Luonnonkiveä

Luonnonkiva is a type of Finnish limestone that is formed from the remains of ancient sea creatures such as coral, algae, and shellfish. This type of limestone is commonly found in areas where ancient seas once existed, such as in the southwestern part of Finland.

The formation of Luonnonkiva limestone began approximately 440 million years ago, during the Silurian period, when Finland was still underwater. Over time, the organic matter from these ancient sea creatures accumulated and compressed, eventually transforming into a solid mass of limestone.

The name Luonnonkiva is derived from the Finnish words "luonnon" meaning "natural" and "kiva" meaning "stone". This type of limestone is prized for its unique texture and structure, which features a combination of fine-grained minerals and fossilized remains of ancient sea creatures.

Luonnonkiva limestone is composed primarily of the minerals calcite and aragonite, which provide its distinctive texture and structure. In addition to its aesthetic value, Luonnonkiva limestone is also valued for its durability and resistance to weathering. It is often used in construction and decorative stone applications, such as in the creation of buildings, bridges, and monuments.

Due to its relative rarity and limited geographical distribution, Luonnonkiva limestone is considered a valuable and sought-after material in the stone industry. Its unique characteristics and potential applications make it an interesting subject of study for geologists and naturalists interested in the natural history and properties of limestone.
