摘要
本文以近几年来配合1∶25万带钻区调工作开展的瞬变电磁测深工作为基础,总结了该方法在铀矿区调阶段的应用效果。认为瞬变电磁测深资料有利于判断地下水动力条件及铀矿化的成矿有利区;大范围的瞬变电磁测深工作更适合于在戈壁沙漠区工作,有利于区调选区工作的进行,可达到缩小靶区和提供钻探设计依据的目的,在砂岩型铀矿找矿工作中有推广意义。
Based on the results of transient electromagnetic （TEM） sounding survey during recent years regional geological reconnaissance with drilling （1 ： 250000） , the application effect of TEM sounding survey during regional reconnaissance is summarized in this paper. It is suggested that the data of TEM sounding are useful in judging hydrodynamic conditions of groundwater and determining favorable areas for uranium ore-formation; TEM sounding in large areas may be proper for prospecting in gobi-desert areas and be beneficial for regional reconnaissance and target area selection, and may reduce the target area and provide basis for further drilling program. It is of popularized significance in the prospecting for sandstone-type uranium deposits.
