This research documents the analysis and interpretation of selected Carbonaceous Chondrites (CC) including Murchison,
Allende, NWA 3003, Dhofar 735, Orgueil, Tagish Lake and Vigarano using organic petrology, scanning electron microscopy,
and petroleum geochemistry. The kerogen microstructures and bitumen within CCs closely resemble remnant 2.5 Ga
terrestrial microbial-like structures and their biodegraded components and solid bitumen. In both instances, organoclasts are
associated with framboidal iron sulfides or oxides and clay-like minerals. The organic-rich kerogens within three CCs
(especially Murchison) might have served as petroleum source rocks for the early generation of hydrocarbons. The maturity
varies between 0.7% (Orgueil) and 1.24% (Murchison), to 5.1 % Ro (Vigarano) with predicted maturation temperatures of
100° to 475°C. Geochemical analysis of selected CCs (Murchison, Orgueil, and Tagish Lake) reveal the organic richness and
the presence of low molecular weight n-alkanes (C10 to C20), complex cyclo-and isoalkanes, nonhydrocarbons, elemental
sulfur with abundant aromatic compounds, most of them similar to bacterial and algal derived petroleum products. Apart from
the concept of panspermia, the data highlights that three CCs sustained a formation temperature (<200°C) capable of
supporting bacterial growth in a cooler early Solar System environment. In effect, the information encoded within these
extraterrestrial sediments represents a cosmic analogue to terrestrial geopolymers and bitumen that may include some crude
oil biomarkers. Therefore, the authors propose a model of a "universal unconventional petroleum system", which implies a
prospect of oil and gas within the Martian environment and elsewhere within the Solar System.
