Andosol

Andosols (from Japanese an meaning dark and do soil, a synonym of kuroboku) are soils found in volcanic areas formed in volcanic tephra. In some cases can Andosols also be found outside active volcanic areas. Andosols cover an estimated 1–2% of earth's ice-free land surface. Andosols are a Reference Soil Group of the World Reference Base for Soil Resources (WRB). They are closely related to other types of soils such as Vitrosols, Vitrandosols, Vitrons and Pumice Soils that are used in different soil classification systems.
