Most common is the breakdown of the heavier (C<sub>15+</sub>) fraction into saturated hydrocarbons (saturates), aromatic hydrocarbons (aromatics), lighter nonhydrocarbons (NSOs [nitrogen, sulfur, oxygen], [[polar]]s, or [[resin]]s), and heavier nonhydrocarbons ([[asphaltenes]]). Oils with terrestrial input often have high saturate/aromatic ratios, whereas those from [[carbonate]] sources have low saturate/aromatic ratios and high content of nonhydrocarbons. Saturate–aromatic ratios probably increase slightly with increasing maturity and decrease with [http://www.oiltracers.com/services/exploration-geochemistry/oil-biodegradation.aspx biodegradation].
