Surfaces of low-albite crystals, a member of the natural feldspar group, were studied by scanning force microscopy immediately after cleavage. Data presented exhibit typical steps corresponding to the atomic structure of albite. When the albite surface is exposed to ambient air we observed a time-dependent change in surface morphology emanating from the step edges. To explain such phenomena we propose an atomic model.
