Abstract

This paper addresses for the first time the internal structure of lens 2 of the Shulepovo refractory clay deposit. The SEM study of representative samples from the entire lens section revealed relationships between the major minerals: kaolinite, halloysite, illite, and quartz. The lens was previously considered homogeneous, but its detailed study revealed a clear internal zonality. The structural forms of kaolinite (hexagons, vermicules, and films), halloysite (acicular or columnar and stellate crystals), and illite (intergrowths and bands) are distinguished. Their variable relationships define the vertical zonality of the lens.

Shulepovo矿床（俄罗斯中欧梁赞地区）陶土中高岭石的矿物组成和形态特征

摘要

本文首次探讨了Shulepovo耐火粘土沉积物的晶状体2的内部结构。整个镜片截面中代表性样品的SEM研究揭示了主要矿物之间的关系：高岭石，埃洛石，伊利石和石英。晶状体以前被认为是均匀的，但对其详细的研究显示出明显的内部带状性。高岭石（六边形，ver石和薄膜），埃洛石（针状或柱状和星状晶体）和伊利石（共生体和带状）的结构形式有所区别。它们的可变关系定义了晶状体的垂直区域。
