本文介绍了扫描电子显微镜下研究锆石表面特征的方法。对黄土高原全新世黄土—古土壤系列中锆石表面特征进行观察,将表面特征按外观形态划分为六个种类,并对各类特征发生频数进行定量统计分析。认为锆石有丰富的表面特征反映沉积前后的风化作用性质和程度;进而讨论了黄土高原褐土和黑垆土盖层的成因。
This article describes a scanning electron microscope study of zircon surface characteristics of the method. The surface features of zircon in the Holocene loess-paleosol series on the Loess Plateau were observed, and the surface features were divided into six species according to the appearance morphology. Quantitative and statistical analysis was made on the frequency of occurrence of various characteristics. It is considered that zircons have abundant surface features that reflect the nature and extent of weathering before and after deposition. The causes of the caprock formation in the cinnamon and black sand are discussed.
