摘　　要：修水碳硅泥岩型铀矿主要有保峰源、董坑、大椿、白土、洞下矿床,矿床集中分布于修水复向斜中,构成修水矿化集中区,该矿化集中区位于修水—宁国—开化碳硅泥岩成矿带西端,是我国重要的碳硅泥岩型铀矿主产地,具有优越的区域铀成矿地质条件。通过铀矿调查评价工作,分析厘定了研究区岩性岩相、构造、岩相古地理、铀源等条件,明确了灯影组、王音铺组碳硅泥岩建造为研究区主要铀源层、赋矿层,新发现了观音堂组中的工业铀矿体。以铀成矿地质条件、铀矿化特征分析为重点,预测铀资源潜力。The arbonaceous-siliceous-argillitic rock-hosted uranium deposits mainlyjinclude Baofengyuan, Dongkeng, Dachun, Daitu, Dongxia in Xiushui area, which are concentrated in Xiushui synclinorium, and formed into mineralization concentration area which is located in western of the Xiushui - Ningguo - Kaihua carbonaceous- siliceous-argillitic rock in metallogenic- belt, it is the main origin of carbonaceous-siliceous-argillitic rock type u- ranium deposits in our country, we have carried out by the uranium survey and evaluation work, an analysis on the area of lithology and facies, structure, lithofacies palaeogeography, uranium source conditions, clearled the Dengying Formation, Wang Yin Pu group of carbonaceous-siliceous-argillitic rock construction for regional urani- um source, host strata, found a new industrial uranium ore body in Buddism godness Guanyin hall group. This page is based on the geological conditions of uranium metallogenesis, uranium mineralization characteristics analy- sis to predict the potential of uranium resources.
