摘要
黑龙潭金矿矿化类型以蚀变岩型及石英脉型为主,其中破碎带蚀变岩型又可分为早、晚两期。研究表明,早期破碎带蚀变岩型矿化形成于印支期,成矿物质主要来源于变质地层;石英脉型矿化形成于燕山期,成矿物质主要来源于岩浆岩;晚期破碎带蚀变岩型矿化则是前两期矿化叠加的结果。该矿床的形成即是上述三种不同时期、不同矿化类型叠加的结果。
The metallization model of the gold deopsit in Heilongtan is mainly made up of the althered rock and the quartz vein in fracture zone.And the althered rock can be divided into two parts-early and late althered rock.The research has shown that the metallization of the early-althered rock in fracture zone is formed in Indo-Chinese porosity,and the ore-forming objects come mainly from the metamorphic strata;the quartz vein is formed in Yans- ban porosity,and ore-forming objects come maingly from the magatic rock.The meallization of late-althered rock in fracture zone is the result of supraposition.The deposit is the result of the supraposition of different period and metaUization type.
