Title: Rare gases in Bansur, Udaipur and Madhipura chondrites Authors: Gopalan, K. & Rao, M. N.
We have analysed three Indian meteorites - Bansur, Udaipur and Madhipura - for the elemental and isotopic composition of Ne, Ar, Kr and Xe and determined their radiation and gas-retention ages. It is found that Udaipur belongs to the group of unequilibrated ordinary chondrites and Madhipura probably belongs to the group of shocked hypersthene chondrites.
