Provenance of Early Triassic Hongshuichuan Formation in the southern margin of the East Kunlun Mountains: Constrains from detrital framework, heavy mineral analysis and geochemistry
东昆仑南缘早三叠世洪水川组的源区特征:来自碎屑组成、重矿物和岩石地球化学的证据

Early Triassic Hongshuichuan Formation in the southern margin of the East Kunlun Mountains is composed of shallow- marine and nonmarine conglomerate,sandstone,sihstones,shale and oomicrite,which accumulated in a forearc basin.Sandstone detrital modes,heavy mineral assemblages,geochemistry and paleocurrent data indicate that the source of the Hongshuichuan Formation predominately derived from the island-arc northward,and the A'nyemaqen ophiolite complex also provided some detritus for the Hongshuichuan Forma...
