Geological Characteristics and Metallogenic Rules of Gold deposits in the Mara-Musoma Greenstone Belt of Tanzania
摘要
Abstract
The Archaean Mara-Musoma greenstone belt in the eastern part of the Lake Victoria of NW Tanzania is an important gold ore concentration area.The main deposit types include the tectonic alteration rock type and quartz vein type which are controlled by steeply or gently dipping shear zones.Comparison of three typical gold deposits such as the Nyasirori,Rwamkoma and Nyabarundu gold mines permits to reveal the metallogenic geological conditions,alteration and ore characteristics and gold metallogenic rules of gold deposits in this area.It is suggested that the gold mineralization is closely linked with mafic volcanic-sedimentary rocks,ductile-brittle shear zones and magmatic activities.The nearly E-W trending shear zones are the primary ore-controlling structures which control the distribution of main industrial ores.关键词
