About MagnioursiliteHide

Formula:
Mg4(UO2)4(Si2O5)5(OH)6 · 20H2O
Colour:
Lemon-yellow
Hardness:
3
Specific Gravity:
3.254
Name:
Named for its chemical composition as a magnesium uranyl silicate.
Magnioursilite was originally described in 1957 as “ursilite” (now discredited) from the Oktyabr’skoye deposit, Kyzyltyube-Saj, Samgar Steppe, Tajikistan.

Forms a solid solution with calcioursilite.
