Horizon (geology)

A geological horizon is an often extensive, extending as low powerful layer of rock body, which is of particular geoscientific or on mining interests - for example, a seam, a water-bearing or separating sediment or rock layer, a shear zone or a paleontological treasure horizon. A horizon within a rock package, which can be identified easily by appearance, composition, fossil content or other characteristics is called a marker horizon. Marker horizons are important clues to the geological mapping of an area.

In soil science, soil horizons are common areas within the soil, which differ by similar characteristics and properties of the super-and subjacent areas.
