About Pyrochlore GroupHide

Formula:

A₂Nb₂(O,OH)₆Z

A is Na, Ca, Sn²⁺, Sr, Pb²⁺, Sb³⁺, Y, U⁴⁺, H₂O or ◻.

Z is OH, F, O, H₂O or ◻

Lustre:

Vitreous, Resinous

Member of:

Pyrochlore Supergroup

Name:

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.

First Recorded Locality:

ⓘ Stavern (Fredriksvärn), Larvik, Vestfold, Norway

Nb-dominant members of the Pyrochlore Supergroup.

The nomenclature was recently revised by Atencio et al. (2010) and Christy and Atencio (2013).
A correct identification of the individual members of the pyrochlore group is only possible using a combination of several analytical methods.

Varieties of Pyrochlore GroupHide

Aluminobetafite (of Kawai)
Calciobetafite (of Mazzi & Munno)	A dicredited mineral, earlier defined as a betafite. According to the new nomenclature of the Pyrochlore Supergroup (Atencio et al. 2010) "betafite" is defined as a calcium-rich and Ti-dominant pyrochlore. The type calciobetafite is Nb-dominant, not Ti-d...
Ceriopyrochlore (of Hogarth 1977)
Plumbopyrochlore (of Skorobogatova et al.)
Samiresite	A Pb-bearing variety of Uranpyrochlore. Originally reported from Samiresy, Sahatany Pegmatite Field (Mt Bity (Ibity) area), Vakinankaratra Region (Betafo - Antsirabé region), Antananarivo Province, Madagascar.
Stibiopyrochlore (of Pezzotta et al.)
Uranpyrochlore (of Hogarth 1977)	Uranpyrochlore was previously considered to be the uranium-dominant member of the Pyrochlore group (Hogarth, 1977) but was discredited by Atencio et al. (2010) due to lack of acceptable analyses. The samples named as uranpyrochlore in previous literature...
Yttropyrochlore (of Hogarth 1977)
Zero valent dominant member of Pyrochlore Group	A pyrochlore group member where there is a cation deficit comprised mainly of H₂O or site vacancies. This name is used to describe any pyrochlore where it is not possible to specify more accurately than this.
