P(論文) Possible weathering effect on the Rb-Sr system has been examined for the Allan Hills-769 chondrite (L6) by leaching experiments. The results of measurement of leachability of K, Rb and Sr with 1 N-HCl in the weathered and fresh specimens of the meteorite which had no fusion crust suggest that...
