Biotites and chlorites as interlayered biotite-chlorite crystal

Bulletin de Minéralogie, 1985
En microscopie électronique à transmission et de haute résolution, il est fréquemment observé dans les biotites et les chlorites qu'il y a en fait mélange de feuillets élémentaires de biotite et de chlorite. D'après la terminologie courante, ces cristaux sont des interstratifications biotite-chlorite.

Sorption of biotite

Forschungszentrum Karlsruhe. Wissenschaftliche Berichte, 2009
Gneissic rock types are common in the coastal regions of the Baltic Sea and in the area of the planned deep repository at Olkiluoto. Based on experimental data and molecular modelling of mineral surfaces, the chemical reactions governing the sorption of Ni(II) and Eu(III) were interpreted using well-established thermodynamic sorption models.
