Research Abstract

In-situ observations of crystallization from chondrule melts have successfully been conducted using gas get levitation method. It was found that hypercooling of 300-1100K is needed for the reproduction of various chondrule textures and the crystallization finishes within a few seconds. Based on the experimental data, a new kinetic model could be proposed for the chondrule texture formation.
