Cafetite is a rare titanium oxide mineral with formula (Ca,Mg)(Fe,Al)2Ti4O12·4(H2O). It is named for its composition, Ca-Fe-Ti. It was first described in 1959 for an occurrence in the , Afrikanda, Kola Peninsula, Murmanskaja Oblast, Northern Region, Russia. It is also reported from the Khibiny and massifs of the Kola Peninsula and from Meagher County, Montana, US. It occurs in pegmatites in a pyroxenite intrusion as crystals in miarolitic cavities. It occurs associated with ilmenite, titaniferous magnetite, titanite, anatase, perovskite, baddeleyite, phlogopite, clinochlore and kassite.

  • La cafetita és un mineral de la classe dels òxids. (ca)
  • Cafetit ist ein sehr selten vorkommendes Mineral aus der Mineralklasse der „Oxide und Hydroxide“ mit der idealisierten chemischen Zusammensetzung CaTi2O5·H2O und ist damit chemisch gesehen ein wasserhaltiges Calcium-Titan-Oxid. Cafetit kristallisiert im monoklinen Kristallsystem und entwickelt meist nadelige bis säulige Kristalle mit gestreiften Prismenflächen. Daneben findet er sich auch in Form faseriger, verworrener Mineral-Aggregate und Massen. Die durchsichtigen bis durchscheinenden Kristalle sind meist hellgelb bis farblos, können aber auch eine orangebraune Farbe annehmen. (de)
