  skos:definition "Greenstone is a common generic term for valuable, green-hued minerals and metamorphosed igneous rocks and stones which early cultures used in the fashioning of hardstone carvings such as jewelry, statuettes, ritual tools, and various other artifacts. Greenstone artifacts may be made of greenschist, chlorastrolite, serpentine, omphacite, chrysoprase, olivine, nephrite, chloromelanite among other green-hued minerals. The term also includes jade and jadeite, although these are perhaps more frequently identified by these latter terms. The greenish hue of these rocks generally derives from the presence of minerals such as chlorite, hornblende, or epidote. (Adapted from: <a href=\"https://en.wikipedia.org/wiki/Greenstone_(archaeology)\">https://en.wikipedia.org/wiki/Greenstone_(archaeology)</a>)"@en, "\"Roche verte\" est un terme générique pour désigner des roches ignées métamorphiques de couleurs vertes, en particulier les schistes verts, le jade, les serpentinites... La teinte verte de ces roches provient très généralement de la présence de minéraux tels les chlorites, la hornblende verte, l'épidote, les serpentines, la jadéite, la trémolite (néphrite), l'omphacite, l'olivine, le chrysoprase, etc. (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Roche_verte\">https://fr.wikipedia.org/wiki/Roche_verte</a>)"@fr ;
