【摘要】：正龙首山成矿带位于华北地块西南缘,受加里东运动改造,南部祁连裂谷在强大的挤压作用下向北推挤,发生了多次中酸性岩浆的侵入活动,形成了一系列由花岗岩体组成的北西向岩浆岩带,芨岭岩体便是其中之一。自上世纪中后期,在芨岭岩体一带发现了三个中型矿床和大量铀矿(化)点(黄净白,2005),近年来开展了一些资源评价工作,对该区铀成矿特征取得了更深入的认识,在此基础上,仔细分析芨岭岩体的铀成矿地质条件,总结找
[Abstract]:The Zhenglongshoushan metallogenic belt is located in the southwestern margin of the North China block. Due to the Caledonian movement transformation, the Qilian rift in the south is pushed northward under the strong compression, and many intrusions of intermediate-acid magma have taken place. A series of NW magmatic belts composed of granite bodies have been formed, among which the Jiling rock body has been one of them since the middle and late 0th century. Three medium ore deposits and a large number of uranium deposits (Huangjingbai Pai 2005) have been found in the area of Jieling rock body. In recent years, some resource evaluation work has been carried out, and a deeper understanding of the uranium metallogenic characteristics in this area has been obtained. On this basis, the uranium metallogenic geological conditions of the Jiling rock body are analyzed carefully, and the prospecting is summarized.
