摘　　要：新疆哈密市大黄山铜镍矿床位于东天山铜镍硫化物矿床成矿带中。本文以岩相学及岩石地球化学研究理论为指导,充分收集,消化以往成果资料及相关文献,厘清大黄山基性-超基性岩体规模、形态与产状,总结岩相学特征,初步认为大黄山基性-超基性杂岩体与黄山东铜镍矿床岩体具有较高的相似性。分析岩石地球化学特征,大黄山岩体具有亚碱性基性-超基性岩特征,其主体为钙碱性系列,其成岩过程受到同化混染作用,成岩后期受到强烈的热液蚀变作用,成矿经过后期热液活动叠加。Great Huangshan Cu Ni deposit in Hami City,Xinjiang is located in the metallogenic belt of the East Tianshan Cu Ni sulfide deposit..Guided by the research theory of Petrography and petrogeochemistry,this paper fully collects and digests the previous achievements,data and related literature,clarifies the scale,shape and occurrence of the basic ultrabasic rock mass in the Great Huangshan,summarizes the characteristics of Petrography,and preliminarily believes that the basic ultrabasic complex in Great Huangshan is highly similar to the rock mass of the East Mount Huangshan Copper Nickel Deposit.According to the analysis of rock geochemical characteristics,the Mount Huangshan intrusion is characterized by subalkaline basic Ultramafic rock rock,and its main body is the calc alkaline series.Its diagenetic process is subject to assimilation and contamination,and its later diagenetic stage is subject to intense hydrothermal alteration.The mineralization is superimposed by later hydrothermal activities.
