Abstract/Notes | SummaryRhombohedral cleavage faces of quartz have been etched hydrothermally and with fused KOH. Stratigraphical etch patterns were observed on isolated cleavages, matched cleavage faces, and opposite sides of a thin flake. The angle between the () cleavage plane and the planes responsible for the stratigraphical patterns was almost equal to the interfacial angle, 46° 16′ between adjacent rhombohedral faces. It is concluded that the stratigraphical patterns formed by preferential etching reveal the edges of weak planes deposited during growth. The implications are discussed. |
