12th exchange exchange for microminerals and arenophilia

The Val D'Yerres Sénart Geological Club (CGVYS) and Micromonteurs organize their 12th exchange of microminerals and arenophilia (sand) exchanges in Quincy-Sous-Sénart (91), from 9:00 to 18:00. Hoping that you will come many at this eleventh meeting between Micromonteurs and the CGVYS because it promises to be European with the arrival of our Belgian friends. Places are limited, so don't delay in returning your registration form to us by February 29, 2020.
