✪ Carnotite
Formula: K2(UO2)2(VO4)2 · 3H2O
Habit: Encrusttations on/in Sandstone, Limestone and Quartz.
Colour: Yellow, Bright Yellow
Description: Carnotite in the Maybell District is vibrant Yellow in Color. Crusts of Carnotite frequent the Sandstone, Limestone and Quartz which embody the majority of the bedrock. Not all Carnotite exhibits formations in this district, banding in the native sandstone and limestone is frequent. Confirmed, Maneotis:2009.
