川西晚三叠纪前陆盆地研究现状

The status quo of Late Triassic foreland basin in West Sichuan

本文纵观晚三叠世川西前陆盆地研究现状,认为目前川西前陆盆地的主要争议在于形成机制、形成时间、前隆位置及盆地范围以及沉积相带划分4个方面。认为解决争议的关键在于加深对龙门山逆冲断裂带形成、演化的研究以及沉积相带、物源分析的研究。

The research status of late Triassic foreland basin in west Sichuan is reviewed in the article, which suggests that the current disputes in the western Sichuan foreland basin are : formation mechanism, formation time, location of forebulge and scope of the basin, and sedimentary facies division. And the key to solving those disputes is to continue to study the formation and evolution of Longmen mountain thrust fault zone、sedimentary facies and provenance analysis in western Sichuan basin.
