Dolomena

Dolomena refers to a large, shallow depression or sinkhole, often bowl-shaped or funnel-shaped, formed by the collapse of the roof of a cave or cavern in karst terrain. Dolomenas are typically larger than sinkholes or dolines, ranging from tens to hundreds of meters in diameter and depth. The term is often used in geological and geomorphological contexts when discussing karst landforms. They are significant features of karst landscapes and can impact groundwater flow and surface drainage. Their formation can be a slow, gradual process of erosion or a more sudden and dramatic collapse. Dolomenas may contain accumulated sediment and organic matter, potentially forming temporary or permanent ponds or lakes.
