System:OrthorhombicColour:Bright yellow; deep ...
Hardness:2½
Name:In allusion to the composition, being a PHOSPHate of URANYL uranium.


See also the closely related Yingjiangite.

NOTE: Modern analytical techniques applied to specimens of "phosphuranylite" in the Joseph Cilen 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.
