At the suggestion of Cyril S. Fox of the Geological Survey of India (GSI) he decided to work on a book on Indian stratigraphy. This resulted in the publication of Geology of India and Burma in 1943 and the Introduction to Geology of India in 1944. The first book has gone through 6 editions and has also been translated into Russian.
A 1984 Indian postage stamp showing Dr. D. N. Wadia and the Wadia Institute of Himalayan Geology, Dehradun in the background. [1] Darashaw Nosherwan Wadia FRS (23 October 1883 – 15 June 1969) was a pioneering geologist in India and among the first Indian scientists to work in the Geological Survey of India. He is remembered for his work on ...
Due to continental drift, the India Plate split from Madagascar and collided with the Eurasian Plate resulting in the formation of the Himalayas.. The earliest phase of tectonic evolution was marked by the cooling and solidification of the upper crust of the earth's surface in the Archaean Era (prior to 2.5 billion years) which is represented by the exposure of gneisses and granites especially ...
The Northern Indian State Himachal Pradesh is located in the Western Himalaya (Fig. 1). It has a rugged terrain, with elevation ranging from 320m to 6975m. [ 2 ] Rock materials in the region are largely from the Indian craton , [ 3 ] and their ages range from the Paleoproterozoic to the present day. [ 4 ]
The Intertrappean Beds are a Late Cretaceous and early Paleogene geologic unit in India. These beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. They consist a number of different subgroups and formations, and span the Cretaceous–Paleogene boundary. [2] [1]
The stratigraphic succession of the western sub-basin shows virtually complete lithostratigraphic succession from Early Cretaceous to Recent sediments. The western sub-basin portion belonging to West Bengal is characterized by gentle eastward slopes and numerous step faults with small displacements.
Commonly used geological evidences include stratigraphy, sedimentology and paleomagnetic data. Stratigraphy and sedimentology indicates the transfer of materials from one continent to another when two continents, meet, as well as the change in depositional environment after the oceanic basin is closed and sea water is completely expelled.

Khadg Singh Valdiya (20 March 1937 – 29 September 2020) was an Indian geologist [3] and a former vice chancellor of Kumaon University, internationally recognized for his path-breaking work in the fields of geodynamics and Environmental Science.
