| 摘 要： | 长江中、下游断裂拗陷带的发展过程可分为后雪峰、后加里东和后印支三个阶段。每个阶段都有岩浆活动和与之有关的成矿作用。燕山期开始拗陷带的活动性增强,并具有向大陆裂谷发展的趋势,这种趋势与太平洋板块的北西向俯冲有关。

| Abstract: | The tectonic history of the fault depression belt along the middle-lowerreaches of the Yangtze river can be divided into three stages: post-Xuef-engnian, post-Caledonian and post-Indosinian; magmatism and associatedmineralization appeared during all these stages. Since Yenshanian thedepression belt has been getting more active, tending to turn continentalrift due to the northwestward Subduction of the Pacific plate. |
