胶东金矿分类的研究现状与自然分类探讨

Present Condition of Classification Research and Study on Natural Classification of Gold Deposit in Jiaodong Area

胶东金矿集区内已发现金矿床200余处,累计探明金矿资源储量近5 000t,是中国第一和世界第三大金矿集区。国内外学者对胶东金矿进行了大量研究,分类方案也多种多样,总体上可以归纳为3类:应用分类、成因分类、自然分类(成矿系列)。分类研究的对象从单一矿床发展到矿床组合,分类方案综合化、系统化程度越来越高。该文回顾了胶东金矿床分类研究的历史和现状,总结归纳了国内外学者对胶东金矿主要的分类方案,运用成矿系列思想对胶东金矿床分类的依据进行探讨,提出了胶东金矿床的自然分类方案,划分为1个成矿系列组合、2个成矿系列、3个成矿亚系列、9个矿床式。以期能为胶东金矿床成矿理论研究和深部找矿勘查提供参考。

More than 200 gold deposits have been found in Jiaodong gold deposits concentration area. The proven gold reserves are nearly 5000t. It is largest gold deposit concentration area in China, and the third in the world. A lot of research work has been carried out on Jiaodong gold deposits. It can be classified into application classification, genetic classification and natural classification. The objects of classification re search are from single ore deposit to ore deposit assemblage, and the integration and systematization of classification schemes are getting higher and higher. However, there is not a unified classification scheme so far. In this paper, the history and present situation of classification research of gold deposits in Jiaodong area have been reviewed, and main classification schemes of Jiaodong gold deposits put forward by scholars from the world have been summarized. As a result, a natural classification scheme for Jiaodong gold depos its has been put forward based on the idea of metallogenic series. They are divided into 1 metallogenic se ries, 2 metallogenic series, 3 metallogenic subseries and 9 deposit types. It is expected to provide some references for the study of metallogenic theory and deep prospecting in Jiaodong gold deposits.
