szénkétes

Szénkétes is a Hungarian geological term referring to carbonate rocks, which are sedimentary rocks primarily composed of carbonate minerals such as calcite (CaCO₃) and dolomite (CaMg(CO₃)₂). These rocks form through chemical or biological processes in marine environments, often resulting in distinct layering and crystalline textures. Common types include limestone (dominantly calcite) and dolostone (rich in dolomite). Carbonate rocks are notable for their solubility in acidic conditions, contributing to features like karst topography (caves, sinkholes). They also serve as significant reservoirs for oil, gas, and groundwater, and are widely used in construction as building stone. Szénkétes rocks are prevalent in various regions globally, including the Carpathian Basin in Hungary and extensive formations in the United States and Europe.
