| 摘 要： | 中新生代以来,江西萍乐(萍乡-乐平)凹陷带的构造-沉积演化经历了三期四个阶段,即:印支期大规模的推覆、燕山早期晚三叠世末的基底拆离和褶皱-逆冲以及早侏罗世末的盖层滑脱、喜山期新近纪盖层和基底的滑覆,反映盆地性质具有断(裂)陷与坳陷的多次转换特征.构造运动对煤层的控制也表现为坳陷导致煤系地层盖层加厚、埋藏加深及错断、重复... |

| Abstract: | The formation of the Ping(Pingxiang)-Le(Leping) coal-bearing depression zone was strictly controlled by three-period and four-stages of tectonic-sedimentary evolution from Mesozoic to Cenozoic.These include Nappe-stage in Indosinian,basal-detachment and fold-thrust stage in the end of the Late Triassic and cover strike-slip stage in the end of the Early Jurassic,and cover and basal sliding stage during Himalayan.Thus,multistage conversion between sag and fault depression made the basin type of the Pingle de... |
