找矿地质判据在河元背铀矿普查中的应用

Application of the Geological Prospecting Criterion in the Uranium Deposit Implementation of the Heyuanbei Project

找矿地质判据总结了不同类型铀矿床的形成、富集和分布的有利地质条件和地质环境,为河元背普查项目的实施提供了重要的理论基础。该文主要论述了岩浆活动判据和构造地质判据在研究区的应用,多阶段多期次岩浆喷发、侵入以及围岩蚀变作用强烈叠加,为铀成矿创造了重要条件。区内构造发育,确定断裂构造、火山岩组间界面是有利的赋矿部位。

Geological prospecting criterion summarized the formation of different types of uranium deposits, accumulation and distribution of the favorable geological conditions and geological environment, and provided an important theoretical basis for the implementation of the heyuanbei project. This paper mainly discussed the application of magmatic activity criterion and geological criteria in the work area, multi-period multi-stage magmatic eruption, intrusion and wall rock alteration strong overlay created important conditions for uranium mineralization. Tectonic development in the region to identify faults, volcanic group interface is favorable ore site. In the work area structure was developed and identified faults, volcanic group interface as favorable ore sites.
