Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Pantellerite is a peralkaline rhyolite. It has a higher iron and lower aluminium composition than comendite

Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Pantellerite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
