Dear All, I wonder if anyone can supply (or direct towards) me data on del c-13 (pdb) of mesozoic (triassic to cretaceous)carbonate rocks of southern Turkey. I guess data on carbonate rocks of similar age in Israel, Egypt or neighboring countries would also work as they originate from the same basin. The data is required to correct c-14 of groundwater for age-dating purposes. Thanks in advance. Dr. Serdar Bayari Hacettepe University Dept. of Geology Beytepe 06532 Ankara-Turkey
