RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 20, ES2007, doi:10.2205/2020ES000706, 2020 Figure 8. SEM photomicrographs: A, B) – microcrystalline overgrowth quartz on the surfaces of quartz grains and in the pore spaces; C) – pseudo-hexagonal kaolinite crystals in the form of pore-fillings material; D) – subhedral to euhedral blocky crystals and clusters of kaolinite booklets; E) – cabbage head-like morph of chlorite developed on the surfaces of quartz grains; F) – chlorite plates randomly orientated on grains surfaces enclosing the authigenic quartz and filling, and lining the pores; G) – Illite in the form of grain-coatings and pore-fillings; H) – Illite-smectite mixed layers as grain-coatings and pore-fillings.
