概要介绍了中亚南天山大型金矿带的构造环境、地质特征和分布特点。中亚南天山是世界重要的金成矿带,其中发育有一系列世界级矿床。在该带中,除了剪切带型(造山型)金矿外,还有夕卡岩型、细网脉型以及爆破角砾岩型。成矿围岩是前寒武纪和早古生代浅变质岩系,成矿与二叠纪花岗质岩石密切相关,成矿流体以富CO2为特征,与矿化有关的围岩蚀变强烈发育,通常以Au,Ag,Sb,Te,As,W和Bi元素组合为地球化学找矿标志。
This paper introduces the tectonic environment, geological characteristics and distribution characteristics of the South Tianshan large gold belt in Central Asia. Southern Tianshan in Central Asia is an important gold metallogenic belt in the world with a series of world-class deposits developed. In this zone, in addition to the shear zone (orogenic) gold deposit, there are also skarn types, fine reticulate types and brecciated breccias types. Metallogenic rock is a Precambrian and Early Paleozoic metamorphic rock series. Metallogenesis is closely related to Permian granitic rocks. The ore-forming fluid is characterized by CO2 enrichment, and the mineralization-related wall rock alteration strongly develops , Usually Au, Ag, Sb, Te, As, W and Bi elements for the geochemical prospecting mark.
