一、区域铀成矿的基本特点南岭地区的铀矿床,习惯上按成矿主岩的岩性划分为花岗岩型、砂岩型、碳硅泥岩型及火山岩型等四种成矿类型。据现有资料,将各类铀矿床共同的基本特点概括如下: (一) 成矿作用的空间统一性南岭地区的铀矿床,在空间分布上的特点是,不同类型的铀矿床集中分布在加里东隆起带及其边缘、印支-燕山期花岗岩、中-新生代盆地发育的不大的地区内,共同组成同一个铀
I. Basic Characteristics of Regional Uranium Mineralization Uranium deposits in Nanling are traditionally classified into four metallogenic types: granite, sandstone, carbon-silicon mudstone and volcanic rock according to the lithology of the metallogenic rocks. According to the available data, the basic characteristics of all types of uranium deposits are summarized as follows: (I) Spatial Unification of Mineralization The spatial distribution of uranium deposits in Nanling area is characterized by the concentration of different types of uranium deposits The Caledonian uplift belt and its margin, the Indosinian-Yanshan granite and the Meso-Cenozoic basin are not formed in the same area, forming the same uranium
