Abstract

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.
- Dongchuan Movement,
- folding structure,
- Kunyang Group,
- Dongchuan mining district
