Distribución de Mg en conchas de Crassostrea gigas : control microestructural y correlaciones cristaloquímicas
The realization of geochemical studies on the right valve of Crassostrea gigas's shells has allowed demonstrating a microestructural control on the concentration of Mg. The transects studied in this work show that the ratio Mg/Ca is higher in the Prismatic (SP) and Chalk microstructures than in...
