| 摘 要： | 通过对陕西以往和新发现铅锌矿资源成果的分析、总结，将陕西铅锌矿床成因类型划为四级，其中一级划为内生矿床、外生矿床、变质矿床及叠生矿床；二级划为层控矿床、区域变质矿床、沉积矿床、火山成因矿床、热液矿床、接触交代（矽卡岩）矿床及伟晶岩矿床，其中区内最重要的铅锌矿床成因类型为层控矿床，次为区域变质矿床；与主要铅锌矿床有关的成矿系列初步划分为4个矿床成矿系列组合，6个成矿系列类型，9个成矿系列，其中主要与铅锌矿床有关的成矿系列为海底热液喷流-沉积铅锌矿床成矿系列、与热水渗滤作用有关的铅锌矿床成矿系列、海底喷流沉积-热液改造铅锌铜矿床成矿系列；与铅锌成矿有关的Ⅲ级成矿区（带）有5条，有关的Ⅳ级成矿区（带）有7条，主要铅锌成矿区（带）有12条，其中铅锌重点成矿区（带）有7条，即铅硐山-黄柏源铅锌铜成矿带、银硐子-桐木沟银铅锌铜重晶石成矿带、东川-小川铅锌铜成矿带、锡铜沟-板岩镇铅锌金汞锑成矿带、赵湾-黄石板铅锌金成矿带、阳平关-朱家坝古生代铅锌钴磷海泡石成矿区和勉县茶店子-宁强青木川金银铅锌铜硫成矿带。

| Abstract: | The genetic types of lead-zinc deposits in Shaanxi province are divided into four grades on the basis of analysis of literature information about the previous and new-discovered lead-zinc resources,in which the first grade includes endogenetic deposit,exogenetic deposit,metamorphic deposit and diplogenetic deposit;and the second grade stratabound deposit,regionally metamorphosed deposit,sedimentary deposit,volcanogenic deposit,hydrothermal deposit,contact-metasomatic deposit(skarn-type) and pegmatite deposit,in which the stratabound type is the most important and the regionally metamorphosed types secondary.The metallogenic series pertaining to the major lead-zinc deposits is primarily designated as 4 groups of metallogenic series,6 types of metallogenic series,9 metallogenic series,in which the metallogenic series,mostly intimate to lead-zinc deposits,are(1) submarine hydrothermal cascade-sedimentary;(2) related to thermal water leakage;and(3) lead-zinc-copper series of submarine cascade sedimentary-hydrothermal deformation types,5 III-grade mineralized zones relevant to lead-zinc deposit and 7 IV-grade mineralized zones.There are 12 lead-zinc mineralized zones in this area,of which 7 are important.They are Qiandongshan-Huangboyuan lead-zinc-copper mineralized zone,Yindongzi-Tongmugou silver-lead-zinc-barite zone,Dongchuan-Xiaochuan lead-zinc-copper zone,Xitonggou-Banyanzhen lead-zinc-gold-mercury-antimony zone,Zhaowan-Huangshiban lead-zinc-gold zone,Yangpingguan-zhujiaba Paleozoic lead-zinc-cobalt-phosphor-sepiolite zone and gold-silver-lead-zinc-copper-sulfur zone from Chadianzi in Mianxian-Qingmuchuan in Ningqiang. |
