| 摘 要： | 松潘-甘孜地块位居中国西南部,北邻昆仑地块,西与青藏高原毗邻,东南缘与扬子板块相连,东北部与秦岭造山带相接.近年来,松潘-甘孜地块已成为地学界研究的焦点.我们对该区出露的碎屑沉积岩进行了地质、岩石学、常量元素与微量元素地球化学研究,结果表明该区在地质历史上长期处于大陆岛弧环境,其沉积物成熟度不高,其物源多为火成岩区.松潘-甘孜地块的物源区以扬子板块为主,在不同时代有不同火成岩物质的加入.

| Abstract: | The Songpan-Ganze block is located in southeast of China. It is joined with the Kunlun- block, Tibet Plateau, Yangtz craton, and Qinling orogeny in north, west, southeast and northeast, respectively. Recently, the Song- pan-ganzi block has been the focus of research in the geological field. Through geologic, petrologic, and geochemical study on the detrital sedimentary rocks in the block, we concluded that the block had stayed in continent island arc setting during most of its geological history. The provenance of sediments was igneous rocks mainly from the Yangtze craton. |
