东南亚地区重要矿床地质特征及找矿潜力

东南亚地区矿产资源十分丰富,特别是铜、镍、铬、钾盐、铝土矿等矿产资源与中国有较强的互补性,受到中国地质学家和矿业界的广泛关注。东南亚地区总体矿产勘查、开发程度低,随着东南亚地区经济的快速发展和找矿技术方法的提高,该地区一大批新矿床的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。通过对东南亚地区产出的大型-超大型或代表性重要矿床地质特征和分布规律进行总结,对其产出环境和找矿潜力进行讨论,旨在为中国地质学家、矿业企业了解该地区重要矿床的地质特征、时空分布规律、找矿潜力和找矿模型提供有益信息,为中国地勘单位和矿业企业"走出去",在东南亚地区开展综合性找矿评价提供参考依据,同时也为在中国西南三江成矿带开展勘查找矿工作提供对比依据。

Geological characteristics and exploration potential of the important deposits in Southeast Asia

The abundant mineral resources in Southeast Asia, especially the tin, copper, nickel, bauxite, chromium and potash resources, have obvious complementarity for China''s resources, and hence have aroused much attention among Chinese geologists and mining industries in recent years. Although the exploration and development degree of mineral resources of Southeast Asia is very low, Southeast Asia is likely to 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, the reopening of a number of old mines and the improvement of exploration techniques, 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, Southeast Asia will be one of the best choices. Although Southeast Asia is still the 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 characteristics and temporal-spatial distribution regularities. Meanwhile, the geological setting, oreforming 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 Southeast Asia. To better find new mineral deposits in Southeast Asia, we should conduct more detailed researches both on regional metallogeny and on individual mineral deposits.
