawn in detail the characteristics of the substrate . The main reason for this situation is due to the general geological survey carried out only at the surface , the surface is also obtained information about the underground information is obtained through theoretical speculation , so deep in the earth caused a lot of information without regard uncertainty. Earth's gravity field and magnetic field can penetrate the Earth's surface covered by the material , thus re- magnetic detection at the surface deep underground can get the information , this information may be obtained on the inversion of the base under cover information . However, due to gravity and magnetic inversion multiple solutions , gravity and magnetic data for research alone has some limitations . So this is the introduction of the electromagnetic and seismic profiles to solve multiple solutions of the problem . In this paper, geological research as a starting point , raised Institute of Geology, can not completely solve common problems , namely Tacheng The basement features . Using gravity, magnetic , electrical , seismic inversion of geophysical methods , obtained Tacheng Basin basic features. Through this study also deepen the Tacheng Basin geological understanding .
