| 中文摘要: |
| 对莫托萨拉一带不同时代地质体中不同岩石稀土元素的分布、配分、比值进行研究,并探讨它们之间的某些成因关系。从分析结果看,莫托萨拉石炭系和三叠系花岗质砾岩、砂岩系盆地周围花岗质岩浆岩的风化产物,铁锰矿与火山岩间在稀土元素方面关系不密切,奥热且克沟铜矿石与变质围岩间有较密切的关系。 |
| 英文摘要: |
| In this article, the authors analyse the original relation between different geological bodies by using REE pattern, REE cluster and ratio analysis of rocks and ores in motuosarla area. It is suggested that the Carboniferous and Triassic granitic conglomerate and sandstone come from the granities around the basin; Fe and Mn ores not closely related to volcanic rock, Cu ore in Aoreqieke Ditch closely retated to metamorphic wallrock. |
