| 摘 要： | 重庆市域位于上扬子陆块之川中前陆盆地、米仓山大巴山基底逆冲带和扬子陆块南部被动边缘褶冲带范围。区域构造格局和构造演化历史复杂,多期构造作用形成了渝东北NW-NWW-EW向和渝西渝东渝东南NE-NNE-NW向形态特征。根据重庆地区煤田构造格局,分析了该区控煤构造样式,阐述了构造对煤系赋存的控制程度。研究认为,重庆地区构造复杂,控煤构造样式以挤压压缩构造为主,煤层大部分赋存于褶曲两翼。

| Abstract: | Chongqing area is located in central Sichuan basin of Yangtze block,basement thrust zone of Micang-Daba Mountain and passive fringe thrust zone of southern Yangtze block.Tectonics framework and struc-tural evolution history are very complex,multiple staged structural action have formed northeastern Chongqing NW-NWW-NW and northwestern Chongqing-eastern Chongqing-southeastern Chongqing NE-NNE-NW morpho-logical characteristics.Based on coalfield structural framework in Chongqing area,the paper analyzed the coal controlling structure style,expounded their impact extent to coal measures hosting,Research shows that structure styles controlling coal are mainly compressed tectonic,coalbed occurs mainly at two wings of folds. |
