NEOGENE DEFORMATION OF SIWALIKS AFFECTED BY THE DELHI-HARDWAR RIDGE AS SEEN IN SATELLITE DATA, INDIA

The Siwalik ranges east of Hardwar exhibit deformation pattern not aki n to the general deformation trend of the Siwaliks elsewhere in the we stern Himalaya. Satellite image (IRS-LISS-II) of the region displays r emarkably deformed Siwalik in this region. The deformation pattern rev eals that these structures might have been primarily caused by the Del hi-Hardwar ridge. There has been compressional tectonics which were ge nerated due to westward thrusting movement of rocks across the N-S tre nding Mithawali thrust and obstruction by the shallow buried NNE trend ing Delhi-Hardwar ridge.
