UM1956-02-SiO:CaHU

This page is currently not sponsored. Click here to sponsor this page.
Formula:
CaUSiO6 · H2O
the above is the simplified form of Ca(UO2)(SiO4)•H2O
Reported as "Mineral B", as a part of composition of gummite (see also UM1956-01-O:HPbU). The Ca analogue of kasolite. Chemically similar to calcioursilite, haiweeite, metahaiweeite, uranophane, and uranophane-β.

Localitites include the Bob Ingersoll pegmatite, Pennington County, South Dakota; the Ruggles pegmatite, Grafton Center area, and the Beryl Mountain pegmatite near Acworth, New Hampshire; the Mica Lake area, Hahn's Peak, Colorado; Bisundi, Rajputana, India; possibly also from Karelia, Russia.
