DONGCHUAN MOVEMENT AND ITS INFLUENCE ON FOLDING STRUCTURES IN DONGCHUAN MINING DISTRICT
-
摘要:
分析了当前东川运动的各种认识，通过上下地层的特征、构造、变质作用、火山-岩浆活动、形成背景以及汤丹、落雪和拖布卡3个典型剖面的研究，确定该运动是一次大规模的构造运动。东川运动是南北向挤压运动，在东川矿区下（昆阳）亚群形成东西向褶皱构造，被后期小黑箐和晋宁运动叠加改造后，其构造形迹变得模糊和复杂，但经仔细研究分辨出了10个较大的褶皱构造。
Abstract:The various understandings about Dongchuan Movement were analyzed. Researches on characteristics of the strata in Kunyang Group, metamorphism, volcano-magma activities, and typical profiles as Tangdan, Luoxue and Tuobuka show that Dongchuan Movement is a large-scale tectonic movement. Dongchuan Movement is SN-trend compressional movement. In Dongchuan mining district, EW-trend fold structures formed in the lower Kunyang subgroup. These EW-trend fold structures were reformed and transformed by later Xiaoheijing Movement and Jinning Movement. The structural features became indistinct and complex. But after a careful study, the 10 larger fold structures were distinguished in Dongchuan mining district.
