High resolution imaging by TEM has revealed a mechanism for the weathering of intermediate microcline in a humid, temperate climate. Dissolution of the feldspar begins at the boundary of twinned and untwinned domains and produces circular holes which enlarge to form negative crystals. Amorphous, ring-shaped structures develop, about 25 Angstrom in diameter, within the larger holes. These rings, in turn, crystallize to an arcuate phase and then to crinkled sheets of illite or dehydrated montmorillonite. -from Authors
