我国中、新生代盆地砂岩型铀矿沉积环境研究概述

Study on Sedimentary Environment of Sandstone-Type Uranium Deposit in Mesozoic-Cenozoic Basin of China

由于可地浸砂岩铀矿对沉积相的条件严苛,对它的研究又相对迟缓,国内外在此沉积环境的资料相对匮乏。该文通过我国中、新生代盆地砂岩型铀矿沉积环境研究的现状及特征,并根据岩石类型、成矿条件和构造状况等并以此为基础提出针对砂岩型铀矿沉积环境研究中要关注的一些问题。

Due to the harsh conditions of in-situ leachable sandstone uranium deposits on the sedimentary facies,research on it is relatively slow,and thus the data on the sedimentary environment at home and abroad is relatively scarce.In this paper,the sedimentary environment and characteristics of sandstone-type uranium deposit in Mesozoic-Cenozoic basin of China were investigated.On the basis of rock type,metallogenic conditions and tectonic conditions,some problems to be addressed in the study of sedimentary environment of sandstone-type uranium deposits are proposed.
