## Abstract Very low concentration of mineral acids and monocarboxylic acid (less then 0.001%) produces triangular etch pits on calcite cleavages at dislocations intersecting the surface. The orienation of triangular etch pits is opposite with respect to percussion mark on calcite cleavages. This m
## Abstract There are two types of chemical eccentric etch pits. Deepest points are always lying on the shorter diagonal. โ Symmetrical etch pits the deepest points of which lying on the diagonals show dislocation lines in the plane (110). Eccentricity of symmetrical etch pits along the [110] dire
