Robert (1989) reported the presence of unusually enriched hydrogen in the insoluble HF-HCl residue extracted from two chert samples of Eocene and Pliocene ages. Since the presence of heavy hydrogen might be due to the incorporation of extraterrestrial materials, the authors desired to reexamine the same samples to isolate the D-rich components. Their experiments did not reveal any D-rich components, but the hydrogen isotope composition of the insoluble residue of the two chert samples was well within the range expected for terrestrial organic matter. They also describe a protocol that needs to be followed in the hydrogen isotope analysis of any insoluble organic matter.
