Abstract: Xuequan Cyprus-type copper(zinc)-rich massive sulfide deposits is located in the volcanic rock belt of Ordovician back-arc basinalong the west section of the North Qilian mountains.The formed deposits is controled by the spout ing center of volcanic hydrot hermal solution,and the mineralization in each spouting center obeys tometal logenic model as "mushro om" in shape.It has been found that there are numbers of the spouting center in Xuequan oredistrict,in which the ore bodies has the feature of the out croppinging roup and concentrating in block.In accordance with the topography of ore dist rict,the authors suggest that prospecting and explor ation for mineral resources in future should actupon the idea that the prospecting on whole ore district——geological survey and geophy sical prospecting should be made use of searching out hydrot hermal spouting center and exploration in spot,i.e.the adit will beutilizd to check ore body.
