| 摘 要： | 内蒙古阿尔山大石沟中出现一套石英砂岩,其颗粒成分石英占86%～88%,将石英砂岩和现代不同构造环境海底砂的平均碎屑矿物组合模式比较得出石英砂岩物源区为克拉通内陆块,通过QFL和QmFLt判别图解的进一步验证,物源区为克拉通内陆块。

| Abstract: | A set of middle Devonian quartzose sandstone was found in Aershan Inner Mongolia.The quartzose sandstone has has been proven to be lagoon sandstone by grain composition and sedimentary structure.Comparison of detrital modern of quartzone sandstone form Aershan area with those of modern sea-floor sands from different tectonic settings, obtain a conclusion that the provenance of quartzose sandstone is craton interior landmass.It aslo can be proven by QFL and QmFLt discriminative diagrams. |
