The study area is located in the western part of North Qilian orogenic belt, which is Gadaban ore field. All the deposits discovered deposits in this areawere all found occurred in the contact area zone on the northern in of the acidic volcanic rocks and basic volcanic rocks of the Daliugou-Bailiugou volcanic domeondome in the north. Analysis on the research of the geological characteristics and ore chemical compositions analysis in Gadaban deposit and Guomisi deposit are with suggested that both thedeposits consisted of double rock group, is a sign of typical submarine hydrothermal sedex, which is mainly Zn-Pb-Cu polymetallic deposit, belonging to Kuroko-type deposit. By studing geochemical study on the ore bearing volcanic rocks of Heicigou group in the mine field, shows that the formation setting of the deposit is similar to back-arc rift environment.
