The Sukumaland greenstone belt of the northwestern Tanzania Craton is an important gold district in Tanzania Vitoria Lake greenstone belt�� Gold-bearing quartz vein is the main mineralization��and the distribution of the orebodies is strictly controlled by shear zones�� Based on the study of regional tectonic characteristics and geo- chemical characteristics��the authors conclude that the basalts in Sukumaland greenstone belt have been formed in the back-arc setting��the rhyolites and granites formed in the continental arc setting��and N--S pressional structures and E --W extensional structures are the main tectonic framework�� The metallogenic model of gold-bearing quartz vein has been eatablished��which shows that mineralized veins are concentrated in EW��SEE and NE shear zones�� and the formation of rich orebody has experienced multistage structures deformation��superposition and enrichment of metallogenic fluids��
