Abstract: The Zoige carbonaceous-siliceous-pelitic rock type uranium deposits locate at the south subzone of western Qinling Mountains, which is one of the ten largest uranium resource bases in China. However, some problems still need to be answered, such as deep exploration, resource expansion and ore genesis. The shape, occurrence and distribution for ore bodies of Zoige carbonaceous-siliceous-pelitic rock type uranium deposits are summarized according to detailed field investigation and research in recently years. These layered, lenticular and lentil ore bodies mainly occur in Silurian low metamorphic siliceous rocks, limestone and slate, and these ore bodies are controlled by lithology, structure and siliceous limestone. It is proposed that the three essential ore controlling factors are fault structure, siliceous limestone and lithological boundary. It is inferred that the superimposed mineralization and deep fluid have important role in the formation of uranium deposits of Zoige area.
