摘要
长江铀矿田主要控矿要素为构造蚀变带，查清构造蚀变带位置尤其是构造蚀变带深部延伸及产状变化对深部铀矿的预测评价非常关键。从在长江铀矿田开展的电法、磁法综合物探成果看，利用此两种方法可有效推测构造蚀变带深部延伸及产状变化特征，结合其它资料，还可推测不同期次岩体的接触界面，圈定有利成矿区，为铀资源深部预测评价提供有用信息。
The main ore control factors in Changjiang uranium ore field is structural alteration zone.The key factor in the prediction and evaluation of deep uranium deposits is the position of structural alteration zone,especially the deep extension and attitude change of the structural alteration zone.With the results of integrated geophysical prospecting, such as electrical and magnetic methods, carried out in Changjiang uranium ore field,the deep extension and attitude change of structural alteration zone can be effectively predicted by the two methods.Combined with other information,the two methods can predict the contact interface of rocks formed at different periods and delineate favorable metallogenetic area, which can provide useful information for the prediction and evaluation of deep uranium resources.
