(1997): The Sirgala Member consists of alternating multicoloured clays and siltstones with interlayers and lenses of light-coloured sandstones, the share of which increases upward the section. Most of detrital grains are subrounded quartz with a small quantity of feldspars (up to 10%) and micas (mainly muscovite). In the clay fraction, kaolinite slightly prevails over illite. Chlorite is uncommon. The mineral composition suggests that these deposits derived from the weathered zone of sedimentary rocks. ViitedMeidla, T. 2017.
