Sorakivi

Sorakivi is a Finnish term used to describe a type of stone or rock formation found in certain geological contexts. The word itself can be translated as "gravel stone" or "aggregate stone," suggesting a composition of smaller rock fragments cemented together. These formations are often the result of geological processes where loose materials, such as sand, gravel, and pebbles, are compacted and lithified over long periods.

In Finland, sorakivi can be found in areas with significant glacial deposits or alluvial fans, where the movement of water and ice has brought together and sorted various rock materials. The specific characteristics of sorakivi, such as its grain size, composition, and strength, can vary depending on the source of the materials and the conditions under which it formed. This variability makes sorakivi a diverse geological feature.

Geologically, sorakivi is often classified as a type of sedimentary rock, specifically a conglomerate or breccia, depending on the angularity of its constituent clasts. In construction and civil engineering, sorakivi, or materials derived from it, can be utilized as aggregate for concrete, road building, and landscaping due to its availability and structural properties. The term is primarily used in Finnish geological and engineering contexts.
