Köppen climate type:
Hydrothermal mineralisations in fractured quartzitic country rock in a wider area; additionally a tantalum pegmatite.
Located in NW Burundi, where alluvial gold deposits are also known.
Hydrothermal gold quartz veins, closely related to LCT pegmatites, or in auriferous iron oxide breccias. The hydrothermal deposition begins with an early oxide stage that comprises tourmaline, muscovite, magnetite, cassiterite, wolframite and rutile, followed by refractory gold and sulphides (pyrite and arsenopyrite, and traces of galena, sphalerite and chalcopyrite). Gold is intimately associated with bismuth and bismuthinite. Next, early magnetite and pyrite are replaced by coarse-grained hematite (specularite). Vein fill varies by chemical exchange with immediate host rocks. Veins in metadolerite, for example, that contains much reduced iron, display more ankerite, siderite, ilmenite, magnetite and specularite than veins hosted in metasedimentary rocks.
