The Geology of the Gandghar Range, Dist. Hazara, N.W.F.P.
Abstract
The Gandghar Range is located on the western tip of the Hazara district. Due to its isolated position it could attract a few geologists during the past. In the Geological Mop of Pakistan (1964), the Range is partly mapped as Precambrian and partly Silurian-Devonian.
The Gandghar Range exposes a suite of metasedimentary sorck, comprising of slate, phyllite, phullitic-slate, schists, quartzite, and crystalline limestone. five lithological units are differentiated wich have been correlated with the Palaeozoic sequences of the southern Hazara and hte Attock-Cherat Range. The oldest unit is the Mohat Nawan Limestone and the youngest is the Pirthan Limestme which are respectively homotaxial to the Shahkotbala Formation of the Attock-Cherat Range and the Sirban formation of the Abbottabad Group in the southern Hazara. The former is placed in the Upper Ordovician - Lower Silurian and the latter in the Permo- Carboniferous.
