龙永煤田高陂矿区构造特征及其演化

Structural Feafure and Its Evolution in Gaobei Coal Mine of Longyong Coal-field

本文从认识高陂矿区构造特征入手,分析了矿区构造演化过程。文章认为,高陂矿区的褶皱主要是高陂向斜,后期形成了较多次一级褶曲;区内存在三类断层:滑覆断层,边界逆断层,小型断层。印支晚期主要形成三条滑覆断层;燕山早期形成高陂向斜,东西边界断层,次一级褶曲,小断层;燕山中晚期形成南北边界断层,并使高陂向斜南高北低。

The paper is anglysed the mine structural evolution process through the feature of Gaobei area.The Gaobei Syncline is major fold,formed a lot of secondary folds later period.Exists three type of decollement fault ,reversed fault and little fault.Tectonic revolution is following：decollement faut was formed in latter period of Indo-China.Gaobei Syncline in early period of Yanshan;mine rim fault in middle period of Yanshan.and Comolexed the principal fold.
