"Pyrochlore" is no longer the name of an approved mineral species.
The pyrochlore group of the pyrochlore supergroup is a large group of minerals, mostly primary, forming in
pegmatites and in igneous rocks dominated by carbonate minerals. It is an accessory mineral in silica-poor rocks, often occurring with magnetite, apatite and zircon. It also accumulates in some detrital deposits.

Localities

At the Silver Crater mine, Hastings county, Ontario, Canada, pyrochlore occurs in a small carbonatite together with zircon crystals (R&M 94.5.414).
