摘要
坦桑尼亚维多利亚湖绿岩带是世界上非常有名的金成矿带,目前已发现数个世界级的金矿床。通过对ML553金矿区矿床地质特征、矿床成因的研究,认为该矿床主要为黄铁绢英蚀变岩型和含金石英脉型金矿床。矿床共分为4个矿化期、4个分带。矿床成因类型为变质—热液型金矿床。
Greenstone belt of Vitoria Lake in Tanzania is the world＇s most famous gold mineralization belt,has found several world-class gold deposits. Based on the study of geological characteristics and genesis of deposit in ML553 gold deposit,the paper considers that the deposit is mainly composed of yellow-iron sericite altered rock type and gold-bearing quartz vein type gold deposit. The deposit is divided into four mineralization periods,four zonings. The type of deposit is metamorphic-hydrothermal gold deposit.
