| 摘 要： | 含铀混合岩大部分位于古陆隆起带边部、ＮＷ向花岗岩外接触带。深大断裂系统在成矿成岩中占有相当重要的地位。燕山期构造和岩浆活化，对原有的构造和矿化进行了强烈改造。在混合岩中发现了两种主要成矿类型，即铀一赤铁矿型和铀一碳酸盐型。

| Abstract: | In this paper, at first, the author discussed the geologic setting of uraniferous migmatite. Most of the uraniferous migmatite are located in the older uplifted zones and NW exocontact of the graniticbodies. The deep fault systems have played a very important part in diagenesis and ore formation origi-nal geological structure and mineralization were intensely reworked by the Yenshanian tectonic andmagmatic mobilization.Two metallogenic types were found in this migmatite,that is to say the uranium-carbonate typeand uranium-hematite type. |
