东南亚缅泰老越柬五国与中国邻区成矿带划分及成矿特征

Classification and metallogenesis of metallogenic belts in Southeast Asia and the neighbouring southwestern part of China

东南亚缅泰老越柬五国与中国西南邻区在大地构造上位于特提斯构造域东段与西太平洋构造域相交接地带,复杂的地质构造演化造就了该区丰富的矿产资源。通过近年来对东南亚中南半岛及中国邻区的地层、构造、岩浆及矿产研究,在大地构造单元划分基础上,本文将研究区划分为两个一级成矿域(特提斯成矿域、环太平洋成矿域)、3个二级成矿省(滇缅马成矿省、印支成矿省、扬子-华夏成矿省)和17个三级成矿带。并对各成矿带的地质及成矿特征进行了简单阐述。

Five countries including Myanmar, Thailand, Laos, Vietnam and Cambodia in Southeast Asia and the neighbouring southwestern part of China tectonically belong to the transitional zone between the eastern Tethyan tectonic domain and western Pacific tectonic domain. The complex tectonic evolution created the rich mineral resources in these areas. The examination of stratigraphy, tectonics, magmatism and ore deposits in Southeast Asia and the neighbouring southwestern part of China in recent years has disclosed that the study areas may be classified into two first-order metallogenic domains including the Tethyan and circum-Pacific metallogenic domains, three second-order metallogenic provinces including Yunnan-Myanmar-Malaysia, Indo-Sinian and Yangtze-Cathaysian metallogenic provinces, and 17 third-order metallogenic belts. The present paper gives a detailed description of the geology and metallogenesis in individual metallogenic belts in the study areas.
