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.
