A Note on Kot-Prang Ghar Melange and Associate Mineral Occurrences
Abstract
Lower Mohmand and western part of Malakand Agency are characterized by ophiolitic Late Jurassic to Cretaceous Melange Complex. Middle to Late Paleozoic metasediments, and Malakand-Kot and Silai Patti-Kolangi granitic gneisses of Cambrian age make up the rest of the rock sequence within the area. Thrust faults, intricate folds, joints, and complex foliation planes are the major structural features. These structures are the result of multiple tectonic events in this region. Gemstone and metallic ore mineralization has taken place in the Melange Complex, of which emerald, epidote, beryl, rutile, jadeite/nephrite, manganese and chromite may be of economic significance.
