巴基斯坦苏来曼地区上新统的多克帕坦组是著名的西瓦利克岩系（Ｓｉｗａｌｉｋｒｏｃｋｓｅｒｉｅｓ）的中部岩性段，它由一套灰白、灰黄色的含砾中粗粒岩屑砂岩、长石岩屑砂岩和灰黄、棕红色的粉砂岩、泥岩组成，呈稳定的南北向展布。岩性上，砂岩的石英含量为３８％－５２％，长石为１１％－２９％，岩屑为２７％－５０％，以石英含量少、岩屑含量高为特征。通过岩石的颜色、有机质含量、沉积构造和粒度概率曲线图判别，这套岩石形成于干旱－半干旱气候下高流量、高流态、高负载的砂质辫状河的冲积环境。物源分析结果表明：多克帕坦组的物源主要是由造山带蚀源区所提供，即来源于一直处于隆升阶段的喜马拉雅山褶皱带。
The Upper Pluton Formation in the Suleiman region of Pakistan is the central lithological segment of the well-known Siwalikrockseries that consists of a set of greyish, greyish gravel-bearing coarse-grained lithic sandstone, Rock debris sandstone and gray-yellow, brown-red siltstone and mudstone, showing a stable north-south distribution. Lithologically, sandstone has a quartz content of 38% -52%, feldspar of 11% -29% and cuttings of 27% -50%, characterized by low quartz content and high cuttings content. Judging by the rock color, organic matter content, sedimentary structure and particle size probability curve, the rock is formed in the alluvial environment of sandy, braided, high-flow, high-flow and high-load arid-semiarid climate. The provenance analysis shows that the source of the DOPPAN group is mainly derived from the eroded area of the orogenic belt, that is, from the Himalayas fold belt which has been in the uplifting stage.
