摘　　要：日乌多铅锌矿床位于雅鲁藏布江结合带和班公错-怒江结合带之间的拉达克-冈底斯弧盆系之隆格尔-工布江达复合岛弧。矿区出露地层主要为前二叠系松多岩群马布库岩组(Anpm)。地层岩性以浅灰色石英岩、石英片岩为主,夹少量的千枚岩。本文通过介绍区域地质背景、矿区地质特征、矿体特征及成矿作用,认为日乌多铅锌矿床主要受断层构造控制;并对其成因机制进行了初步分析,推测其应属充填热液脉型。Riwuduo Lead-Zinc Deposit is located in the composite island arc of the Ladakh - Longuel of The Gangdise arc basin system - Gongbujiangda between the Yarlung Zangbo- suture zone and Nujiang junction zone. The exposed strata in the ore is mainly the pre Permian Songduo litho group Mabuku litho formation. The stratigraphic lithology is dominated by light gray quartzite and quartz schist with a small amount of phyllite. By introducing the regional geological background, geological characteristic, ore body features and mineralization, it is believed that the Riwuduo lead - zinc deposit is mainly controlled by fault structure. And it is speculated that the deposit is of filling hydro- thermal type after analyzied preliminarily the genetic mechanism.
