音频大地电磁法在新疆阿依拉苏铀矿勘查中的应用

Prospecting application of audio magnetotelluric method in Ayilasu uranium deposit,Xinjiang

阿依拉苏铀矿点具构造控矿的特征,但地表断层产状较陡,无法判断深部断层延伸情况。文章在综合地质调查的基础上,通过音频大地电磁测深,初步了解地下地质体的空间展布及断层的延伸情况。经钻探工程验证,深部存在铀矿体,最终认为地表矿点为深部含矿体错动地表所致。

The Ailasu uranium ore site has the characteristics of structural ore control, but the occurrence of surface faults is steep, and it is impossible to judge the deep fault extension. Based on comprehensive geological surveys, this paper preliminary understands the spatial distribution of underground geological bodies and the extension of faults through audio magnetotelluric sounding. The drilling project verified that uranium ore bodies existed in the deep, and finally the surface ore spots were thought to be caused by the erroneous surface of deep ore-bearing bodies.
