摘要
深冲矿区位于苗儿山铀矿富集区,是花岗岩型铀矿产地.本文从地质背景、矿床地质特征、矿石矿物组成、围岩蚀变、包裹体特征、铅同位素组成、氢氧同位素组成等入手,系统阐明深冲矿区铀矿地质、地球化学特征.初步认为该矿床类型为碎裂蚀变花岗岩型,铀成矿物质来源具有壳幔源混合特点,是低温低盐度岩浆热液成因铀矿床.
Shenchong mining area in Miaoershan District rich in uranium,is the the origin of granite type uranium deposits. This paper clarifies uranium geology and geochemical characteristics of Shenchong deposits from the geological background,geological characteristics of the deposit,ore minerals compositions,wall rock alteration,characteristics of fluid inclusion,lead isotopic composition and hydrogen and oxygen isotopic composition. It is considered this deposit belongs to cataclastic altered granite type,and its uranium ore-forming material source has the characteristics of crust mantle mixing of the uranium deposit which is low temperature and low salinity magmatic hydrothermal uranium deposit.
