摘要
The Carboniferous lithofacies paleogeography in Northern Xinjiang was discussed by the combination of analysis on the outcrop and well profiles of volcanic rocks.The comprehensive study of borehole data,sedimentary facies,sedimentary construction,and Paleontology combination indicates that the overall characteristic of Carboniferous paleogeography in northern Xinjiang evolved from deep sea-half deep sea facies and shallow sea facies in the Early Carboniferous to the shallow sea facies,sea-land transition facies and continental facies in the Late Carboniferous.Rock association types transited from active epicontinental island-arc volcanic rock,abysmal flysch and marine carbonate rock in the Early Carboniferous to riftogenic volcanics,terrestrial clastic,marine clastics and marine carbonate rock in the Late Carboniferous.The tectonic lithofacies paleogeography and rock associations have distinct difference in different regions between Early and Late Carboniferous.
