| dbo:abstract | La clinohumita és un mineral de la classe dels silicats, que pertany al . Va rebre el seu nom al segle xix per Alfred Des Cloizeaux en al·lusió a la seva estructura cristal·lina monoclínica i per la seva relació amb la humita. (ca) Clinohumite is an uncommon member of the humite group, a magnesium silicate according to the chemical formula (Mg, Fe)9(SiO4)4(F,OH)2. The formula can be thought of as four olivine (Mg2SiO4), plus one brucite (Mg(OH)2). Indeed, the mineral is essentially a hydrated olivine and occurs in altered ultramafic rocks and carbonatites. Most commonly found as tiny indistinct grains, large euhedral clinohumite crystals are sought by collectors and occasionally fashioned into bright, yellow-orange gemstones. Only two sources of gem-quality material are known: the Pamir Mountains of Tajikistan, and the Taymyr region of northern Siberia. It is one of two humite group minerals that have been cut into gems, the other being the much more common chondrodite.

Recibió su nombre en el siglo XIX por Alfred Des Cloizeaux en alusión a su estructura cristalina monoclínica y por su relación con la humita. (es) La clinohumite est un minéral du groupe de la humite, un silicate de magnésium de formule (Mg,Fe)9(SiO4)4(F,OH)2. Il a été découvert en 1876 sous forme non gemmifère au Vésuve par Alfred Des Cloizeaux. Des dépôts exploitables ont été mis au jour en 1983 au Pamir, puis en 2000 dans le district dolgano-nénètse du Taïmyr, en Sibérie et en 2005 dans les monts Mahenge en Tanzanie.
