北极圈及邻区金属矿床地质特征、形成作用与找矿潜力

北极圈及邻区各类金属矿产资源十分丰富,其找矿勘查和开发利用历来为西方各国所关注。随着气候不断变暖和交通条件改善,该地区一大批新矿床发现和一系列新矿山的陆续建成投产必将为全球经济发展和社会进步注入新的活力。本文首次对北极圈及邻区产出的大型-超大型或代表性金属矿床地质特征和分布规律进行了总结,对它们的产出环境、形成作用和找矿潜力进行了讨论,旨在提高人们对这一特殊地区矿产资源重要性的认知水平,进而为实施"两个市场,两种资源"的全球矿产资源战略构想提供科学依据。

Geological features, ore-forming processes and exploration potential of the Arctic Circle and its neighboring region

Nickle-copper,copper(gold),iron-apatite,chromium and diamond deposits and ore spots are widely distributed in the Arctic Circle and its neighboring region(ACNR),and show considerable economic significance.Studies show that the ACNR will be one of the most important metal suppliers and resource bases in the world in the coming years.With the discovery of several world-class mineral deposits and the re-opening of a number of old mines,the metallogenic studies and mineral exploration have attracted increasing attention among the international mining communities.In carrying out the idea of "two types of mining markets and two kinds of mineral resources" in China,the ACNR will be one of the best choices.Although the ACNR is still a frontier area for exploration and mining,the present activity of exploration is very promising.For the purpose of clear understanding of the crust evolution and regional metallogeny,this paper has summarized the geological features and temporal-spatial distribution regularities.Meanwhile,the geological setting,ore-forming processes and exploration potential have also been discussed.The purpose of this study is to fill the knowledge gap of our understanding of the metallogeny of the ACNR.To better find new mineral deposits in the ACNR,we should conduct more detailed researches both on regional metallogeny and on individual mineral deposits.
