Abstract
Gansu province have vast land,the Beishan,Qilian and Qinling orogen each undergo long term and complicated geological tectonic evolution and come into being a lot of gold deposits of differ background, differ types, differ characters and differ size.Gold deposits of Gansu are controlled by specifically stratum, lithofacies, magmatism, tectonic and metamorphoism.According to the metallogenic rules of gold deposit,Beishan(North and South metallogenic belts of Beishan), Qilian, West Qinling(North,Middle and South Qinling metallogenic belts) and Motianling metallogenic districts and seven metallogenic belts are divided in Gansu province.
