Name origin: The pyrochlore group gets its name from the generic name pyrochlore which was first introduced by J. J. Berzelius for a cubic mineral found by N.O. Tank in the 1820s in a syenite pegmatite at Stavern (formerly Fredriksvärn), Norway (Wöhler 1826). It is derived from the Greek πΰρ, fire, and χλωρός, green in allusion to the fact that the mineral usually turns green on ignition.
