广东河源成矿带铀资源现状及成矿潜力分析

Analysis on uranium resources situations and metallogenic potential of Heyuan mineralization belt of Guangdong province

河源成矿带是条多次活动的构造岩浆活动带,具有强烈塑性流变和剪切的特点。早期形成挤压逆冲(推覆)构造,晚期拉伸型滑覆形成铲状正断层并控制红盆(K2-E)和铀矿化。综合研究分析表明:该区成矿条件有利、铀资源丰富、地质工作程度较高,是寻找新矿床的有利靶区。

Heyuan mineralization belt is a structure-magmatic activities belt which is charcterized by strong plastic deformation and shearing. The squeeze （overthrust） structure is formed early. Later stretch produced slide shovel-shaped normal fault which control the red basin and uranium mineralization. Comprehensive study shows that this area is of favorable uranium metallogenic condition due to the rich uranium source and higher degree of geology work, it is a target for the new round resources exploration.
