Mineral Composition and Morphological Features of Kaolinite of Ceramic Claysof the Shulepovsky Deposit (Ryazan Region, Central Part of European Russia)
Data on the internal vertical zoning of refractory lenses of the Shulepovsky Deposit were obtained for the first time as a result of this study. The SEM research of samples across the entire lens section revealed the relationship between the main minerals that forming the lens: kaolinite, galluasite, illite and quartz. Previously, it was thought that the lens is homogeneous, but the results of the study show that there is a clear internal zoning The structural form of kaolinite (hexagons worm’s form and film), halloysite (needle-like or columnar, and stellate crystals), illite (joints and bands), the relationship of which forms the vertical zonality of the lens.
