Rapid contamination during storage of carbonaceous chondrites prepared for micro FTIR measurements
Organic contamination (~2965 and ~1260 cm^(-1) peaks) was found on Tagish Lake (C2) and Murchison (CM2) carbonaceous chondrites containing abundant hydrous minerals by Fourier transform infrared (FTIR) microspectroscopy on the samples pressed on Al plates. On the other hand, anhydrous chondrite (Mos...
