Sisäkuorilta

Sisäkuorilta is a Finnish term that translates to "inner shells" or "inner layers." It is most commonly used in the context of geology and soil science to describe specific horizons within a soil profile. These inner shells are typically found beneath the topsoil (A horizon) and above the parent material (C horizon). They represent zones where various soil-forming processes have altered the original material over time.

Geologists might use sisäkuorilta to refer to distinct layers that have undergone processes like illuviation, where minerals and organic matter have leached down from upper horizons and accumulated. These layers can vary significantly in color, texture, and chemical composition depending on the parent material, climate, and vegetation. For instance, a common sisäkuorilta layer is the B horizon, often referred to as the subsoil. This zone can be richer in clay, iron oxides, or other materials that have been transported from above.

In some technical contexts, the term might also be applied to the internal structure of certain geological formations, referring to distinct concentric layers within rocks or mineral deposits. The specific meaning of sisäkuorilta is therefore highly dependent on the scientific discipline and the particular subject being discussed, though its core meaning relates to internal, distinct layers or shells.
