A Dictionary of Earth Sciences | 1999 | | Copyright

oxic horizon Mineral subsoil soil horizon that is at least 30 cm thick and is identified by the almost complete absence of weatherable primary minerals, by the presence of kaolinite clay, insoluble minerals such as quartz, hydrated oxides of iron and aluminium, and small amounts of exchangeable bases, and by low cation-exchange capacity. It is the distinguishing subsoil horizon (B horizon) of an Oxisol.
