Polycyclic aromatic hydrocarbons in the Mukundpura (CM2) Chondrite

Soluble polycyclic aromatic hydrocarbons (PAHs) have been measured in Mukundpura (MK) CM2 carbonaceous chondrite using Gas Chromatography-Mass Spectrometry (GC-MS). The data show high yields of PAHs with the presence of 2, 3, and 4 ring polycyclic aromatic hydrocarbons along with heterocyclic nitrogen and sulfur-containing compounds. MK also shows the presence of significant amount of alkylation products. The distribution and relative abundances of PAHs in the MK are discussed in context of its petrographic grade and correlation with aqueous alteration.
