| 摘 要： | 分布于东昆仑南缘的早三叠世洪水川组系一套由砾岩、砂岩、页岩和鲕粒灰岩等浅海相和河流相沉积物构成的弧前盆地沉积组合.砂岩碎屑组成、重矿物组合、岩石地球化学和古水流综合研究结果表明,洪水川组砂岩物源主要来自于北侧的岛弧带,同时南侧的阿尼玛卿蛇绿混杂带也为其形成提供了部分物源;源区主要出露长英质岩石、变质岩和硅质岩. |

| Abstract: | 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... |
| Keywords: | Early Triassic Hongshuichuan Formation Tectonic setting of source area East Kunlun Mountains |
