Abstract

Droplet chondrules in the Manych (L-3) chondrite include SiO2-poor barred olivine chondrules and SiO2-rich excentroradial pyroxene chondrules. The compositions of these two types were selected for a study of the cooling conditions necessary for forming partly or largely glassy chondrules. The cooling conditions observed in direct experimental analysis and predicted from an order-of-magnitude calculation are approx 1 K/min for the excentroradial pyroxene chondrule composition and approx 3000 K/min for the barred olivine chondrule composition. The large difference in cooling rates indicate that various objects in the chondrite represent a range of cooling rates.-P.Br.
