With special reference to Jharkhand State of India . By Dr. Nitish Priyadarshi. Palaeoclimatology, the study of climates during the geological past, is one of the most topical areas research in the geoscience at present. The threat of future climate change caused by higher levels of greenhouse gases, which would drastically alter many aspects of our environment, has prompted much research to try to understand how our complex climate system works. Only by understanding how climate has evolved over million of years can we identify important cycles with a frequency in excess of the short climate records we possess. These climate cycles have the potential to have a profound effect on our environment. The determination of past climate parameters by the use of paleohydrologic conditions is an important phase of paleoclimatology. The present climate of any local area, on any continent, and around any lake basin, depends on the same factors which controlled Pleistocene climate. The study of p...
Are we heading towards the same disaster? By Dr. Nitish Priyadarshi The Eocene was much like the garden of Eden. 56 million years ago a mysterious surge of carbon into the atmosphere sent global temperatures soaring. In a geologic eyeblink life was forever changed. Climate change is changing the world. Either it is in the form of temperature rise or in the form of severe floods. Many times question arises in my mind whether this climate change is the out come of present human activities on the earth or it has happened in early geological ages too. Answer is “yes” climate change has occurred several times from the beginning of the earth formation. Evidences are preserved in from of rocks, sediments, and fossils. Studying the records of past climate change will fill you like reading thriller novel in which every chapter is full of suspense and thrill. Every chapter of this novel denotes different geological periods with different stories of climate change. My article is about the chapter...
Assessment of helium reservoir may be under taken in the Jharkhand state. By Dr. Nitish Priy adarshi. Fig: The above pictures are of Surajkund area in Hazaribag district in Jharkhand. Rocks of Jharkhand State in India which are mineral rich can also be used for trapping Helium deposit. In Jharkhand helium has been reported in the gases of different thermal springs of Hazaribag district. In Jharkhand, concentration of helium is highest in thermal gases of Surajkund (3.63 mole %) followed by Charhi (3.38 mole %), Duari (2.95 mole%), Barkagaon (0.29 mole %)and Badam (0.09 mole %). Surajkund hot spring (also called Surya Kund) is a natural hot spring in Belkapi gram panchayat of Barkatha community development block in Barhi subdivision of Hazaribag district in the Indian state of Jharkhand. Mineral radioactivity plays an important role in the natural occurrence of helium. Helium is an end product of radioactive decay. Helium is also known from the damp of many coal mines. The release of he...
