Kerrostuneina

Kerrostuneina is a Finnish term used to describe something that is arranged or formed in layers or strata. It functions as an adjective or adverb and is derived from kerrostua, meaning to become layered, and kerros, meaning layer. The form is commonly used across scientific and descriptive contexts to indicate a visible or measurable layering within a material, sediment, or structure.

In geology and sedimentology, kerrostuneina describes rocks and sediments that show distinct horizontal or planar layering resulting from successive deposition or growth processes. In soil science, it can refer to soil profiles where horizons are clearly differentiated, reflecting layered formation over time. The concept is also applicable in other fields where laminated or stratified structures are relevant, such as the study of laminated metals, ice cores, or laminated wood, where the term emphasizes the presence of multiple, separable layers.

Usage notes: kerrostuneina emphasizes the organized layering rather than a single uniform mass. It is typically used with nouns describing the material or structure (for example, rocks, sediments, soils) and can appear in descriptive or analytical writing. The term relates to kerrostuma (layering or stratification) and kerrostuneisuus (the property of being stratified).
