摘　　要：坦桑尼亚邦达地区位于马拉—穆索马太古宙绿岩带火山岩层剪切构造带上,变质变形作用发育,岩浆活动强烈,已发现多个金矿床(点),具有很好的找矿前景。笔者阐述了坦桑尼亚邦达地区PL8077金矿矿区和矿体地质特征,分析了控矿地质条件,为后期坦桑尼亚北部剪切构造蚀变型金矿成矿规律认识和找矿勘查提供基础地质资料。Bangda area in Tanzania is located in the shear structural belt of volcanic rocks in Mala⁃Musoma Archean greenstone belt,with well⁃developed metamorphism and deformation and strong magmatic activity.Many gold deposits(spots)have been found,which has a good prospecting potential.This paper expounded the geological characteristics of PL8077 gold deposit and ore body in Bangda area,Tanzania,and analyzed the ore⁃controlling geological conditions,so as to provide basic geological data for understanding the metallogenic regularity and prospecting exploration of shear⁃structure⁃altered gold deposit in northern Tanzania in the future.
