Thermochemical stability of low-iron, manganese-enriched olivine in astrophysical environments [PDF]
, 2012 Low-iron, manganese-enriched (LIME) olivine grains are found in cometary samples returned by the Stardust mission from comet 81P/Wild 2. Similar grains are found in primitive meteoritic clasts and unequilibrated meteorite matrix.
