中文摘要：

矿物晶体腐蚀像是一种研究晶体对称、晶格缺陷等传统的方法。对腐蚀像提出了一个全新的研究思路，建立各种不同矿物晶体的腐蚀像立体模型，从而可以在这个模型上进行：①腐蚀像的晶体对称理论意义及其在岩石中矿物晶体定向作用的研究；②腐蚀像所反映的晶格缺陷与定向及其地质意义的研究；③腐蚀像所反映的晶体溶解机理的结晶学各向异性特征的研究。这些研究充分挖掘了腐蚀像在地质学、矿物学中的新的研究意义。

英文摘要：

Crystal etching, a traditional method to study the crystal symmetry and crystal defects, should be a new application in modern mineralogy. This paper proposes a new idea to establish the three dimensional model of etching figure of mineral crystals. Based on the three dimensional model of etching figure, this method can be used to study： （1） crystal symmetry theoretic signification of the etching figure and the crystallographic orientation of minerals in rocks; （2） crystal defects and their crystallographic orientations for indicating the geological environments; and （3） anisotropy characteristics of the crystal dissolution mechanism. These studies have furthered the application of etching figures in modern mineralogy and geology.
