摘　　要：阿吾拉勒陆相火山岩的岩石学、地球化学等方面研究表明,本区火山岩为双峰式组合特征,岩石化学特征表现为富碱质的弱碱性系列,属陆内裂谷构造环境。火山岩普遍含钠长石,系深部富碱岩浆分异演化的产物。火山活动与铜矿关系密切。By studying the petrology and geochemistry of continental volcanic rocks in Awulale area, the rocks are of bimodal volcanic rock composition features and belong to alkali-riched, calc -alkaline rock series formed incontinertal rift tectonic environment. The volcanic rocks are the products of deep alkali-riched magma differentiation and contain albites. The copper mineralization had intimately relation with volcanic activity.
