mineraliserer

Mineraliserer is the Norwegian term for the verb mineralisere, meaning to convert into minerals or to cause the formation and deposition of minerals. In practical use it describes processes by which minerals are added to or formed within a substance or environment. The concept spans natural geological and biological contexts as well as industrial and environmental applications, and it is used to describe both the onset of mineral formation and the growth of mineral-rich zones.

Geological mineralisering refers to the formation and accumulation of mineral deposits in rocks, typically through hydrothermal circulation, metasomatism or metamorphism. Fluids transport dissolved metals and ligands, and minerals precipitate as veins, disseminations or replacement bodies. Ore bodies such as gold, silver, lead, zinc and copper are common products of these mineraliserings processes, often revealing characteristic textures and parageneses that help interpret the history of a rock or district.

Biomineralisation, a related concept in biology, describes how organisms actively deposit minerals to build hard tissues and structures. Examples include bones and teeth in vertebrates, shells in mollusks, and spicules in some invertebrates. Organic matrices and proteins regulate mineral growth, leading to materials such as hydroxyapatite in bone and enamel, or calcium carbonate in shells.

Pathological mineralisation can occur in humans and animals when minerals deposit in soft tissues, producing calcifications in places such as arteries, kidneys or joints. In dentistry, enamel and dentin undergo controlled mineralisation, forming highly mineralised tissues that protect teeth.

Industrial and environmental contexts include mineralisation during sediment cementation, stabilization of waste through mineral formation, and microbial mineralisation of organic pollutants, which slowly convert organic material into inorganic mineral forms.
