Dear all,
I am currently working on an organic rich clay deposit from the
Euphrates valley. AMS-dating of pollen seems to be the only way to
get any reliable age control, but as so far I did not manage to
receive sufficiently pure pollen concentrates.
The methods I have been using were: the standard methods (Faegri and
Iversen 1989) + heavy liquid separation with Sodium Polytungstate +
sieving and density solution with 1.3 sg following Vandergoes and
Prior 2003 and Newnham 2006. But still there is a lot of non-pollen
material.
Is there anybody out there who knows how to produce nice pollen
concentrates without too much other residues, or has experience with
the matter?
Best wishes
