综合分析了石英、石榴子石、橄榄石、锆石、红柱石的各不同结晶学意义的晶面腐蚀像特点,总结了晶面腐蚀像与晶面对称性及晶面结构特点之间的关系.腐蚀像不仅可以揭示晶面及晶体的对称性,还可以揭示晶面的结晶学意义,即同一晶体上的不同结晶学意义的晶面,尽管对称性相同,也具有不同的腐蚀像;不同晶体之间的具有相同对称性的晶面可能会有相同的腐蚀像;腐蚀像类似于一种宏观晶体形态,主要与晶面的对称性有关,与晶面上原子、离子排列的结构细节关系不大;同一晶体的同一晶面在不同的腐蚀剂中所得的腐蚀像也可能完全不同;有些晶面的腐蚀像可以用晶体生长形态的常见晶面与被腐蚀面的交棱来解释.该研究在揭示晶体溶解形态机理、将溶解形态与晶体生长形态对比、用溶解形态来反映晶体曾经经历的酸-碱环境等方面具有理论与实际意义.
In this paper, the characteristics of the different crystallographic aspects of quartz, garnet, olivine, zircon and andalusite are analyzed. The relationship between the corrosion image of the quartz surface, the symmetry of the crystal plane and the structural characteristics of the crystal plane The relationship between corrosion images not only reveals the symmetry of crystal planes and crystals, but also reveals the crystallographic meaning of crystal planes, that is, crystal planes with different crystallographic significance on the same crystal have different corrosion images despite the same symmetry. The planes of the same symmetry between different crystals may have the same corroded image; the corroborations resemble a macroscopic crystal morphology that is mainly related to the symmetry of the crystal plane and the structural details of the arrangement of atoms and ions on the crystal plane The same crystal surface of the same crystal in different etchant corrosion images may also be completely different; some of the crystal surface can be like the crystal growth morphology of the common crystal surface and the corroded surface of the intersection angle to explain. The study has theoretical and practical significance in revealing the mechanism of crystal dissolution, comparing the dissolution morphology with the crystal growth morphology, and using the dissolution morphology to reflect the acid-base environment that the crystal has undergone.
