摘要:
“中南半岛和西太平洋巨型成矿带铜金矿化构造环境与成矿规律对比研究”以中南半岛与西太平洋巨型成矿带为研究区域，以铜、金为主要研究矿种，在前期1:150万东南亚中南半岛和西太平洋巨型成矿带地质矿产图件编制的基础上，充分利用国际合作，系统开展资料收集，通过对老挝、泰国、缅甸、巴布亚新几内亚等国的研究区典型矿床成矿环境、控矿因素与成矿规律的研究，结合ETM+、Hyperion、ASTER多源遥感解译，深化了成果认知并出版了中英文图件；重点剖析了老挝Cu、Au矿床，在老挝阿文矿区开展了找矿示范和钻探验证并取得了很好的找矿效果；利用MapGIS、ArcGIS技术平台，编制成矿区带成矿规律图，建立不同矿种定量评价模型和东南亚重要成矿区带金铜矿床空间数据库；利用数学建模方法开展研究区的资源潜力评价，圈定老挝、缅甸、泰国、巴布亚新几内亚等研究区不同矿种成矿远景区。该数据集不仅是对已经取得的矿产资源区划和资源潜力评价工作的整理和总结，也为科学地引导国家地质“境外”找矿（“一带一路”倡议）部署工作提供理论基础。

Abstract:The Comparative Study of Tectonic Environment and Metallogenic Laws of Cu-Au Mineralization in the Indo-China Peninsula and Western Pacific Giant metallogenic belt takes the Indo-China Peninsula and the giant Western Pacific metallogenic belt as the study area and targets Cu and Au minerals. Data was systematically collected via international cooperation based on the compilation of 1:1, 500, 000 scale Geological and Mineral Map of Indo-China Peninsula and Western Pacific Giant metallogenic belt, Southeast Asia. Study results were deepened and maps in English and Chinese versions were published after studying the metallogenic environment, ore-controlling factors and metallogenic laws of typical deposits in the study area covering Laos, Thailand, Burma, Papua New Guinea, etc. and combining them with ETM+, Hyperion and ASTER multi-source remote sensing images. Cu-Au deposits mainly in Laos were analyzed, while prospecting demonstration and drilling verification were conducted in the Aven deposit area, Laos. The study achieved positive prospecting effects. Moreover, using MapGIS and ArcGIS technical platforms, maps of metallogenic laws of mineralization zones/regions were compiled, and quantitative evaluation models for different minerals and a spatial dataset of Au-Cu deposits in significant metallogenic zones/regions in Southeast Asia were developed. In addition, using the mathematical modeling method, resource potential assessment was conducted for the study area, and mineralization prospects for different minerals were delineated within the study area. This dataset is not only a summary of mineral resource zoning and resource potential assessment, but also a theoretical basis for scientifically guiding China's prospecting deployment in other countries (the Belt and Road Initiative).
