Abstract

Abstract

Etch figures of different crystallographic faces on quartz, garnet, olivine, zircon and andalusite have been observed and analyzed. The relationship between etch figures and crystal face symmetry as well as the characteristics of face structures is summarized. It is shown that etch figures can not only reflect the face symmetry, but also reflect the face crystallographic significance. The crystal faces with different crystallographic significance on the same crystal must have different etch figures, even though they may have the same symmetry. However, the faces with the same symmetry among different crystals maybe have the same etch figures. Etch figures are mainly related to the face symmetry, similar to the crystal morphology, but not related to the detailed arrangement of the atoms or ions on the faces. The etch figures formed by different solvents on the same face may be completely different. Some etch figures can be explained by the intersection edges between the growth faces on the crystal habit and the etching face. This research clarifies the mechanism of resolved shapes on crystals, illustrates the relationship between the resolved morphology and growth morphology and indicates the acid or alkali environment of the crystals.
