The World's Deepest Borehole: Kola Superdeep Borehole

The Kola Superdeep Borehole, deepest manmade hole on Earth and deepest artificial point on Earth is located in the Pechengsky district on the Kola Peninsula in Northwestern Russia. Kola Superdeep Borehole also known as the "entrance to hell" or "well to hell". Since 1988 Kola Superdeep Borehole is deepest borehole in terms of Vertical Depth and measures 12,262 metres (40,230 Ft deep), (12.2 Km) and 23 cm in diameter.

Drilling commenced in May 1970 after 10 years of planning by Russian then USSR's Interdepartmental Scientific Council of the Earth's Interior.

CIPW NORMS CALCULATIONS

CIPW NORMS CALCULATIONS The CIPW norm is named after the four petrologists, Cross, Iddings, Pirsson and Washington, who devised it in 1931. What is a Norm and why it is needed? A norm is a means of converting the chemical composition of an igneous rock to an ideal mineral composition. It often reveals similarities in rocks that have quite different modes, or observed mineral assemblages. Some of the factors that can cause such variations are: • Disequilibrium (for example, zoned minerals or reaction rims isolating the interiors of grains) • Temperature • Pressure • Alteration • Water content (otherwise identical rocks might contain biotite, amphibole, or pyroxene, depending on water content) • Other minor constituents. For example, excess sulfur or chlorine might cause scapolite to form instead of feldspar. Boron typically causes tourmaline to form. The CIPW norm calculates mineral composition as if the magma were anhydrous (water is simply treated as a separate phase) and at low press...

FOSSILISED LEAVES FROM JURASSIC PERIOD IN JHARKHAND

 Geologists Discover Fossilised Leaves From Jurassic Period in Jharkhand Geologists have found fossilised leaves, estimated to be around 150-200million years old, in Jharkhand's Sahibganj district. A couple of 20 cm by 5 cm fossilised leaves of genus Ptilophyllum have been found in Dudhkol mountain in Taljhari area on 26/09/2020 and further excavation is underway, lead geologist assistant professor Ranjit Kumar Singh of Sahibganj PG College said. The excavation is being conducted in association with National Botanical Research Institute, Lucknow under a project of the Department of Science and Technology of the Union government. "Such leaves were consumed by herbivorous dinosaurs. Smaller fossils from Upper Jurassic to Cretaceous period were earlier found in the region. We might even find fossilised dinosaur eggs during further excavation," Singh told .

Branches Of Geology

1. Mineralogy-                       Mineralogy defined as the offshoot of geology dealing with the scientific analysis of the minerals, including chemistry, structure, physical and optical properties and its artifacts. 2. Structural Geology-                                   The   branch of geology dealing with the three-dimensional distribution of the rock and its deformational history.  3. Oceanography-                             The discipline of geology dealing with the studies of oceans and seas including their framework, physical and chemical properties, origin and its ancient history and current direction.  4. Petrology-                     Petrology is systematic studies of rocks, their origin, structure, c...
