Markeyite
Markeyite is a hydrated calcium uranyl carbonate mineral with the chemical formula Ca9(UO2)4(CO3)13·28H2O. It crystallizes in the orthorhombic system and belongs to the uranyl carbonate mineral group. The mineral is characterized by its low hardness, relatively low density, and vitreous to pearly luster. Its color is typically yellowish or greenish due to the presence of uranium. Markeyite is notable for its complex hydration and is commonly found in uranium-rich environments. It is a secondary mineral that forms under specific geochemical conditions.
