karstokivien
Karstokivien, in Finnish geology, refers to stones that have undergone karstification, typically associated with carbonate rocks such as limestone (CaCO3) and dolostone (CaMg(CO3)2). The term describes both the rock material and the surfaces or fragments produced by karst processes.
Karstification is driven by the dissolution of rock by mildly acidic water, usually groundwater that contains
Karstokivien occur wherever carbonate rocks are exposed to karstic processes, and they are of interest to geologists
Use and implications: In some regions, karst stones are quarried as building material or decorative rock, though
