摘要 本文根据浙赣地区火山岩型铀矿床同位素地质资料,分析了浙赣火山岩铀矿成矿物质、成 矿热液的来源,认为该区成矿热液主要由大气降水和岩浆水所组成,成矿物质主要来源于火山岩和周围地层,区域内不同矿床成矿流体的混合比例是不同的,但成矿物质来源几乎相同。 Basing on the isotopic geochemical data in Zhejiang-Jiangxi area uranium deposits in volcanic rocks, analyzing the sources of mineralizing material and mineralizing solution, the authors suggest that mineralizing solution was composed of meteoric water and magmatic water, and mineralizing material was mainly supplied by volcanic rocks and stratum, the mixed proportion of mineralizing solution in different deposits is different, and the source of mineralizing material in different deposits is almost same.
