摘要

摘要: 雪泉塞浦路斯型富铜(锌)块状硫化物矿床地处北祁连山西段奥陶纪弧后盆地火山岩带内,矿床的形成受火山热液喷流中心控制,每个喷流中心的成矿遵循"蘑菇"状的成矿模式,目前已发现矿区存在多个热液喷流中心,与此相对应的矿体表现出呈群出现,分段集中的特点。结合矿区地形特点,笔者提出矿床下一步的找矿勘查应按照"面上展开——利用地质测量、物探扫面进行探寻热液喷流中心;分段深入——在每个热液喷流中心主要利用硐探工程进行探矿验证"的思路开展工作。

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.
