甘肃省控煤构造样式划分与分析

Analysis of Coal-controlling Structural Mode in Gansu Province

甘肃省地质构造复杂,含煤地层较多。根据主要含煤岩系赋存特征与构造之间的关系,结合野外调查等资料,全省控煤构造样式可划分为伸展构造样式和压缩构造样式2大类,各样式又细分为3小类。

The geological structure of Gansu province is complex and there are more coal-bearing strata.According to the relationship between occurrence characteristics of coal-bearing rock series and structures, combined with field investigation data and so on, the coal-controlling structure styles in Gansu province can be divided into two categories of extentional and compressional patterns,and each pattern can be divided into three types.
