东南亚地区地质成矿特征及找矿潜力分析

东南亚地区是地处特提斯成矿域、环太平洋成矿域交汇部位的全球重要成矿区带,其优势矿产资源铜、金、铁、镍、铬、铝、钾盐、锡、铅、锌等与我国矿产资源结构具有较强互补性;成矿类型多样,斑岩型铜金矿、中低温热液型金矿、矽卡岩型铁矿、热液-矽卡岩型钨锡矿、红土型铬镍矿、红土型铝土矿等非常发育,不少矿床为世界级矿床;成矿时代以中、新生代为主,矿产空间分布多成群成带,部分矿床聚集区为世界级巨型成矿带,岩浆岩成矿专属性特征明显。在上述特征分析的基础上,对10个具代表性的重要成矿带找矿潜力进行了概略性评价,结果显示该区仍具有较大的矿产勘查开发潜力。

Geological and Metallogenic Characteristics and Prospecting Potential in Southeastern Asian

Southeast Asia is an important metallogenic belt in the world at the intersection of Tethys metallogenic domain and Circum-Pacific metallogenic domain. Its dominant mineral resources, such as copper, gold, iron, nickel, chromium, aluminium, potassium, tin, lead and zinc, are highly complementary to China's mineral resources structure. There are various metallogenic types, such as porphyry copper-gold deposit, medium-low temperature hydrothermal gold deposit, skarn-type iron deposit and hydrothermal - Skarn-type tungsten-tin deposits, laterite-type chromium-nickel deposits and laterite-type bauxite deposits are well developed, and many of them are world-class deposits. The metallogenic epoch is dominated by Mesozoic and Cenozoic, and the spatial distribution of minerals is mostly in clusters and zones. Some ore deposit accumulation areas are world-class giant metallogenic belts, with obvious magmatic mineralization specificity. On the basis of the analysis of the above characteristics, the prospecting potential of 10 representative important metallogenic belts is evaluated. The results show that the area still has great potential for mineral exploration and development.
