Depleted Uranium: Radioactive poison of the future war.

Pakistan may use it against India in future.  By Dr. Nitish Priyadarshi Recently I got the chance to see a film on uranium disaster. Film was based on the effect of depleted uranium used in the wars of Iraq and Bosnia. Still today many people in the world are unaware of the effects of the radioactive radiation. Information on children dying due to cancer after the war were reported and published.                                      Thousands and thousands of people, including many children, died after the war in Bosnia from the use of depleted uranium projectiles. Completely healthy people who have lived or are still living in locations were targeted missiles out of the blue they got cancer or leukemia and after a longer or shorter disease died. For the first time this scientific report on poisoning w...

Geological history and the importance of pegmatite veins.

Pegmatite veins are common in almost all the rock type in Ranchi city of India. by Dr. Nitish Priyadarshi Pegmatite, meaning “joined together,” was first applied to graphic granite sometime before 1822. Subsequently, it has been extended to refer to any abnormally coarse grained rock of overall igneous character. The term “pegmatite” was first used by a French mineralogist René Haüy but he used this term as a synonym of graphic granite. Contemporary meaning was given to the rock type in 1845 by an Austrian mineralogist Wilhelm Heidinger. Most of pegmatites are more than 1 centimeter across; grains up to a meter or two across are relatively common; and individual crystals up to several meters in greatest dimension have been reported. In any case, no matter how large the grains, most pegmatites have typical igneous rock textures. Pegmatites are associated with plutonic or intrusive rocks and were evidently formed by slow crystallization at considerable depths below the surface. Individ...
