我国南秦岭碳硅泥岩型铀矿成矿带分布范围广、成矿条件优、潜在资源量大.对南秦岭寒武-志留系区域含矿地层、构造体系、岩浆岩特征开展归纳总结,并以西、中、东部三个不同地段典型铀矿床成矿特征进行简要对比,发现区域铀成矿的共性特征,总结得出区域上浅海半深水的沉积环境是最有利的铀成矿环境,断裂构造为导矿、容矿提供了有利空间通道,深部幔源流体上升为铀富集提供了有利成矿条件.
Analysis of the Metallogenic Regularity of Cambrian Silurian Carbon Silicon Mudstone Type Uranium Deposits in the Southern Qinling Mountains
The carbon silicon mudstone type uranium mineralization belt in the southern Qinling Mountains of China has a wide distribution range,excellent mineralization conditions,and large potential resources.Summarize and generalize the ore bearing strata,structural systems,and magmatic rock characteristics of the Cambrian Silurian region in the southern Qinling Mountains,and briefly compare the ore-forming characteristics of typical uranium deposits in the western,central,and eastern regions.The common features of regional uranium mineralization are discovered,and it is concluded that the sedimentary environment of shallow and semi deep waters in the region is the most favorable uranium mineralization environment.Fault structures provide favorable spatial channels for ore conduction and hosting,and the rise of deep-seated mantle derived fluids provides favorable mineralization conditions for uranium enrichment.
