江西相山构造—岩浆演化与富大铀矿形成

Tectono—Magmatic Evolution and the Formation of Rich and Large Uranium Deposits in Xiangshan of Jiangxi

本文从华南最著名的赣杭构造火山岩成矿带南西段的研究入手,论述了德兴—遂川NE向大断裂经历了"剪切走滑—伸展拉张—挤压逆冲"3个阶段演化。研究表明上述构造演化三步曲对相山构造—火山岩浆活动及铀成矿起着重要的控制作用。

Based on the study of the southwest part of the Gan-Hang tectono — volcanic metallogenic belt in South China, the paper expounds that the Dexing—Suichuan NE-trending regional fault zone experienced three evolutionary stages, i. e, strike-slip shearing, pull-apart extension and compressive thrusting which played the differnt role in controlling volcanic activities and uranium metallogenesis of the southwest part of the Gan-Hang belt.
