This study examines the geological features of the Lansdowne area in the Garhwal Lesser Himalaya. Age of the rocks are Precambrian to Paleozoic. The Lansdowne region showcases intricate geological features, encompassing various stages of deformation, and notable compositional changes from granite-to-granite gneiss and augen gneiss. Detailed field analyses of the rock formations and geological structures suggest significant tectonic movements which are marked by the presence of fault, joint sets, and fault gouge zones. The lithological variation in the rocks to understand the different tectonic activities and metamorphism in the area. The central part of Lansdowne, which is characterized by porphyritic granite, shows less intense deformation. This study highlights the importance of geological structure of the thrust area. The shear sense indicators determine NW-SE direction of the rocks and transportation of the area along SE direction along the Lansdowne thrust.
