โœฆ Synopsis

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] direction is depending on the concentration of the etchant and on the inclination of the dislocation line in the plane (110).

Depth points do not lie on any diagonals. Eccentricity of asymmetrical etch pits along the [110] direction is depending on the concentration of the etchant and on the inclination of the dislocation line in the plane (110).

## Abstract Thermal etch pits are observed on calcite cleavages when the latter are kept at 520ยฐC to 560ยฐC in atmosphere for some hours. Boundaries of the above etch pits are circular, hexagonal and rhombic and they are dependent upon the temperature of etching. Different etch pit morphology is obs
