Growth faults are faults that were active at the same time as the sediments were being deposited. Many show a Listric geometry with the fault soling out into shale horizons. They are common in areas with thick delta sequences. Growth faults can be recognized because sediments thicken into the hanging wall of a growth fault […]

Coal can produce large reservoirs of natural gas with commercial potential. Most coals of sufficient rank have generated large volumes of gas that may be trapped by adsorption. Natural gas is generated in coal beds both by biogenic and thermogenic processes. Natural Gas by Biogenic processes Gas derived from biogenic processes consists mostly of methane

Planation surface is a large surface that is flat or near flat with possible exception of some residual hills. The process by which planation surface are formed collectively called as planation and are exogenic in nature. There are many planation surfaces based on their mode of development : Peneplain (Devis) Pediplain (L.C. King), Panplain (Crickmay),

As we know that the Himalayan range which extends over ~2400 km have the largest glacial cover after the Polar regions and also it is highly sensitive. This region is also called as “Water Tower of the world”. The study of these glaciers is also important as it contributes to the major rivers like, Indus,

The Upper Assam and Purvanchal Range of the North-eastern India and its adjoining Shilong Plateau and Mikir Hills exposes a vast thickness of Cenozoic formations. The cenozoic formations were deposited over the basement of Precambrian rocks and Lower Gondwana Group. The oldest fossiliferous sequence of the region contains fossil assemblages indicating Upper Cretaceous age, which

The first hypothesized period of planetary-scale chilling or glaciation does not occur until about half-way through Earth’s history at 2.2 billion years ago during the Proterozoic era. Less than a billion years ago, Earth is believed to have experienced a severe freezing episode resulting in what has been called ‘Snowball Earth’. 1st Snow Ball Earth
