High chemical diversity in solvent soluble polar fractions of the tissint shergottite.
Meteorit. Planet. Sci. 47, A344 (2012)
At about 2 am local time on July 18, 2011, a bright fireball was observed by several people in the region of the Oued Drâa valley, East of Tata, Morocco [1]. After it was found the meteorite was rapidly classified as a Martian Shergottite. For the specific structural characterizations of the organic matter in Martian meteorites, this freshly fallen Shergottite is of high importance because of its highly limited terrestrial contamination. Here we report on the chemical diversity of the polar fraction in the methanol extracts of different Tissint sample fractions (crust, bulk, olivine macro crystals, vitrified fractions) using high field ultrahigh-resolution mass spectrometry. This technique was recently introduced to the field of meteoritics and enabled the description of thousands of C, H, N, O, S based molecules simultaneously out of CM2 carbonaceous chondrites [2, 3] as well as out of the very recent C-type Sutter´s Mill fall [4].
