| 摘 要： | 六枝煤矿区属于威宁—郎岱褶皱束的一部分，NW向构造占据主要地位。地史上该区有多次升降运动，二叠纪的东吴运动，伴随基性岩浆活动；侏罗、白垩纪的燕山运动，使本区发生大规模的褶皱和断裂；喜马拉雅运动的影响使本区构造复杂化。形成NE向扭性断层；构造复合的基本方式是横跨和限制。构造分析表明，NE向构造形成较早，NW向构造形成较晚。

| Abstract: | As being part of Weining-Langdai fold cluster, the northeast-striking structure is in the lead position in Liuzhi coal province. Multiple up-and-down movements arise of the province in geo-history, as well the Dongwu movement of Permian accompanying the basic magma activity; Jurassic and Cretaceous Yanshannian movements give rise to the folds and the faults in large-scale development; The structures that are influenced by Himalayan movement take on complexity. The basic models on structural compounding are transverse cross and limits. By analysis it indicates the structure in northeastward trend takes shape earlier and one striking north west forms later. |
