摘要
新疆北准噶尔成矿带位于哈萨克斯坦-准噶尔板块北缘北准噶尔晚古生代沟弧带,是新疆重要的铜、镍、铁、金、钼等多金属成矿带,共划分出2个Ⅳ级矿带。通过对该成矿带地质矿产特征的总结,从矿带中矿床的时间、空间、矿床类型及规模的分布规律入手,分析成矿规律。成矿带中矿床主要形成于晚古生代,矿床类型以岩浆作用为主。中下泥盆统托让格库都克组,中泥盆统查干山组、巴尔雷克组和下石炭统姜巴斯套组是带内Au,Cu,Fe的重要赋矿层位。铜镍矿与基性-超基性岩体密切相关,卡拉先格尔断裂与额尔齐斯断裂带交汇处是寻找成型矿床的有利部位。
The north of Junggar metallogenic belt is located in the northern Junggar late paleozoic gully arc belt at the northern margin of the Kazakstan-Junggar Plate,it’s an important polymetallic metallogenic belt in xinjiang,such as copper,nickel,iron,gold and molybdenum,are divided into two levelⅣore belt.Based on the summarization of the geological and mineral characteristics of the ore-forming belt,the ore-forming rules are analyzed from the distribution rules of the time,space,type and scale of the ore deposits in the ore-forming belt.The ore deposits in the metallogenic belt are mainly formed in late Paleozoic,the type of deposit is mainly magmatism.Middle and Lower Devonian Tuoranggekuduke Formation(D1t),Middle Devonian Chaganshan Formation(D2c),Baerleike Formation(D2b)and Lower Carboniferous Jiangbasitao Formation(C1j)are important ore-bearing strata of Au,Cu and Fe in the belt.Copper-nickel ore is closely related to basic-ultrabasic rock masses.The intersection of Kalaxiange Fault and Erqisi Fault zone is an advantageous place to look for forming deposits.
