沉积岩的年龄范围从二叠纪到更新世的基础上跨印度山脉的巴基斯坦。该序列超过20，000英尺厚，由20个地层和成员组成。新的名称已被提出，并为所描述的五个地层指定了模式剖面。Makarwal煤田位于Surghar山脉。含煤地层为古新世，其上覆盖着总厚度超过15，000英尺的第三纪岩石。煤是从一个单一的床，厚度范围从2英尺到超过10英尺。容易获得的煤炭曾经是该地区的主要矿产资源，现已大部分枯竭，但还有1 600多万吨未开发的储量。其他矿产资源包括储量丰富的石灰石、白云石、绿砂、玻璃砂和含铁岩石。
Sedimentary rocks ranging in age from Permian to Pleistocene underlie the Trans-Indus Mountains of Pakistan. The sequence, which is more than 20,000 feet thick, consists of 20 formations and members. New names have been proposed and type sections designated for five of the formations described. The Makarwal coal field is located in the Surghar Range. The coal-bearing strata are of Paleocene age and are overlain by younger Tertiary rocks that exceed 15,000 feet in total thickness. The coal is produced from a single bed that ranges in thickness from 2 feet to more than 10 feet. Easily accessible coal, once the principal mineral resource of the area, is mostly depleted, but more than 16 million tons of undeveloped reserves are available. Other mineral resources include abundant reserves of limestone, dolomite, greensand, glass sand, and iron-bearing rocks.
