可探源音频大地电磁测深在新疆喀拉扎地区含铀砾石层勘探中的应用

The Application of CSAMT to the Prospecting for Uranium gravel in the Kalazha region,Xinjiang Province

在新疆喀拉扎地区铀矿调查评价,采用可控源音频大地电磁测深法完成了对剖面的勘测任务,并把勘测结果与已知钻孔和地质资料对比,取得了预期的地质效果,对工作区各剖面目的层位进行了细致划分,评价了工作区层位低阻、中阻、高阻异常,为铀矿远景划分提供了依据。

This paper uses controlled source audio magnetotelluric method （CSAMT）to complete the task of cross-sectional survey in the investigation and evaluation of uranium in the Kala Zha region, Xinjiang Province. When the survey results is contrasted with the known drilling and geological data, Geological effects achieved are expected. Each sectional object layers of the workspace is divided in detail. Then, The paper evaluates the anomalies of workspace horizon is Low resistance, resistance and high resistance. Finally, it provides the basis for the division of uranium prospect.
