Unusual chemical diversity in solvent soluble polar fractions of the Sutter's mill carbonaceous chondrite.
Meteorit. Planet. Sci. 47, A345 (2012)
On 22 April 2012, a fireball was observed over northern California, and since about 50 individual meteorites (430 g to date) were recovered in a strewn field around the Sutter’s Mill historic site [1]. Especially for the structural characterization of the soluble organic matter, this fresh carbonaceous chondrite is of high importance because of its limited contamination and the recovery of two different samples before and after a rain event. Here we report on the chemical diversity of the polar fraction in the methanol extracts of two selected samples 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 a couple of CM2 type carbonaceous chondrites [2, 3] as well as out of shergottites [4]. We analyzed 25 mg of the Henningsen-Lotus parking lot freshly fallen fragment, designated SM2 and 25 mg of the SM12 fragment that was collected after a rain event.
