Abstract

Abstract

Geological mapping in Gobi Desert covered area is one of the significant contents of geological survey in the new period of geological investigation. The basic objectives of geological mapping in covered area include two aspects: one is to reveal the geological structure of bedrock under overburden, i.e., to draw geological map of the bedrock; and the other is to reveal the geological structure of overburden, including the framework of overburden and the three-dimensional geological structure of overburden. Comprehensive geophysical surveys can be used to obtain the information of the geological structure, rock nature, distribution and layer-structure of sediment, etc. in covered area. Since economy and efficiency are key factors for geological mapping, selection and comprehensive implementation of geophysical methods are important to the investigation. Based on the recent geological mapping work in the East Tianshan mountains, Xinjiang, it proposed an optimal and effective integrated geophysical survey method for dealing with the geological mapping issue under multi-layer overburden in this paper. The integrated geophysical investigation and application of new technology in Barkol Basin and Hami Basin illustrate the efficiency and practicability of the comprehensive method. It may provide a reasonable solution to delineate covered rocks and structures in geological survey in Gobi Desert covered area.
