kalkifierade

Kalkifierade is a Swedish term meaning calcified or hardened by the deposition of calcium-containing minerals, typically calcium carbonate or calcium phosphate. The word is used across several scientific fields to describe material that has been strengthened or preserved through mineralization.

In biology and medicine, kalkifiering refers to calcification, the process by which calcium salts accumulate in soft tissues or developing hard tissues. It can be physiological, as in bone formation, dentin and enamel mineralization, or pathological, as in dystrophic calcification in damaged tissues or metastatic calcification associated with metabolic disturbances. Calcification also occurs in soft tissues such as blood vessels and heart valves in certain disease states.

In geology and paleontology, kalkifierade describes fossils or geological structures that have been preserved or formed through calcium carbonate deposition. This includes fossil shells and skeletons of marine organisms, as well as permineralized remains in which original material is replaced or encased by calcite. Limestone, composed largely of calcium carbonate, is a common broader context in which calcified remains are studied.

Common examples include calcified teeth and bones in living organisms, calcified vascular or soft-tissue lesions in pathology, and fossilized or mineralized organisms and structures in the fossil record. The term emphasizes the role of calcium minerals in hardening, preserving, or forming the studied material.
