Based on analysis of heavy minerals, detrital components of gravel - bearing coarse fragments, maturity of minerals and clay components of mudstones, it is believed that Jurassic would have sourced mainly from two directions, which are the southern Kuluke Mountain and the western Tashidian area respectively.
通过对该区重矿物、含砾粗碎屑组分、矿物成熟度及泥岩粘土成分等的分析,认为该区侏罗系存在两个主要的物源方向,一个来自南部库鲁克山,另一个来自西部的塔什店地区。
Methods Using the three parameters of heavy mineral assemblage of detrital rock,coarse fragment component and mineralogic maturity,the basin sedimentary boundaries will be foun and studied.
方法从大量的地质资料入手,利用碎屑重矿物组合、粗碎屑组分和矿物成熟度3种参数确定古盆地边界。
The sandy and gravelly wedges originated in the north central segment of the Longmenshan front during the Early and Middle Jurassic, and the migrated southwestwards duri.
从川西龙门山前陆盆地上三叠统—侏罗系沉积纪录可以看出 ,早中侏罗世以后整个盆地地层构型为一个板状特征 ,但在其近造山带一侧的盆地边缘又有大量的冲积粗碎屑存在 ,砂砾质粗碎屑楔形体在早中侏罗世主要位于龙门山前缘中北段 ,而晚侏罗世—早白垩世则明显地向南西方向迁移 ,盆地在不同时期、不同部位和不同成分的砂砾质粗碎屑楔形体的时空展布显示物源迁移明显 ,这是龙门山造山带走滑作用沉积的产物。
