Structure and Stratigraphy of the Northern Gandghar Range, Hazara, Pakistan
Abstract
The northern Gandghar Range comprises four structural blocks, separated by the Baghdarra, Sirikot and Darrah faults. In contrast to the southern Gandghar Range none of them shows a complete succession of stratigraphy. The stratigraphy of the northern Gandghar Range is different from that of the southern Gandghar Range in two ways. Firstly, the northern Gandghar Range has an additional stratigraphic unit, the Tanawal Formation which is completely missing from the southern Gandghar Range. Secondly, the Utch Khattak Formation which is so widely developed in the southern Gandghar Range is not found in the northern Gandghar Range.
The deformation of the northern Gandghar Range is accomplished by thrusting and associated folding. The nature of deformation of each block suggests a piggy-back style of thrusting and attitudes of folds indicate two distinct phases of deformation.
