地质学科发展史表明,认识岩石和矿物的技术方法的变革,极大地影响着地质学科发展的速度和水平.十九世纪二十年代,光学显微镜在地质学领域中的应用,使人们对地质由宏观物理性质、几何形状和总体化学成分的观察,发展到矿物的光学性质、地质体的显微矿物成分、地质体的显微结构和构造及其与地质体宏观现象之间的相关关系的认识,为岩石学、矿相学和光性矿物学提供了
The history of the development of geology shows that the change of technical methods of understanding rocks and minerals has a great influence on the speed and level of the development of geology.In the 1920s, the application of optical microscope in the field of geology, The observation of macroscopic physical properties, geometry and overall chemical composition, the development of the optical properties of minerals, the microscopic mineral composition of geologic bodies, the microstructure and structure of geologic bodies and their relationship with the macroscopic phenomenon of geological bodies , Provided for petrology, mineralogy and phototrophology
