摘要
香炉碗子金矿床岩石和矿石的稀土元素特征表明，爱林东山、爱林西山、烟囱桥子、荷包褶子燕山期次火山隐爆角砾岩体（脉）及霏细岩脉形成于同一次火山活动和相同的岩浆来源，成矿与太古代变辉绿岩脉和燕山期次火山隐爆角砾岩体（脉）、霏细岩脉关系密切，提供了成矿物质来源。
he REE geochemical characteristics of rocks and ores for the Xiangluwanzi gold deposit show that the Yanshanian subvolcanic cryptoexplosion breccias (veins) and felsite veins in the Ailindongshan,Ailinxishan,Yancongqiaozi and Hebaozhezi areas were formed in the same subvolcanic movement and the same magmatic source.The ore-forming process could be related closely to the Archeozoic metadiabase veins and Yanshanian subvolcanic cryptoexplosion breccia veins,felisite veins.They are considered as the ore-forming materials source.
