The earliest rocks found in the Lesser Himalaya are gneisses and crystallines in which the 1860 Ma Jeori-Wangtu-Bandal Granite-gneiss Complex (JWBC) is intrusive. It forms the basement complex for the oldest Lesser Himalayan rocks and are a possible extension of the Peninsular rocks. In stratigraphic/parautochthonous position it is found only in the Himachal and J&K (Kishtwar). In the Eastern Himalaya, the basement rocks occur as tectonic slivers. Once the JWBC was cratonised there was a formation of paleosol prior to the 1800 Ma rifting. The JWBC is also involved in thrusting and forms a tectonic marker (Baragaon/Gahr) throughout the Himalaya.
