Karstajos

Karstajos is a term that refers to a specific geological formation found in karst landscapes. Karst topography is characterized by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum, over long periods. This dissolution creates distinctive underground drainage systems with sinkholes, caves, and underground streams. Karstajos specifically describes features within these environments that are indicative of active or recent karst processes. These can include newly formed sinkholes, collapsing cave roofs, or areas where surface water is rapidly disappearing underground. The term emphasizes the dynamic and evolving nature of karst regions.

The formation of karstajos is driven by the chemical weathering of bedrock. Rainwater, slightly acidic due to dissolved carbon dioxide, seeps into the ground and reacts with the soluble rock. Over time, this process enlarges existing fractures and bedding planes, leading to the formation of conduits and eventually larger underground cavities. When the roof of an underground cavity becomes too thin or unstable, it can collapse, forming a sinkhole. Areas exhibiting such features are often considered karstajos, highlighting the ongoing geological activity. Understanding karstajos is important for land management, as these areas can be prone to subsidence and can affect water quality due to the direct connection between surface and groundwater.
