矿物晶体表面微形貌(surface Microtopography)研究是近一、二十年来迅速发展起来的矿物学新领域,它以发育良好的天然矿物和人工晶体为对象,应用灵敏的位相差显微镜和多光束干涉仪等光学显微技术,揭露晶体表面上各种精细的生长或溶解图案(包括不同形态的螺蜷线、生长层、生长条纹、微斜面、蚀坑结构等),精确测量每一生长台阶(或生长层)的高度及台阶间宽度,运用近代晶体生长理论解释所研究的微形貌特征与矿物生长条件,生长过程的内在连系,达到从微观角度解决矿物个体生长发育历史的目的。
Surface Microtopography is a new mineralogical field which has been developed rapidly in the past one or two decades. It uses well-developed natural minerals and artificial crystals as object, and uses the sensitive phase-contrast microscope and multi-beam interference Optical microscopy, revealing various fine growth or dissolution patterns (including different forms of spiral curls, growth layers, growth stripes, micro-bevels, pit structures, etc.) on the surface of the crystal, accurately measuring the height of each growth step Or growth layer) and the width of the terrace. By using modern crystal growth theory to explain the intrinsic relationship between the micro-topographical features and mineral growth conditions and growth process, the purpose of solving the individual growth and development history of minerals from the microscopic point of view is achieved.
