laskimokanavien

Laskimokanavien is a Finnish term that translates to "calculator channels" or "calculating channels." It refers to a specific type of geological formation found in certain limestone and dolomite rock environments. These formations are characterized by a network of narrow, often winding channels or fissures that have been enlarged by the dissolution of the rock, primarily by water containing dissolved carbon dioxide.

The process of forming laskimokanavien is a form of karstification, similar to the development of caves and sinkholes. Over long periods, slightly acidic rainwater percolates through the rock, slowly dissolving the calcium carbonate. This dissolution is more pronounced along existing fractures and bedding planes, leading to the widening and deepening of these features into channels. The term "laskimokanavien" specifically describes these often sinuous and interconnected passages, which can vary in size from a few millimeters to several meters in width.

These formations are significant in hydrogeology as they can act as conduits for groundwater flow. Water entering the surface through rainfall can quickly travel through these channels, making the underlying rock susceptible to rapid contamination if pollutants are introduced. The presence of laskimokanavien can also influence the stability of the ground, particularly in areas where these channels are extensive or intersect with human infrastructure. Understanding their distribution and characteristics is important for land-use planning, water resource management, and geological surveys.
