Monument at Ningyo Pass, Japan
Formula:
(U,Ca,Ce)2(PO4)2 · 1-2H2O
Colour:
Brownish green to brown
Hardness:
3 - 4
Crystal System:
Orthorhombic
Name:
Named in 1959 by Tadashi Muto, Robert Meyrowitz, Alfred M. Pommer, and Toru Murano for the Ningyo Pass, Japan, where the country's largest uranium deposit and type locality mine are located.
A potential Fe-Th-REE analogue is known as 'UM1979-10-PO:FeHREETh'. Also comparable to 'UM1980-04-PO:CaHREETh'.
