Dear all, I am a Ph D student in analytical chemistry and I know very few things in geochemistry. I did some measurements of Sr isotope ratio in wine, and I am now trying to understand the link with soil. Can anybody help me to find value of Sr isotope ratio or maybe nature or age of the soil of : - Lontue Valley, Chili, - San Joaquin Valley, Monterey county, California, USA, - Hunter Valley, Victoria, South Eastern, Australia, - Western cape, South Africa. I thank you very much for your answers, Mireille. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<< LCABIE CNRS UMR 5034 Hélioparc Pau Pyrénées 2, Avenue Président Pierre Angot 64 053 PAU CEDEX 9 FRANCE Tel : (33) 557.571.260 Fax : (33) 556.960.975 site du labo http://lcbie.univ-pau.fr site de l'équipe d'accueil http://lcbie.univ-pau.fr/Gcabi
