| 摘 要： | 通过对云南个旧锡铜多金属矿集区内与成矿关系密切的玄武岩、花岗岩以及不同类型的矿石、围岩的研究,并进行了有关稀土元素地球化学参数的计算,对原始测试数据进行球粒陨石标准化后,分别建立了各种岩石、矿石的稀土元素配分模式。并对印支期的玄武岩、燕山中晚期含锡花岗岩和围岩等进行稀土元素特征分析与研究,认为个旧不同类型矿体稀土元素分配特征与其相关的围岩之间具有一定的继承性,矿集区的成矿物质来源具有多元和多期叠加的成矿特点。

| Abstract: | From studying on the basalt, granite and different types of ores and wall rocks which have close relations with mineralization, in the Gejiu Tin-Copper polymetallic ore concentrating region in Yunnan Province,and calculating the related geochemistry parameter of the rare earth elements(REEs), REE patterns of all kinds of rocks and ores after chondrite-normalizing are established. The REE distribution characteristics of the basalt of the Indo-Chinese epoch and tin-bearing granite of mid-late Yanshanian period are analyzed. It is concluded that the characteristics of rare earth element distribution in different types of ores are associated with wall rock in the inheritance. The sources of ore minerals in the ore concentrating region show characteristics of multi-phase mineralization. |
