若尔盖铀矿床位于西秦岭褶皱带之南亚带,作为中国著名的碳硅泥岩型铀矿床之一,该地区的铀矿不仅规模大,品位较富,而且分布较集中,并伴有多种金属可供综合利用(陈友良等,2004;金有忠等,2005)。我国铀矿地质工作者根据碳硅泥岩型铀矿的主导成矿作用,将其划分出风化壳型、沉积-成岩型、淋积型和热液叠加改造型4大类,并根据赋矿岩性划分出9个亚类。若尔盖铀矿床属于热液亚型,它
As one of the famous carbonaceous mudstone type uranium deposits in China, the Zoigou uranium deposit is located in the South Asia Belt of the West Qinling Fold Belt. The uranium deposits in the area are not only large in size and rich in grade but also more concentrated in distribution with a variety of metals For comprehensive utilization (Chen Youliang et al., 2004; Jinyou Zhong et al., 2005). Based on the dominant mineralization of carbonaceous mudstone-type uranium deposits, uranium geology workers in our country divide them into four major categories: weathering crust type, sedimentary-diagenetic type, depositional type and hydrothermal superposition and remolding type, Divided into 9 subcategories. Ruoergai uranium deposits belong to hydrothermal subtype, it
