摘要
以构造动力学体制、成矿机理和含矿建造等为原则,将东天山中段铜金成矿系统划分为晚泥盆世—早石炭世板块碰撞体制下的大南湖—头苏泉岩浆热液金铜、早石炭世板内伸展体制下的阿齐山—雅满苏火山热液铜铁和早二叠世陆内造山体制下的康古尔塔格韧性剪切铜金三个成矿系统。以成矿系统的研究内容和方法为指导,阐述了各成矿系统的地质背景、成矿系统的时空特征、控制因素、成矿系统要素、典型矿床的剖析或成矿系统内各矿床特征的对比,建立了各成矿系统模型,并总结了成矿系统的演化过程和演化谱系。
According to rules of the tectonic dynamics regime, ore forming mechanism and ore bearing formation, this study classifies the Au-Cu deposits in middle section of Eastern Tianshan into three metallogenic systems, such as, Dananhu Tousuquan magmatic hydrothermal Au-Cu metallogenic system under the plate-collision tectonic regime in the Late Devonian, Aqishan-Yamansu volcanic hydrothermal Cu-Fe metallogenic system under the plate-extending tectonic regime in the Early Carboniferous, and Kangguertage ductile shear Cu-Au metallogenic system under the intraplate orogeny in the Early Permian. Guided by the research contents and the method of metallogenic system, this study expatiates the geological setting, time-space distribution characteristics, ore-forming controlling factors, typical deposits characteristics or comparison, and the essential elements of every metallogenic system, sets up the metallogenic model, and summarizes the evolutionary process and pedigree of the metallogenic system in the study area.
