摘要
大量磷铀矿床 (点 )产于扬子地台边缘海盆 ,含矿岩系为下寒武统 ,矿床产出在适宜的岩相古地理与古构造部位 ,分东西两个成矿带。东带鲁家坪组与西带宽川铺组 ,具有两种不同磷铀矿及其伴生元素组合的岩相特点。西带最重要的是含铀磷块岩 ,以磷 -铀 -钒组合为特点。而东带则较复杂 ,有 :碳硅板岩铀 -钡 -磷组合 ;硅质板岩铀 -磷 -矾组合 ;重晶石 -石英脉中铀 -钡组合。东带镇巴区三种组合类型铀 (磷 )矿形成与造山运动关系密切 ,而西带宽川铺区磷 (铀 )
There are a lot of phosphorus/uranium deposits (spots) in marginal basins along Yangtze platform, hosted in Early Cambrian strata and controlled by some specified paleogeographic and paleostructural positions. Two mineralizing belt have be defined: the eastern Lujiaping group and the western Kuanchuanpu group, one differing from the other in terms of association of phosphorus/uranium ore and accompanying elements. The western is highlighted by uranium bearing phosphorite, characteristic of association of phosphorus and uranium and vanadium while the eastern is complicated by three kinds of mineral (or rock) association including uranium containing carbonaceous and siliceous slate and barium and phosphorus, uranium carrying siliceous slate and phosphorus and vanadium, and uranium bearing quartz vine and barite and barium. These three uranium mineralizations in the Zhenba area of the eastern belt have a close link with orogenic movement, comparaed with the western whose uranium minerlizations may be attributed to thalassogenic movement.
