Jurassic sedimentary transformation event recorded by detrital components in the middle part of western Sichuan

Sandstone is the direct record of mountain uplift in the basin,and its detrital components have a good effect in analyzing orogenic belts and tectonic setting of sedimentary provenances.Jurassic sediments were systematically investigated with four main methods,i.e.,features comparison in detrital components,vertical evolution characteristics of detrital components in single well,Dickinson chart and evolution characteristics between Q/(F+L) and...
