Abstract

The surface microtopography of rough basal faces and internal inhomogeneities of amethyst crystals from Four Peaks, Arizona, were investigated by optical, SEM and CL tomography. Rough interface overgrowth was shown to have taken place along the c axis on mechanically broken surfaces, and the present rough basal surfaces were demonstrated to have formed because of later heavy dissolution.
