吉林省控煤构造对比研究

运用对比分析法,以控煤构造样式为主线,系统总结了吉林省南部和北部煤田构造特征的异同。南部地区以挤压型构造为主,发育逆冲断裂组合为代表的挤压型控煤构造样式组合,煤田构造变形复杂,煤系赋存范围较小;北部地区则以伸展型构造为特征,控煤构造样式以断裂断块组合为主,煤系分布范围相对较大。吉林省南、北煤田构造特征的上述差异与其所处的大地构造位置和所经历的构造演化历程有关。

Comparative Study of Coal-Control Structures in Northern and Southern Jilin Province

Using contrastive analysis method,taking the coal-control structural pattern as the subject term,systematically summarized structural characteristic similarities and differences in northern and southern parts of the Jilin Province.In the southern part is mainly compressive structures,compressive coal-control structure pattern complexes represented by developed thrusting fault complex;coalfield structures were complicatedly deformed,coal measures hosting range is rather small.While in the northern part is ch...
