巴基斯坦的二叠纪是众所周知的，但知之甚少。巴基斯坦是古特提斯（北方半球）的二叠纪和冈瓦纳的二叠纪同时出现的少数几个地方之一。本章将回顾代表印度/巴基斯坦板块北方部分的巴基斯坦地层。古特提斯的二叠纪位于科希斯坦岛弧带北部和东部的许多构造块体中（图1）。Talent等人（1981）总结了这些几乎不可接近的岩石的已知情况。科希斯坦岛弧带以南的几个冲断岩席中，是沿着冈瓦纳北方裂谷侧翼盆地沉积的二叠纪地层。显然，南缘（克拉通）、盆地和北方缘（裂谷翼）都保存在这些逆冲岩席中。详细的牙形石生物地层学对于更好地了解这些岩石的时间和相互之间的相关性以及与二叠纪居住在北方半球的亚洲部分地区的相关性非常重要。
The Permian of Pakistan has been well known, yet poorly understood. Pakistan represents one of the few places where the Permian of the Paleotethys (Northern Hemisphere) and the Permian of Gondwana both occur. This chapter will review the stratigraphy of Pakistan that represents the northern part of the Indian/Pakistan plate. The Permian of the Paleotethys is in many structural blocks to the north and east of the Kohistan island arc terrane (Fig. 1). Talent et al. (1981) summarize what is known of these barely accessable rocks. South of the Kohistan island arc terrane, in several thrust sheets, are Permian strata that were deposited along the northern part of Gondwana in a rift flank basin. Apparently, the southern margin (craton), basin, and northern margin (rift flank) are preserved in these thrust sheets. The detailed conodont biostratigraphy is important for developing a better understanding of the timing and correlation of these rocks to each other and to the parts of Asia that resided in the Northern Hemisphere in the Permian.
