甘肃省金边寺矿床铀矿化特征及成矿条件分析

金边寺矿床位于龙首山东部的青山堡岩体西南部边缘,其周边还发育有较多铀矿（化）点、异常点,具有较好的铀成矿背景。文章从矿床的岩浆岩条件、构造条件、热液蚀变条件、淋积成矿条件、以及区域上广泛与铀成矿密切相关的碱交代热液蚀变条件进行了全面分析,系统的阐述了该矿床的铀成矿条件。在此基础上,初步探讨了下一步找矿方向,即在该区下一步找矿工作重点是寻找深部未被淋积的碱交代型铀矿体和继续扩大淋积型铀矿化,寻找新的赋矿空间。

CHARACTERISTICS OF URANIUM MINERALIZATION AND METALLOGENIC CONDITIONS OF JINBIANSI DEPOSIT

Jinbiansi deposit is located in the southwest margin of Qinsanbu rock mass which is in the east section of Longshoushan Mountain,where there are a series of uranium occurrences with a good metallogenic setting.The paper studied the magmatic condition,structure condition,hydrothermal condition,subsequent transformation condition,especially the alkali metasomatism which had a close connection with the formation of U ore body.It is great significant for the future prospecting of uranium deposit.
