南秦岭铀成矿带含铀层位主要是志留系迭部群、舟曲群、白龙江群,总体为一套海相碳硅泥岩建造。主要岩性为灰岩、炭质板岩、炭硅质板岩、硅质岩、硅灰岩,总厚5 000~9 000m。铀矿床(点)矿化类型以层控热水改造碳硅泥岩型为主,次为层控炭硅泥岩型。铀成矿以燕山晚期—喜山期为主。铀矿化在空间上可划分为迭部、舟曲—武都、文县—康县矿化集中区。铀矿体的空间展布具有分段集中,成群集结的特点。含铀层位分布广,厚度大,铀源丰富,铀矿床(点)带多且工作程度低,找矿前景好。
South Qinling uranium metallogenic belt containing uranium layer is mainly Silurian Diebu group, Zhouqu group, Bailongjiang group, the overall set of marine carbon-silicon mudstone construction. The main lithology is limestone, carbonaceous slate, carbon siliceous slate, silicalite and wollastonite with a total thickness of 5 000 ~ 9 000 m. The mineralization type of uranium deposit (point) is dominated by layer-controlled hot water alteration of carbon-silicon mudstone type, followed by stratabound carbon-silicon mudstone type. Uranium mineralization in late Yanshan - Himalayan-based. Uranium mineralization in space can be divided into Diego, Zhouqu - Wudu, Wenxian - Kangxian mineralization area. The spatial distribution of uranium ore body has the characteristics of segmented concentration and clustering. Uranium bearing strata are widely distributed, large in thickness, rich in uranium, with many uranium deposits (points) and low degree of work, and good prospects for prospecting.
