摘　　要：对竹山下铀矿床中蚀变糜棱岩的矿物成分进行了研究，发现了一种新型Ｕ－Ｗ共生的蚀变糜棱岩型铀矿床，铀矿物主要是晶质铀矿；指出相应的成矿作用为燕山早期（１６５×１０６ａ±）气热高温热液铀成矿作用。On the basis of studying the mineral composition of altered mylonite in zhushanxia uranium deposit,a new type of altered mylonite uranium deposit (U-W coexisting) has been found,and uranium exists as uraninite.It is concluded that the relative mineralization is pneamatohydrothermal uraniummineralization in early Yanshannian stafe (165106a).
