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

Abstract：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.
