Global Boundary Stratotype Sections and Points (GSSP)
“A Stratotype or type Section is a geological term that names the physical location or outcrop of a particular reference exposure of a stratigraphic sequence or stratigraphic boundary.” Classification of Stratotypes : GSSP (Global Boundary Stratotype Sections and Point) A GSSP is an internationally agreed upon stratigraphic section which serves as the reference section of

Soil and Soil profile
Soil is a layer produced by the gradual weathering of the rock and covers the upper most surface. Development of soil depends on the several factors like Climate, Time, Topography, Parent rock, Biological activity etc. Soil Profile : The soil profile is the sequence of soil material found in the vertical section. The development of

Sand Dunes and their classification
Sand dunes are the build up of sand formed due to water or wind process under the influence of gravity. It typically takes the shape of a ridge, mound or hill that far from the tidal influence. The area which is associated with the dunes is called dune system or dune complex. A collection of

Conventional vs Unconventional Oil and Gas
There are several types of geological formations that trap naturally occurring energy resource. They are categorized as either ‘conventional’ or ‘unconventional’ resources. Conventional Unconventional Conventional oil and gas is trapped in naturally porous reservoir formations that are capped with impermeable rock strata. When intercepted by a well, oil and gas is able to move to

Layers of the ocean
Ocean is much more deeper than the elevation of the land area on the continent. As you can imagine that the highest point in the continent is around 8800m from the mean sea level while the deepest part of the ocean is 11000m deep from the mean sea level. This deep and thick water column

Mineral Phase transition in Mantle
Mantle subdivision : In the PREM seismic model, the boundary between the upper mantle and the lower mantle is accepted at a depth of 670km, where seismic velocities and density increases. This discontinuity is related to the transition of olivine from the ringwoodite phase into the mixture of perovskite and mangnesiowustite. In the Pyrolite model,
