- •
R0 corrensite-chlorite, R1 chlorite-smectite, chlorite, prehnite and zeolites formed by hydrothermal alteration.
- •
Several superimposed mineral assemblages developed during the emplacement (≤ 300 °C) and cooling of the Kramarica Sill.
- •
Laumontite and R0 corrensite-chlorite formed in coarse-grained and/or fractured rocks during the cooling of the sill.
- •
The reacting hydrothermal fluids were possibly rich in the Mg2+ and Ca2+ ions and originated from the dolomite basement.
