About Phosphuranylite
Formula:
KCa(H3O)3(UO2)7(PO4)4O4 · 8H2O
Colour:
Bright yellow; deep golden-yellow, honey-yellow
Lustre:
Sub-Vitreous, Resinous, Waxy, Silky
Hardness:
2½
Crystal System:
Orthorhombic
Member of:
Name:
Named in 1879 by Frederick A. Genth in allusion to the chemical composition, being a PHOSPHate of URANYL uranium.
Isostructural with:
Small crystals may have thin rectangular bladed habit. See also the closely related yingjiangite and dewindtite.
NOTE: Modern analytical techniques applied to specimens of "phosphuranylite" in the Joseph Cilen [1916-1997] collection, Hawthorne, NJ, USA, accumulated over a period of 50 years, and containing many older specimens, identified yingjiangite in many instances (Chet Lemanski).
A secondary mineral commonly occurring in weathered zones of granite pegmatites, coating fissures near altered uraninite, and in paleochannel deposits in sandstone. Frequently present in an alteration halo around uraninite/pitchblende found in granite pegmatites. The uraninite may have in contact one of more various schoepite group minerals. Dark yellow phosphuranylite may be found as a coating on a fracture around black uraninite at several to many diameters of the core uraninite grains. Autunite group minerals are in an outer ring that may overlap with the phosphuranylite.
