通过对哈尔里克山地区火山岩岩性、岩相、岩石地球化学分析,确定研究区古生代火山岩可分为奥陶-泥盆纪钙碱性中基性火山岩建造,石炭纪为钙碱性中酸性火山岩建造,火山岩主要属钙碱性系列。岩类、岩相与岩石地球化学特征表明,本区火山岩在奥陶-泥盆纪为岛弧环境,随着吐哈盆地南缘活动陆缘逐渐向南迁移,石炭-二叠纪研究区变为弧后环境,研究区南侧存在泥盆-石炭纪向北俯冲的洋盆。%Through the analysis of volcanics’lithology、lithofacies and rock geochemistry in Harlik area,to determine the Ordovician、Silurian and Devonian volcanic rocks combination is basalts-andesites-rhyolites, the Carboniferous vol-canics combination is andesites-dacites-rhyolites, basalts-rhyolites is Permain volcanic combination .The volcanics are mainly calc-alkalic series.Based on lithology、lithofacies and rock geochemistry characteristic indicate,volcanic rocks are forming in arc island setting at Ordovician-Devonian,with the active continental margin at southern sdge of Turpan-Ha-min basin was southward migration,the Harlik area become back arc setting.South of Harlik area exist northwards sub-ducted ocean basin at Devonian-Carboniferous.
