Outline of Final Research Achievements

We developed a gas-levitation system embedded in ambient-controlled tube furnace in order to reproduce micro-textures of chondrules, and to constrain their formation conditions.A vertical tube furnace was used as a heating device. An inner tube was inserted into the outer tube, and a gas-nozzle was set on at the top of the inner-tube. H2+CO2 mixed gas were introduced into the both inner and outer core tubes. Levitated samples were observed by a long focal CCD camera.Using the system, we demonstrated the containerless cooling experiments for molten silicate droplets. As stating materials, natural peridotite and oxide mixture corresponding to a type IIA chondrule were used. The present results showed that porphyritic texture is possible to be formed from fully molten states. The gas levitation system developed in the present study is a powerful technique to simulate the molten-quenched texture of early solar materials.
