About SpriggiteHide

Reginald C. Sprigg
Pb3(UO2)6O8(OH)2 · 3H2O
Bright orange
Specific Gravity:
Crystal System:
Named in honor of Reginald Claude Sprigg (1 March 1919, Yorketown, South Australia, Australia - 2 December 1994, Glasgow, Scotland), government geologist in South Australia, and conservationalist. He discovered the Pre-Cambrian fossils at Ediacara Hills and is co-author of "Uranium deposits of South Australia". He also founded the popular Arkaroola Wilderness Sanctuary.
Sheets in the structure are similar to those in ianthinite, rameauite, and wyartite.
