摘　　要：马达加斯加苏阿拉拉铁矿为沉积变质型矿床,属硅—铁建造型磁铁矿,赋存于前寒武系地层的石英岩中。对矿床的地质特征和成矿规律进行分析,认为安巴克复式背斜控制了区内矿体分布及形态,岩浆活动影响着矿体的厚度与品位。加强对区内褶皱构造及岩体分布的研究,有望在该区取得找矿突破。The Soalala Iron Mine in Madagascar is a sedimentary metamorphic deposit,belonging to silicon-iron formation magnetite,occurred in quartzite in Pre-Cambrian strata.Based on the analysis of the geological features and metallogenic regularity of the deposit,it was concluded that the distribution and morphology of the ore body in the Ambak complex anticline were controlled,and the magmatic activity affected the thickness and grade of the ore body.It is hoped to make a breakthrough in prospecting in this area by strengthening the study of fold structure and rock mass distribution.
