About RenarditeHide

Alphonse François Renard
Specific Gravity:
Crystal System:
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 dewindtite 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).
