| 摘 要： | 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5000—9000m。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。

| Abstract: | Ore-bearing horizon of uranium mineralization belt in south Qinling mainly exist in Diebu Group,Zhouqu Group and Bailongjiang Group of Silurian system.It is a series of carbon-silicon mudstone formation of marine facies with total thickness of 5 000~9 000m,composed of limestone,carbonaceous slate,siliceous rock and siliceous limestone lithologically.The mineralization types of uranium deposit are stratabound carbonaceous and siliceous mud deposit of hydrothermal transromation primarily,and siliceous limesto... |
