Title: PETROGENESIS OF THE AKETESHI VOLCANIC ROCKS FROM NORTH OF THE KASHI RIVER,NILEKE COUNTY,XINJIANG
Abstract: The Aketeshi Formation volcanic rocks of the Boluohuoluo stratigraphic group outcrop on the north side of the Kashi River in Nileke County in Xinjiang.Detailed studies of the petrography,petrochemistry and geochemistry,indicate these volcanic rocks have high contents of aluminum and potassium and are intermediate to acid lavas and homoplasmic tuffs.The volcanic rocks belong to the cal-alkaline series and petrochemistry and geochemistry show characteristics of island arc volcanic rocks.This area was in an arc and rear-arc basin on convergent plates in the Middle Devonian.The tectonic environment of the Aktashi Formation volcanic rocks offers important evidence for the tectonic evolution of this area.
