Abstrakt:	The distinction of montmorillonite proper from beidellite is often based on the Li-text proposed by GREENE-KELLY (1953). However, when saturated with Li, true montmorillonite samples that contain considerable admixtures of SiO[sub2] or Fe[2]O[3]hH[sub2]O behave in the same way as beidellites. An irreversible sorption of Li (after annealing at 250°C) is observed in such samples only after the admixed amorphous substance has been removed by leaching with a NaCO[sub3] or HCI solution.
