摘    要:郯庐断裂是我国东部一条大型的超壳断裂,它影响和控制了沿带的主要沉积特征和构造演化。随着新的勘查成果和矿区生产资料的积累,郯庐断裂带对辽中煤田沉积和构造控制作用等方面的认识也进一步深入,分析认为郯庐断裂带中、新生代以来的发育史分为三期,即晚侏罗世—早白垩世左行平移期、晚白垩世—古近纪伸展期和新近纪以来的右行挤压期。同时详细分析了各个时期郯庐断裂带对辽中煤田(红阳煤田、永乐煤田、沈北煤田、本溪煤田等)构造样式的影响,研究结果对煤炭资源进一步勘查具有指导意义。

关 键 词:郯庐断裂  辽中煤田  构造控制  左行走滑  断陷作用

Abstract:The Tancheng-Lujiang fault is a large-scale crust cut fault in eastern China, it influences and controls both sides' main sedimentary features and tectonic evolution. Along with accumulation of new exploration results and mine area production data, the knowledge of structural controlling of Tancheng-Lujiang faulted zone on structures in the central Liaoning coalfields is steadily deepening. The analysis considered that the development history of the faulted zone during Mesozoic and Cenozoic can be divided into 3 phases, namely Late Jurassic-Early Cretaceous sinistral translation phase, Late-Cretaceous-Paleogene extension phase and Neogene compression phase. Meanwhile, analyzed influences from Taneheng-Lujiang faulted zone on structural forms in central Liaoning coalfields (including Hongyang, Yongle, Shenbei and Benxi coalfields etc.) in each phase in detail. The result has guiding significance in further exploration of coal resources in the area.
Keywords:Tancheng-Lujiang fault  central Liaoning coalfields  structural control  sinistral strike-slip  rift faulting
