摘　　要：新疆是我国重要的金属矿产资源州,具有众多金属矿种及各类成矿类型。为了深入了解新疆的金属矿矿体特性和成矿作用机制,通过地质学和地球化学方法,详细研究了新疆不同地质时代的主要金属矿床类型、矿体的地质和地球化学特征。结果显示,新疆金属矿床的成矿机理主要包括热液成矿、岩浆成矿、沉积成矿和深成物质成矿四个主要方面,同时各种成矿机理可能相互影响甚至叠加,形成独特的矿体形态和矿化特征。矿物含矿结构显微观察表明,部分矿物通过多次矿化过程共生在同一颗粒矿石中,暗示矿床形成会是一个复杂的多阶段过程。此研究的发现可为新疆本地及世界其他类似地区的金属矿勘探与矿产资源开发提供重要的科学参考。Xinjiang is an important metal mineral resource prefecture in China,with numerous metal minerals and various types of mineralization.In order to gain a deeper understanding of the characteristics and mineralization mechanisms of metal ore bodies in Xinjiang,we conducted a detailed study of the main types of metal ore deposits,as well as the geological and geochemical characteristics of ore bodies in different geological periods of Xinjiang,using geological and geochemical methods.The results show that the mineralization mechanisms of metal deposits in Xinjiang mainly include four aspects:hydrothermal mineralization,magmatic mineralization,sedimentary mineralization,and deep-seated material mineralization.At the same time,various mineralization mechanisms may interact or even overlap with each other,forming unique ore body shapes and mineralization characteristics.Microscopic observation of mineral mineral structure indicates that some minerals coexist in the same particle ore through multiple mineralization processes,suggesting that the formation of mineral deposits may be a complex multi-stage process.The findings of this study can provide important scientific references for metal mineral exploration and mineral resource development in Xinjiang and other similar regions around the world.
