I am currently working on stable isotopic signatures (d13C, d18O) in fossil
bioapatite for my PhD thesis in Paris (France). I am more especially
interested in diagenetic processes that happen during fossilization of
In this respect, I am about to set an experiment of diagenetic alteration
of modern enamel and bone under controlled conditions (T°C, d13C and d18O
composition of the surrounding soil etc...). The experiment is going to
last about 6 months and I will look both isotopic (d13C, d18Oin PO4 and
CO3, d15N) and cristalline (Raman spectrometry) changes in organic and
mineral phases of enamel and bone. A rapid survey of the bibliography did
not yield any similar experiment.
Has anyone heard about such "in vitro" diagenetic alteration experiment
focussed on stable isotopes ??
Thanks in advance,
