kellalähteet

Kellalähteet are a natural geological phenomenon found in various parts of the world, particularly in Arctic and sub-Arctic regions. The term "kellä" is a Finnish word that roughly translates to " spring" or "fountain". These unique features are characterized by their white or light-colored coloration, resulting from the accumulation of calcite or other minerals.

Kellalähteet are essentially cold-water springs that emit geothermal water, typically between 4-16°C in temperature. The geothermal activity is thought to be the result of volcanic forces deep within the Earth's crust, heating the surrounding rocks and ground water. As the water rises to the surface, it brings with it dissolved minerals, which eventually precipitate out, creating the characteristic white or light-colored appearance of kellalähteet.

Kellalähteet are often found near old volcanic fields,ovolcanoes, or within other areas of geologic activity. In some regions, such as Finland, Iceland, and Alaska, kellalähteet have become popular tourist attractions, allowing visitors to experience the natural beauty of these unique geological features.

Scientific studies of kellalähteet have helped researchers understand more about the Earth's interior and the processes that shape our planet's surface. By analyzing the mineral composition and temperature of kellalähteet, scientists can gain insights into the Earth's thermal and chemical evolution.
