陕西省铀矿矿床类型及成矿模式研究

陕西矿产资源丰富,是我国资源大省之一,许多矿种在全国占有重要地位。陕西是我国重要的铀矿成矿远景区之一,铀矿床主要类型有花岗岩型、混合岩型或变质岩型、碳硅泥岩型、砂岩型和伟晶花岗岩型,伟晶花岗岩型铀矿床是陕西省独特的铀矿类型。文章分别从地质背景、矿体规模、赋矿层位、控矿构造、成矿时期等方面进行了总结,分别论述了铀矿床的成矿类型,对陕西铀矿的成矿模式进行了探讨和总结,以期为今后陕西省铀矿的勘探提供依据。

Mineralization styles and deposit types of uranium in Shaanxi Province

Shanxi has rich mineral resources and is one of large resources provinces in China. Many minerals in Shanxi occupy an important position in our country. Shanxi is one of important uranium mineralization prospect areas in our country. The main types of uranium deposits in shanxi include granite type, mixed rock type or metamorphic rock type, carbon and silicon mudstone, sandstone and giant crystal type granite. The giant crystal granite type uranium deposit is a unique type of uranium deposits in shanxi province in China. This paper summarized respectively the geological background, ore body size, the mineralization location, ore-controlling structure, mineralization period etc, and respectively discussed the mineralization type uranium deposits. This paper discussed and summarized the mineralization model of uranium deposits and provide basis for uranium deposits exploration in shanxi province.
