Natromarkeyite

Na2Ca8(UO2)4(CO3)13(H2O)24·3H2O

Natromarkeyite is a rare hydrated uranyl carbonate mineral with the chemical formula Na2Ca8(UO2)4(CO3)13(H2O)24·3H2O. It belongs to the orthorhombic crystal system and is classified as a uranyl carbonate. The mineral is characterized by its yellow to greenish-yellow color, a vitreous to pearly luster, and a relatively low hardness on the Mohs scale. It has a low to moderate density and is typically found in uranium-rich environments. Natromarkeyite is part of a broader group of secondary uranium minerals formed through the alteration of primary uranium-bearing minerals.

Overview

Natromarkeyite is a rare hydrated uranyl carbonate mineral with the chemical formula Na2Ca8(UO2)4(CO3)13(H2O)24·3H2O. It belongs to the orthorhombic crystal system and is classified as a uranyl carbonate. The mineral is characterized by its yellow to greenish-yellow color, a vitreous to pearly luster, and a relatively low hardness on the Mohs scale. It has a low to moderate density and is typically found in uranium-rich environments. Natromarkeyite is part of a broader group of secondary uranium minerals formed through the alteration of primary uranium-bearing minerals.

Etymology

Natromarkeyite is named after the element sodium, which is a key component of its chemical composition. The name reflects the mineral's sodium content and honors the element's role in its structure.

How to recognize it

Natromarkeyite can be identified by its yellow to greenish-yellow color and vitreous luster. It has a relatively low hardness, though the exact Mohs value is not specified. The mineral is typically soft enough to be scratched by a copper coin. It may leave a white streak when rubbed on a porcelain plate. Its identification can be challenging due to its similarity to other uranyl carbonate minerals, but its distinct chemical composition and crystal system can aid in differentiation.

Trivia

Natromarkeyite is notable for its complex chemical formula, which includes a high number of water molecules and carbonate ions. The mineral is one of the few known uranium-bearing minerals that incorporate significant amounts of sodium. Its orthorhombic crystal system is relatively uncommon among uranyl carbonates, making it a subject of interest for mineralogical study.
