Fall, mineralogy and chemistry of Nathdwara H6 chondrite

摘要

We report here for the first time the composition and mineralogical studies on a new meteorite, which fell?in Dhayala ki Chappar (24°58′N, 73°48′27″E) 5?km NW of Nathdwara in south Rajasthan, India, on Dec. 25th, 2012. Mineralogical and compositional studies were carried out on a representative piece of the Nathdwara meteorite sample. The mineralogical composition of the meteorite has been found to be olivine (42?45?vol.%), feldspar (10?15?vol.%), orthopyroxene (23?25?vol.%), troilite (6?8?vol.%), and titanium bearing minerals (6?8?vol.%). Our investigations show that the Nathdwara meteorite belongs to H6 group of ordinary chondrites. Graphical abstract Display Omitted Highlights ? First report on the Nathdwara meteorite fall, Rajasthan in western India. ? Compositional studies show the stone is H6 group of ordinary chondrite. ? Olivine, pyroxenes and ilmenite compositions confirm the H6 type meteorite.
