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。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 anti 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.
