摘要
湘东北煤田构造复杂,主要表现为褶皱和断裂,尤以逆冲推覆和滑覆构造较为发育,多期次的构造叠加、切割及剥蚀,呈现构造窗和飞来峰,使含煤岩系在平面上零星分布。探讨本区滑脱构造发育的区域地质背景,运用推覆构造理论深入分析了引起逆冲推覆构造和滑覆构造的形成机制,对掌握煤炭资源分布规律、评价湖南煤炭资源潜力有一定的指导意义。
Coalfield structures in the northeastern Hunan mainly in the form of folds and faults, especially thrust nappe and detachment structures. Multiple stages of tectonic overprinting and incision and denudation produce tectonic windows and klippes, which make coal rock formation fragmentary horizontal distribution. Probed into the regional geological setting of detachment tectonics, and analyzed their mechanism by the use of thrust nappe and detachment theories have important guiding importance to find out distribution pattern of coal resources and potential coal resource valuation in Hunan Province.
