摘    要:桓仁—宽甸金、有色金属矿比集中区是华北地台北缘太平洋成矿带的重要成矿区。通过区域成矿地质背景和控矿因素的分析,划分了六种区域成矿类型及两大成矿系列,建立了区域多元成矿模式。沉积变质改造型铅锌、金、铜矿产受辽吉古裂谷含矿岩系中的特定层位控制,成矿物质来源于海底火山作用。中生代有色金属矿产受燕山晚期不同阶段特定岩性控制,第一阶段受张剪性断裂控制的中性、中酸性侵入岩与铜(铁)、金关系密切;第二阶段的中酸性脉岩控制部分铅锌、铜矿床;第三阶段的中酸性浅成、超浅成侵入体与铝、铅锌、铜矿有关。中寒武世地层可提供部分矿质,并成为接触交代型矿床的最佳赋矿层位。

关 键 词:桓仁—宽甸    有色金属  控矿因素  成矿系列  成矿模式

Abstract:The centralized mineralization province of gold and nonferrous metals in Huairen Kuandian region is an important metallogenic province in the Pacific metallogenic belt on the north edge of North China platform.By means of studying regional metallogenic geological setting and ore-controlling factors,it is divided into 6 types and 2 series and a regional multiple-metallogenic model is established.The paper advances that metagenetic recreation-type Pb-Zn,Au or Cu deposits were controlled by special strata of ore-bearing rock series in Liaoji palaeorift and metallogenic material came from submarine volcanism.Mesozoic nonferrous metal deposits were controlled by different rock types in different stages of the late Yanshanian period:in the first stage, intermediate or intermediateacid intrusive rocks controlled by extension-shear fractures were bound up with Cu(Fe),Au deposits:in the second stage,intermediate-acid vein rocks controlled part of Pb-Zn and Cu deposits:in the third stage,intermediate-acid hypabyssal and superhypabyssal intrusives assoiated with Mo,Pb-Zn,Cu deposits.The middle cambrian stratum provided part of minerals,especially,it was the best host bed for contact metasomatictype deposits.
Keywords:Huairen-Kuandian  Gold  NonferrOus metals  Ore-controlling  factbr Metallogenic series  Metallogenic model
