摘　　要：西天山造山带位于中亚造山区南部，北邻哈萨克斯坦-准噶尔古板块，南邻塔里木古板块，由古生代陆缘岩系、洋壳残片和微陆块结晶基底组成，为一典型的古生代增生造山带，由增生杂岩、微陆块等拼贴增生而成。其构造演化与天山洋盆演化密切相关，该带地质构造复杂，成矿独特，是斑岩铜金矿、黑色岩系金矿、火山岩型铁矿的矿集区带。通过境内外对比研究，认为在中国境内的伊犁盆地南部、北部、塔里木北缘等地区可能存在早古生-晚古生代的斑岩铜-金矿、火山岩型金-铜矿的成矿。在伊犁盆地中部的乌孙山、阿吾拉勒山等地区为晚古生代的火山岩型铜、铁矿集区。中天山和南天山是寻找碳质页岩型、韧性剪切带型金矿的重要地区。The western Tianshan Mt is located in the Central Asian Orogenic belt,is adjacent to the north of Kazakhstan- Junggar ancient plate,south of Tarim paleo plate, composed of Paleozoic continental rocks,the relic of the ocean crust and micro continental blocks for crystalline basement.It is belong to typical Paleozoic accretionary orogenic belt,accre- tionary complex, micro continental blocks and collage hyperplasia.The tectonic evolution and Tianshan oceanic basin evolution is closely related to the band,complex geological structure,ore is unique, including porphyry copper,black rock series gold,volcano rock type iron et al.By comparing the domestic and foreign research,consider that the southern and northem of Yili basin,northern Tarim area may exist in Early Paleozoic-Late Paleozoic porphyry copper, gold and volca- no rock type gold, copper mineralization.Wusun Mt and Awulale Mt of the central of Yili basin as the late Paleozoic vol- cano rock type copper, iron ore concentration area.The central and northern Tianshan Mt is the typical zone of seek for the carbonaceous shale type,ductile shear zone type gold deposit.
