The Geology of the Shah Dheri-Kabal area, Swat
Abstract
This paper presents a geological map and petrography of about 20 square miles of the Shah Dheri-Kabal area in the Upper Swat . The preriously undivided (? Precambrian) Hornblendic Group of Martin et al., 1962, which covers most of the area, has been divided into Homogeneous Amphibolites and Banded Gneisses,
Dioritic Rocks, Alpine Ultramafic Rocks, and Quartz Diorites and Simple Pegmatites. With the exception of the amphibolites and gneisses, the rocks are considered to be connected with the Himalayan orogeny and may be Middle Cretaceous to Early Tertiary. The amphibolites, gneisses, and dioritic rocks have generally been metamorphosed to amphibolites grade; hornblende, epidote and, in some, garnet are very common. The group has a thrust-faulted contact with the rocks of the Lower Swat-Buner Schistose Group (Siluro-Devonian or possibly Ordovican), which cover the southern most part of the area. These are represented by low grade eugeosynclinal sediments metamorphosed to phyllitic schists, marble, and greenschists.
The area is of some economic importance because of the occurrence of china clay, corundum, and magnetite (the latter to the north of the area investigated).
