塔里木地台(以下简称塔台)西部早二叠世的海陆界线大致在阿克苏台隆东侧,经其南缘音干山—柯坪塔格北—阿克玛特—喀什以东—莎车、叶城西—皮山河一带,此线以南、以东为陆相沉积,以北、以西为海相沉积.通过我队近年来的工作及获得的资料,笔者认为塔台西部特别是柯坪、巴楚两地区的陆相下二叠统是完全可以统一划分及对比(图1). The Tarim Basin (hereinafter referred to as the tower) in the western part of the Early Permian sea and land boundaries in the east side of the Aksu Tai Long, the southern edge of the Sogangshan - Keping Tagar North - Aktem - Kashgar - Shache, Yecheng West - Pishanhe area, south of this line, to the east of the continental deposition, to the north, west of the marine deposition.Through my team work in recent years and access to information, I believe that tower west of Taiwan, especially Keping, Pakistan The continental Lower Permian in the Chu and Chu region can be completely divided and contrasted (Figure 1).
