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).
