title: Isotopic characteristics of simulated meteoritic organic matter: 1--Kerogen-like material.
abstract: Carbonaceous residues from a variety of laboratory syntheses yield release patterns for C and H isotopes during stepwise combustion that fail to mimic the striking patterns characteristic of meteoritic kerogen-like residues that otherwise superficially resemble them.  It seems likely that the meteoritic material comprises a complex mixture of substances having different origins and/or synthesis conditions.
