摘要
川西晚三叠世前陆盆地是中国典型的前陆盆地之一，也是一个重要的含油气盆地。其形成是由于岩石田深部调整作用引起扬子板块自南东往北西持续俯冲，龙门山推覆构造带自北西往南东持续推覆的结果。川西晚三叠世前陆盆地的形成与演化可分为五个阶段：①被动大陆边缘发展阶段；②构造反转阶段；③前陆盆地早期补偿不足阶段；④前陆盆地中期补偿阶段；⑤前陆盆地晚期补偿过足阶段。前陆盆地能为该区石油、天然气、铅锌矿等矿藏的形成提供必要而充分的有利条件。
The hate Triassic foreland basin in West Sichuan is a type of China's foreland basins and also an improtant oil-gas bearing basin. Its formation is the results that Yangzi Plate continuously underthrust from northwest forward to southeast and that Longmen Mountain nappe structural belt continuously overthrust from nouthwest forward to southeast which were caused by the adjustment action of lithosphere deep part. The formation and evolution of Late Triassic foreland basin in West Sichuan can be divided into the singes such as passive continental margin development stage, structure reversal stage, early period deficiency compensation stage of forland basin, medium period compensation stage and late period over compensation sarge of foreland basin. The foreland basin can provide necesary and abundand favourable conditions for forming the mineral resources of oil, gas, lead and zinc.
