【摘要】 湘东北浏(阳)醴(陵)区位于扬子地台与华南褶皱带的拼接部位,区域构造格局和构造演化历史复杂,多期构造作用造就了湘东北NNE向雁列式断裂系列控制的盆、隆相间的含煤盆地。根据湘东北地区煤田构造格局,提出了6种类型的控煤构造样式,初步阐明了构造控煤的基本规律,在此基础上分析其对煤系赋存的影响程度。分析表明:湘东北地区煤田构造复杂,控煤构造样式以各种滑脱构造为主,推覆构造体系下找煤是今后工作的重点方向。更多还原

【Abstract】 The Liuyang-Liling area in northeastern Hunan is situated on the jointing part of the Yangzi platform and South China folded belt,tectonics framework and structural evolution history are very complex,multiple staged structural actions have formed northeastern Hunan NNE en echelon faulted system controlled basins and uplifts alternative coal-bearing basins.Based on coalfield structural framework in northeastern Hunan area,6 types of coal controlling structure style have been advanced.Tentatively expounded basic regular patterns of structural coal controlling,and analyzed their impact extent to coal measures hosting.The analysis has demonstrated that the coalfield structures are complex in northeastern Hunan,coal controlling structure styles are mainly different forms of detachments.Coal looking under the nappe system is key emphasis in work henceforth.更多还原
