浅覆盖区1:5万基岩地质填图实践探索——以准噶尔北缘克什克涅绍喀尔(L45E009020)图幅为例
|
摘要
如何有效"剥离"覆盖层,获取浅覆盖区下伏基岩地质矿产信息,是今后成矿带覆盖区地质调查工作的重要内容之一。文章总结了在准噶尔北缘克什克涅绍喀尔(L45E009020)图幅开展1:5万浅覆盖区基岩地质填图的实践探索中,采用以地球物理方法(重、磁、电、电磁)为先导,融合地质、地球化学、浅钻为一体的综合地质矿产信息探测方法技术,通过综合预测和浅钻验证,进而获取了图幅基岩地质图。实践中,成功预测并发现了覆盖层之下的隐伏蛇绿混杂岩带,可为进一步矿产调查提供重要依据。
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.
