摘要
柳树沟地区铜矿主要为裂隙式铜矿,铜矿体和铜矿化体严格限定于柳树沟-夏尔萨拉火山岩带内,受控于多级断裂构造.铜矿化地表分布范围广,矿化分散.通过火山岩、不同级别断裂构造及火山构造系统的研究,结合火山岩本身特征、矿石矿物特征以及铜矿石石英脉流体包裹体特征,提出了柳树沟铜矿的矿床类型为海相火山岩型铜矿床,并指出了找矿方向.
The Liushugou marine volcanic rock belt in the southern section of Western Tianshan is tectonically located in the southern margin of Saaerming Late Paleozoic island arc belt. The Liushugou fm. volcanic rocks, mainly intermediate and acid with a little basic basalt, are formed in an extension background in Middle Devonian. The copper deposit, strictly limited in the Liushugou volcanic rock belt and genetically related to the volcanic rocks, is barely a pint-sized deposit, and the mineralization is highly dispersive. The Cu orebodies and mineralized bodies are controlled by multilevel fault structures. The characteristics of the volcanic rocks, multilevel fault structures and volcanic structure, as well as their controlling to Cu mineralization, are studied. In combination with analysis on the ore-forming fluid inclusion and stable isotopes, the Cu deposit is considered belonging to marine volcanic type.
