摘要
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 volcanics 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-Hamin basin was southward migration,the Harlik area become back arc setting.South of Harlik area exist northwards subducted ocean basin at Devonian-Carboniferous.
