Pseudojohannite
Pseudojohannite is a rare hydrated copper uranyl hydroxysulfate mineral with the chemical formula Cu3(OH)2[(UO2)4(SO4)2]·12H2O. It belongs to the triclinic crystal system and is classified under the Strunz system as 7.EC.20. This mineral is characterized by its soft, low hardness, and relatively low density, with a dull to vitreous luster. It typically exhibits a greenish or yellowish coloration. Pseudojohannite is a secondary mineral, often forming in uranium-rich environments, and is part of the broader group of uranyl hydroxysulfates.
Overview
Pseudojohannite is a rare hydrated copper uranyl hydroxysulfate mineral with the chemical formula Cu3(OH)2[(UO2)4(SO4)2]·12H2O. It belongs to the triclinic crystal system and is classified under the Strunz system as 7.EC.20. This mineral is characterized by its soft, low hardness, and relatively low density, with a dull to vitreous luster. It typically exhibits a greenish or yellowish coloration. Pseudojohannite is a secondary mineral, often forming in uranium-rich environments, and is part of the broader group of uranyl hydroxysulfates.
Etymology
The name 'pseudojohannite' is derived from the Greek 'pseudo-' meaning 'false' and 'johannite,' indicating a mineral that is similar to but distinct from johannite. The name reflects its structural or compositional resemblance to the mineral johannite.
Geological genesis
Pseudojohannite is a secondary mineral that forms through the alteration of uranium-bearing primary minerals, typically in oxidizing environments. It is commonly associated with the weathering of uranium-rich ores and is a product of hydrothermal or supergene processes involving uranyl compounds.
How to recognize it
Pseudojohannite can be identified by its low hardness, which is below 2.5 on the Mohs scale, and its soft, easily scratched surface. It exhibits a greenish or yellowish color and a dull to vitreous luster. The mineral has a low density and may be distinguished from other uranyl hydroxysulfates by its specific chemical composition and crystal system. It is often confused with similar hydrated uranyl minerals due to overlapping physical properties.
Host rocks
Pseudojohannite is typically found in uranium-rich secondary environments, such as oxidized zones of uranium deposits. It commonly occurs in association with other secondary uranium minerals and is often found in weathered or altered uranium-bearing rocks.
Trivia
Pseudojohannite is notable for its complex chemical formula, which includes both uranyl and sulfate groups along with a high water content. Its name suggests a close relationship to johannite, though it is chemically and structurally distinct. The mineral is also rare, with few documented occurrences, making it of interest to mineral collectors and researchers.
