摘要: 通过麦盖提斜坡西段上石炭统对比研究发现,该区石炭系内部存在两个重要的不整合面:一个不整合面位于二叠系南闸组与石炭系小海子组大套灰岩内,该不整合面在覆盖区不仅具有明显的岩电特征,而且还具有重要的控油作用;另一个不整合面在麦盖提斜坡西段石炭系卡拉沙依组顶部,是一个大的区域不整合面,推测该不整合面是受晚石炭世海退作用及构造运动共同影响的结果。

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
