| 1:50 000 Bedrock Geological Mapping in Shallow Overburden Area:A Case Study of Kashkeneshakar Sheet (L45E009020) on the Northern Margin of Junggar Basin |
| It is one of the important contents of geological survey in overburden areas of metallogenic belt in the future to effectively peel off the overburden to obtain geological and mineral resources information of underlying bedrock in shallow overburden areas. During the practical exploration of 1:50 000 bedrock geological mapping in the Kashkeneshakar Sheet, the authors employed geophysical methods (gravity, magnetism, electricity, electromagnetism) as the leading methods, combined with the comprehensive geological and mineral information exploration method and technology of geology, geochemistry, and shallow drilling. Via comprehensive prediction and shallow drilling verification, the authors compiled geological map of bedrocks of this sheet. The authors successfully predicted and found hidden ophiolitic mélange belt under overburden in practice. It will provide important evidence for further mineral resources survey. |
