摘要
河南省碳硅泥岩型铀矿主要产于华北地台区下寒武统辛集组,受含铀层位、构造的控制,铀矿化与地层中磷、有机炭及钒关系密切,铀矿化分三个亚类。铀矿体呈似层状、透镜状,矿床规模较小,成矿时代新。矿化成因为同生沉积和后生富集叠加。同时,对河南省碳硅泥岩型铀矿的前景进行了分析。在华北地台区和秦岭褶皱带,分布着辛集组的三个带,北带是寻找该类型重要靶区。
The Carbonate-Siliceous-argillitic rock type uranium ore mainly occur in the Lower Cambrian Xinji Formation of the North China Platform, And it is controlled by the uranium-bearing horizon and structures. The uranium mineralization are associated with the phosphorus orus,the organic carbon and the vanadium in the formation and can be divided into three subtypes. The shape of ore body are stratiformlike and it is lenticular and small in the scale of the ore body.The metallogenetic epoch is younger. the genesis of uranium mineralization is superimposed with synsedimentary and epigenetic enrichment. Meanwhile prediction on metallogenetic potentiality of Carbonate-Siliceous-argilliticType uranium ore Deposits in HeNan are given. It distributes three belt of Xinji Formation in the North China Platform and the Qinling fold belt.the northern belt is the mainly prospecting target of this type ore.
