Abstract: The Gold deposit of Zaozigou is hosted mainly in limestone, siltstone, argillite, shale and where igneous rocks locally appear and host also some gold. Laboratory analysis and geological map interpretation had shown that the orebodies are also located in sedimentary rocks as is in igneous rocks and the contact between these 2 types of rocks. They are found principally in high or low angle normal or reverse fault and mostly in brecciated sedimentary rocks. Through laboratory analysis the principal characteristic of the ore deposit is the presence of uranium which differentiates it from some important carlin deposits such as that of Nevada, USA. The alteration present consists mainly of silicification, argillization, carbonization and decalcification, but also chloritization, sulfidation and ferritization at different intensity. The presence of important quantity of rutile in almost all part of the deposit which occurred during the hydrothermal event suggested a magmatic contribution in the ore forming fluid.
