Novel Progress of Upper Carboniferous Study in West Section of Mageti Slope, Tarim Basin

Abstract

Abstract: The correlation and study of Upper Carboniferous in west section of Megati slope show that two unconformities occur within the Carboniferous: one lies in major limestone between Nanzha formation of Permian and Xiaohaizi formation of Carboniferous, which is of distinct litho-electric feature and oil/gas-controlled process; the other lies at the top of Kalashayi formation of Carboniferous in west section of Mageti slope, being a large and regional unconformity. It is concluded that the latter is shaped by regression and tectonic movement in Late Carboniferous in Tarim basin.

Key words: Tarim basin, Megati slope, Upper Carboniferous, unconformity, petroleum potential
