streszczenie
Multiple mica-like monocrystals, 3 mm in size, are formed when smectite is saturated with 1N Pb(CH3COO)2 solution. The appearance of neoformations meta-stable to water may be attributed to inner-sphere complex of Pb2+ cations and smectite macroanion with its charge being centered in the tetrahedral layer of beidellite structure. Textured aggregates and few neo-formation monocrystals are found in Pb(CH3COO)2-saturated kaolinite specimens. No changes of particle organization in clay minerals saturated with 1N ZnCl2 solution are registered.
