| 摘 要： | 通过对甘肃西成地区区域地质背景的分析,将西成矿集区划分为2个成矿系列,即与泥盆纪海相沉积作用有关的铅、锌、铜、大理岩、白云岩、重晶石等矿床成矿系列和与印支-燕山期中酸性岩浆侵入有关的金、钨(钼)矿床成矿系列。通过近几年找矿成果分析、与邻区矿床成矿系列对比、含矿层的叠置关系和成矿系列的叠加复合研究,认为西成矿集区西延部位具有较好的铅锌找矿前景;西部热水沉积-改造型铅锌矿发育地段,是寻找微细浸染型和构造蚀变岩型金矿的有利地段,深部找矿空间广阔,厂坝岩体是西成矿集区钨钼找矿的突破口。

| Abstract: | Based on the analysis of regional geological background in the Xicheng area of Gansu province,the Xicheng mineralization area is divided into two metallogenic series.One is the deposit series of lead,zinc,copper,marble,dolomite and barite associated with Devonian marine sediments.The other is the deposit series of gold and tungsten(molybdenum)related with Indosinian-Yanshanian intermediate-acid magma intrusion.Through the analysis of ore-searching results in recent years,comparison with the metallogenic ser... |
