| 摘 要： | 以甘肃境内所发现和勘查的133处金矿床的时空分布为基础,以含矿建造为原则,将甘肃金矿类型初步划分为7个建造（预测）类型和10个亚类型：火山岩型（海相火山岩型）、岩浆型（包括斑岩型、基性—超基性岩型、中酸性岩型、矽卡岩型）、浅变质碎屑岩型、破碎蚀变岩型、微细浸染型（沉积建造中的金矿类型）、花岗—绿岩型、砂金型,尝试性的厘定了21个金矿床式,随着认识不断深化和科学表达,矿床式（类型）的研究和厘定将更加科学,以期为金矿勘查和预测评价及找矿工作提供参考依据。

| Abstract: | In principle of the ore-bearing formation, gold deposit types are initially divided into 7 formations （prospecting） types and 10 sub-types （volcanic rock-type or marine voeanic rock-type, magmatic rock-type including porphyry-type, basie-uhrabasic rock-type, intermediate-acid rock-type and skarn-type, low-grade metamorphic clastic rock-type, structural alteration rock-type, fine disseminated type, granite-greenstone-type and placer type） in Gansu, based on the spatial-temporal distribution of 133 gold deposits being found and explorated. There are 21 gold deposit-types to be determined. With the deepening understanding and scientific expression of gold deposit-types, studying and determining of deposit-types will be more scientific, which provide the basis for exploration, prediction-evaluation and prospection of gold deposits. |
