摘要
坦桑尼亚维多利亚湖绿岩带位于坦桑尼亚西北部,为新太古代花岗—绿岩地体,是坦桑尼亚克拉通的重要组成部分。维多利亚湖绿岩带地层主要基底为多多马系;中下部为尼安兹系;最上部为卡维龙迪系。笔者通过现有资料对该区域绿岩带金矿带地质特征及成矿规律进行分析,认为维多利亚湖地区绿岩带金矿床主要受地层和断裂及脆性—韧性剪切带控制,绿岩带在空间上也有一定分布绿律。
The Victoria Lake Greenstone Belt in Tanzania, located in the northwest of Tanzania, is a Neoarchean granitegreenstone terrain and an important part of the Tanzanian craton. The main basement of the Victorian Lake Greenstone Belt is the Dodoma System;the middle and lower parts are the Nianz System;and the upper part is the Caverondi System. Based on the analysis of the geological characteristics and metallogenic regularity of the greenstone belt gold deposit in this area, the author holds that the greenstone belt gold deposit in Victoria Lake area is mainly controlled by strata and faults and brittleductile shear zone, and greenstone belt also has a certain spatial distribution green law.
