He graduated with B.A. Honours in geology from the Presidency College, Madras, in 1919, undertook post-graduate training and research with ARCS (Associate-ship of Royal College of Science) [2] Scholarship at Imperial College ...
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]
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 ...
This is a list of Global Boundary Stratotype Sections and Points.Since 1977, Global Boundary Stratotype Sections and Points (abbreviated GSSPs) are internationally agreed upon reference points on stratigraphic sections of rock which define the lower boundaries of stages on the geologic time scale.
Lathi Formation (India) The Lathi Formation is a Mesozoic geologic formation in India . Dinosaur remains are among the fossils that have been recovered from the formation.
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 outcrops near the Gangapur village was first described in 1881 as the Gangapur beds. [1] In 1969, the area was instituted as the Gangapur Formation. It was also determined that the Gangapur Formation extends from north of Nowgaon (Lat. 19°20’N; Long. 79°24’E) to the west of Gangapur (Lat. 19°16’N; Long. 79°26’E) and in the east ...
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.
