摘要
分析研究滑脱构造基本特征及其有关铀矿床成矿作用.发现逆冲或滑脱过程中的高温高压和异常高孔隙液压环境,能够促使铀的大规模活化迁移和含铀溶液的形成,因而对铀成矿起了积极作用,滑脱构造带是华南地区找铀的构造标志,尤其应注意在前震旦系逆冲或滑覆到上震旦至下寒武统的地段找铀.
Based on the analysis of main features of the detachment tectonic and the investigation of mineralization of uranium deposits,such as Lagoa Real deposit from Brazi;and No. 661 deposit in South China .related to the detachment tectonic,it is found that the thrusting or detaching environments with high temperature and prssure and anormalous pore pressure could make uranium activized and transported ,playing an active role to uranium mineralization. It is also suggested detachment tectonic is the indicator for uranium deposits prospecting in South China,and attention should be paid to the regions of strata of Pre-Sinian system thrst-ing or sliding on the strata of Upper Sinian and Lower Cambrian.
