Presentation Highlight
Almost a century ago, Argand (1924) had proposed a collision of India with Eurasia and the creation of Himalaya. Despite such a long history of investigation, the tectonic features of the Himalaya are not well understood to date. The Himalayan Range is generally classified into a number of broad longitudinal tectonic belts. Some fundamental issues of their stratigraphy and structure are still unresolved. Especially, there has been considerable controversy over delineating the Greater Himalayan and Lesser Himalayan belts of Nepal. The Greater Himalayan thrust sheet represents the hanging wall of the Main Central Thrust. In Nepal, the thrust sheet forms two large open folds: the Great Midland Antiform in the inner zone and the Great Mahabharat Synform in the outer part. The interplay among thrusting, erosion and folding has created a complex pattern of tectonic windows and klippen. Many contemporary authors have explained the origin of inner Himalayan tectonic windows in terms of duplexes and antiformal stacks. But most of such interpretations are based on crude stratigraphic control and poor geological maps. An attempt is made to show the discrepancies in geological mapping and to give a more realistic picture of the Nepal Himalaya.
