| 摘 要： | 概述了含矿碱性花岗岩产出的地质背景，含矿岩体的主要特征。根据岩石中暗色矿物与主要成矿元素的关系，将碱性花岗岩矿床划分为３种矿化类型：含Ｎｂ（Ｓｎ）黑云母花岗岩；含Ｎｂ（Ｓｎ）、ＨＲＥＥ钠铁闪石－钠闪石花岗岩；含ＬＲＥＥ霓石花岗岩，并指出，碱性花岗岩矿床在我国北部边区和攀西裂谷带具有良好的成矿前景。

| Abstract: | This paper summarized the geological setting of the ore-bearing alkaline granite and main characteristics ofore-bearing intrusions. According to the relationship between the darkcolored minerals and main minearalizationelements in the rocks,the deposits related to alkaline granites can be classified into 3 mineralization types,thefirst related to Nb(Sn)-bearing biotite granite, the second to Nb(Sn ), HREE-beraing arfvedsonite-riebeckitegranite and the third to LREE-bearing aegirine granite. It is pointed out that alkaline granite deposits would bebetter prospective in the northern margin of China,and Panxi Rift Belt in Shichuan province. |
