黄土的结构研究是黄土研究中的一个重要组成部分,它和黄土的物理力学性质、化学性质、成岩过程等有着密切关系。因此研究黄土的结构,无论在岩石学方面或是在工程地质、水文地质以及农业方面都具有十分重要的意义。黄土结构的研究方法,有宏观的肉眼观察和微观的显微镜观察。在显微镜下最基本、最常规的方法是镜下薄片观察。但由于黄土疏松、结构复杂、颗粒细小、孔隙裂隙多,因而用 The study on the structure of loess is an important part of loess research. It is closely related to the physical and mechanical properties, chemical properties and diagenesis of loess. Therefore, studying the structure of loess is of great significance both in petrology and in engineering geology, hydrogeology and agriculture. Loess structure research methods, macroscopic macroscopic observation and microscopic observation. The most basic and most common method under a microscope is microscopic observation. However, loess loosening, complex structure, small particles, pore fissures and more, so use
