| Description | Alkali contents (potassium and sodium) were determined in the carbonate rocks of Líšeň Fm. (limestones and calciturbidites) in the dump area in the eastern part of the Mokrá Quarry (Moravian Karst). The alkali contents are relatively high: the siliciclastic beds in calciturbidites contain 1.8–5.0 wt. % K2O and 0–2.2 wt. % Na2O. The enhanced potassium contents in calciturbidites are associated with feldspar and mica clasts in siliciclastic beds. The sodium contents in siliciclastic beds come from albite (clastic and authigenic). The carbonate beds of the calciturbidites show only very low concentrations of both elements. |
