中国北方岩金矿床成因类型及利用现状

Minerogenetic Types and Utilization Status of Hard Rock Gold Deposits in Northern China

对中国北方岩金矿床成因类型做了划分，并按其分布集中的区域划分为嘉荫—鹤岗，延吉—鸡西，辽吉东部，冀北—辽西和阴山—白乃庙等五个金矿成矿带，对其中的沉积变质，变质热液，岩浆热液及火山、次火山热液型等典型金矿的矿床地质特征及矿石组成进行了研究，对矿石利用现状及远景做了讨论．

The Minerogenetic types of hard rock gold deposits in northern China are classified. According to the distribution, five gold minerogenetcic belts are divided: Jiayin-Hegang, Yanji -Jixi, eastern Liaoning and Jilin, norther Hebei, western Liaoning and Yinshan - Bainaimiao. The geological characteristics and ore composition of such typical gold deposit as sedi mento - metamorphic, metamorphic hydrothermal, magmatic hydrothermal and volcanic, subvolcanic bydrothermal types are studied in detail. The present and future status of ore utilization is discussed.
