新疆西天山西段位于哈萨克斯坦 -伊犁板块的东南部边缘 ,包括伊犁石炭纪裂谷、那拉提地块、哈尔克早古生代被动陆缘褶皱带。主要已知矿床 (点 )按其容矿围岩可分为镁铁 -超镁铁岩型、斑岩型、花岗岩型、矽卡岩型、陆相火山岩型、陆相沉积岩型、浅变质含碳碎屑岩型。根据区内成矿地质条件、矿化特征 ,区内以找金矿主 ,兼顾铜镍矿等。金矿以穆龙套型和火山岩型金矿为主 ,同时注意卡林型和中 -酸性侵入岩内外接触带型 ;铜矿以镁铁 -超镁铁岩型和火山岩型为主。地质与成矿条件与中亚成矿域具有可比性 ,因此 ,新疆西天山西段金铜成矿带应为中亚成矿域东延部分
The western section of the western Tianshan Mountains in Xinjiang is located on the southeast margin of the Kazakhstan-Ili plate, including the Ili Carboniferous rift, the Nalati block and the early Holocene passive continental margin fold belt. The main known mineral deposits (spots) can be divided into mafic-ultramafic type, porphyry type, granite type, skarn type, continental volcanic type, continental sedimentary rock type, superfine metamorphic Carbon clastic rock type. According to the regional geological conditions of mineralization and mineralization, the gold miners in the area are taken into account and the copper-nickel ore is given consideration. The gold mines are dominated by the Murong tectonism and volcanic type gold deposits, with attention paid to both the Carlin-type and intermediate-acidic intrusive types. The copper deposits are dominated by mafic-ultramafic and volcanic types. Geology and metallogenic conditions are comparable with the Central Asian metallogenic domain. Therefore, the gold-copper metallogenic belt in the western section of the Western Tianshan Mountains in Xinjiang should be the eastward extension of the Central Asian mineralization
