Abstract

Atmospheric entry of meteoroids has been reproduced in a high enthalpy facility, with basalt as a meteorite analog and an ordinary chondrite, to investigate the redox reactions triggered by interaction between the newly formed melt and the atmospheric gases under high temperature. The resulting material has been analyzed by electron microprobe, LA-ICP-MS, and X-ray Adsorption Spectroscopy (the latter to determine the oxidation state of Fe). The observations on the experimentally produced melt perfectly match those from natural meteorite fusion crusts.
