Description
'This video presents a complete traverse across the 'Himalayan' collision zone from Tibetan rocks near the Chinese border south to the foreland basin near Jhelum is exposed along the Karakorum High...way. Aspects covered include the formation of the Kohistan igneous complex, its accretion to the Asian collage in late Cretaceous times, the structures along this 'mothern suture' and subsequent generation, emplacement and associated metamorphism around the deformation (amphibolite and granulite facies) and the subsequent obduction of the arc onto the Indian continent (collision) at the onset of Himalayan mountain building are all evident from spectacular road cuts. Thrust structures, associated 'inverted' metamorphism and deformation of cover and basement lithologies (Indian) are studied in the North Hazara area while south there are good sections through non metamorphic 'foreland thrust systems' which lead down into the cannibalized foreland basin. excellent sediment assemblages in the Rawalpindi-Jhelum area provide information on deformation/thrusting rates and contain obvious mountain-derived clast fractions.'
