| 中文摘要: |
| 东非维多利亚湖绿岩带区是非洲大陆第三大产金区，其南部的Sukumaland绿岩带具有优越的金成矿地质条件和巨大的金成矿潜力，发育Geita、Bulyanhulu等一系列世界级金矿床。该地区金矿工业类型以绿岩带石英脉型和BIF型为主，成矿受构造、岩浆岩与地层等条件的严格控制。本文以Sukumaland绿岩带南部的Kahama地区为实验区，在理清区域金矿成矿规律和控矿要素的基础上，通过GIS加权叠加的方法利用有限的地质、航磁和遥感数据划分了金成矿有利度。 |
| 英文摘要: |
| The Sukumaland greenstone belt is located in the south of Lake Victoria greenstone belt, where is the third gold producing area of the African continent. It possesses favorable gold metallogenic conditions and great metallogenic potential, and a serious of world-class gold deposits like Geita and Bulyanhulu. These gold deposit are mainly of the greenstone-hosted quartz-carbonate vein type and iron-formation-hosted vein type, where the gold mineralization is strongly controlled by tectonics, magmatite as well as strata. This paper selects somewhere in Kahama, the southern Sukumaland greenstone belt as an experimental area. After dissecting regional mineralizing regularity and ore-controlling factors, this paper utilizes the weighted superposition method to integrate limited geological, aeromagnetic and remote sensing data, and grades the favorability of gold mineralization. |
