Additional information

Crystals serendipitously discovered in inclusions of (supposedly amorphous) impact glasses from a famous meteorite impact in Tasmania 800,000 years ago, determined unambiguously to be carbonaceous by "Total-IBA" methods (self-consistent treatment of multiple Ion Beam Analysis spectra), and elucidated by sophisticated TEM. Gas chromatography shows biomarkers representative of plant species in the target ecosystem are preserved: first report demonstrating that organic materials can survive such high impact events, proving that organic molecules known to be present in meteors could contribute to the genesis of life on earth.
