摘要
通过对江西晚三叠世聚煤盆地发育特征的详细分析,提出了这种盆地形成的构造控制作用,它是在压扭性构造应力场作用下产生次拉张力所形成的一种断陷盆地.这种作用与太平洋板块的俯冲有一定的关系.
Based on the analysis of the development features of Late Triassic coal-bearing basin in Jiangxi, the paper puts forward the structure governing action on this kind of basin formation. The basin is a fault subsidence one formed by strectching force produced under the pressure-turn stress field which is concerned with the dive of Pacific Plate.
