Memoirs of the Geological Survey of India.The Structural and Tectonic History of India

1953

Each of the three major arcs making up this region has its convex side facing the stable mass of the Peninsula, so that the thrusts are directed towards the south in the Himalayas, towards the east in the Baluchistan arc and towards the west in the Burmese arc. [...] The Satpura Range between the Narbada and the Tapti in Gujarat is made up of Deccan Traps and the trend is continued through the Mahadeva Hills, the Maika I Range, the Mainpat Hills and the north of the Chota Nagpur plateau to the Rajmahal region in the Ganges Valley. [...] At and near its western end the rocks of the plateau show the Satpura trend, while in much of the rest of the area the trend is that of the Eastern Ghats. [...] The Upper Gondwanas are well developed in the Rajmahal area at the head of the Ganges delta, in the Janakpur-Sohagpur area of the Son Valley, in the Jubbulpore and Pachmarhi regions in the Central Provinces, in the Godavari Valley, Gujarat, Cutch, Jaisalmer in Raj- putana and a few places along the east coast. [...] The Sylhet Traps of the Assam plateau and the lavas in the Abor Hills of the eastern end of the Himalayas, as well as the dykes of lamprophyre, periclotite and basalt which traverse the eastern coalfields, are all regarded as of the same age.
