Norway is the main source of olivine in Europe, particularly in an area stretching from [[Åheim]] to [[Tafjord]], and from [[Hornindal Municipality|Hornindal]] to Flemsøy in the [[Sunnmøre]] district. There is also olivine in [[Stad Municipality]]. About 50% of the world's olivine for industrial use is produced in Norway. At Svarthammaren in [[Norddal Municipality]] (now [[Fjord Municipality]]), olivine was mined from around 1920 to 1979, with a daily output up to {{convert|600|MT|lk=on}}. Olivine was also obtained from the construction site of the hydro power stations in Tafjord. At Robbervika in Norddal municipality an open-pit mine has been in operation since 1984. The characteristic red color is reflected in several local names with "red" such as ''Raudbergvik'' (Red rock bay) or ''Raudnakken'' (Red ridge).<ref>Furseth, Astor (1987): ''Norddal i 150 år''.

[[Hans Strøm]] in 1766 described the olivine's typical red color on the surface and the blue color within. Strøm wrote that in Norddal district large quantities of olivine were broken from the bedrock and used as [[sharpening stone]]s.<ref>Strøm, Hans: ''Physisk og Oeconomisk Beskrivelse over Fogderiet Søndmør beliggende i Bergen Stift i Norge.''
