Dear isogeochemists,
I was wondering if anyone has observed strong even/odd
predominance of n-alkanes between C10 and C18
(maxima for C14, C16, C18). Their d13C values of C14, C16 and
C18 cf higher plant d13C values in same samples
and appear not to be derived from phytoplankton source.
I have so far been unable to suggest a likely precursor.
Has anyone seen similar observations? or has suggestions to
a likely precursor?
cheers
Kliti
