光性矿物检索鉴定程序设计原理与应用

The Program Principle and Application of Microscopic Identification of Minerals

计算机技术常应用到镜下鉴定光性矿物工作中,本文以Visual Basic为工具开发出用于镜下鉴定矿物的辅助分析程序,介绍了光性矿物鉴定程序的设计原理和使用方法,包括矿物属性分析及赋值、鉴定误差减小方法及其应用。在光性矿物镜下鉴定时输入所观察矿物全部或部分光学性质,通过程序计算与比较,显示出最可能的查询矿物。矿物检索以贵橄榄石为例,在输入正确光性矿物属性的前提下,可准确地得出鉴定结果,有效地提高了镜下矿物鉴定的效率和准确度;查询结果中配有详细图片和属性描述,可以进一步查询矿物的详细光学性质、成因产状及其他鉴定特征;此外鉴定分析程序也可以用于建立矿物信息数据库。

The microscopic identification of minerals can often be improved with the use of computer technology.An auxiliary analysis program for the microscopic identification of minerals based on Visual Basic tools is described in this paper.Design methods and procedures of the program,including mineral properties analysis and digitization,identification error reduction methods are discussed.When using the application for determination of minerals,it is acceptable to input complete or part of the optical properties of query minerals during microscopic observation.Through calculation and comparison,final search results can match most query minerals.The application analysis results demonstrate the accuracy and efficiency for identifying query minerals.The program can also identify more mineral information,such as optical properties,the causes of the occurrence and identification characteristics.In addition,the program can be used to establish a mineral information database.
