Liuskikivi, also known as foliated rock, is a type of metamorphic rock characterized by its distinct layering or banding, which is caused by the alignment of minerals during the metamorphic process. This alignment occurs due to the directional pressure exerted on the rock during metamorphism, which can be the result of tectonic forces or the intrusion of magma.

The banding in liuskikivi can vary in thickness and color, depending on the minerals present and their degree of metamorphism. Common minerals found in liuskikivi include quartz, feldspar, mica, and hornblende. The presence of mica, in particular, often gives liuskikivi a shiny or glossy appearance.

Liuskikivi is commonly found in regions that have undergone significant tectonic activity, such as mountain ranges and orogenic belts. Examples of liuskikivi include gneiss, schist, and phyllite. These rocks are often used in construction, as decorative stone, and in various industrial applications due to their durability and aesthetic appeal.

The study of liuskikivi provides valuable insights into the geological history of a region, as the banding and mineral composition can reveal information about the temperature, pressure, and fluid conditions present during metamorphism. Additionally, the alignment of minerals in liuskikivi can be used to infer the direction and magnitude of tectonic forces that acted on the rock.
