About RenarditeHide

Alphonse François Renard
Formula:
Pb(UO2)4(PO4)2(OH)4•H2O
Colour:
Yellow
Lustre:
Greasy
Specific Gravity:
4.0
Crystal System:
Orthorhombic
Name:
Named in honor of Alphonse François Renard (28 September 1842, Ronse, Belgium - 9 July 1903, Elsene Belgium), geologist and petrographer at the University of Ghent, Belgium. Among other things, he studied sample from the seabed, collected from the Challenger Expedition.
Described as a new species from Shinkolobwe, Democratic Republic of Congo by Schoep (1928). Later Deliens et al. (1990) argued that it was a mixture of dewindite and phosphuranylite. Sejkora et al. (2003) investigated specimens from Rýžoviště, Haarachov, Böhmen, Czech Republic and concluded that renardite is a valid species. However, further investigations are needed. Currently (2015), the species is listed by IMA as approved, but questionable, with a formula different from that of dewindtite.


The crystals of renardite described from Shinkolobwe resemble dewindite (Schoep, 1928).
