近若干年来,在构造地质研究的实践过程中,在鉴定结构面力学性质的工作中,日益感到研究微观构造是对结构面鉴定的重要性。在野外作构造地质调查时,只凭肉眼对岩石进行观察分析,常常不能满足鉴定工作的需要,甚至还容易作出不确切的判断。一般的岩矿鉴定工作,应侧重物质成份的分类鉴定,在结构上,往往只作一般的描述,因而满足不了要求。 In recent years, in the practice of structural geology research, in the work of identifying the mechanical properties of structural planes, it is increasingly felt that the study of microstructure is of importance to the identification of structural planes. In the field of structural geology survey, only by naked eye observation and analysis of the rock, often can not meet the needs of identification work, and even easy to make inaccurate judgments. General identification of rock and mineral, should focus on the classification of material identification, in the structure, often only for general description, which can not meet the requirements.
