Plumbonacrite
Plumbonacrite is a rare lead carbonate hydroxide mineral with the chemical formula Pb5(CO3)3O(OH)2. It belongs to the trigonal crystal system and is classified under the Strunz system as 5.BE.15. This mineral is typically found in oxidized zones of lead deposits and is characterized by its white to pale yellow color, a vitreous to pearly luster, and a relatively low hardness of approximately 3.5 to 4 on the Mohs scale. It has a specific gravity of around 5.5 to 6.0, making it moderately dense. Plumbonacrite is part of the carbonate mineral group and is notable for its complex chemical composition, which includes lead, carbonate, and hydroxide ions.

Overview
Plumbonacrite is a rare lead carbonate hydroxide mineral with the chemical formula Pb5(CO3)3O(OH)2. It belongs to the trigonal crystal system and is classified under the Strunz system as 5.BE.15. This mineral is typically found in oxidized zones of lead deposits and is characterized by its white to pale yellow color, a vitreous to pearly luster, and a relatively low hardness of approximately 3.5 to 4 on the Mohs scale. It has a specific gravity of around 5.5 to 6.0, making it moderately dense. Plumbonacrite is part of the carbonate mineral group and is notable for its complex chemical composition, which includes lead, carbonate, and hydroxide ions.
Etymology
The name plumbonacrite is derived from the Latin word 'plumbum,' meaning lead, in reference to its lead content. The name highlights the mineral's chemical composition and its association with lead-bearing environments.
Geological genesis
Plumbonacrite forms in the oxidized zones of lead deposits, typically as a secondary mineral. It is a product of the alteration of primary lead sulfides in the presence of carbon dioxide and water, which leads to the formation of lead carbonate hydroxide minerals. Its genesis is closely tied to the weathering and oxidation processes in lead-rich environments.
How to recognize it
Plumbonacrite can be identified by its low hardness of 3.5 to 4 on the Mohs scale, which allows it to be scratched by a copper coin or a knife blade. It typically exhibits a white to pale yellow color and a vitreous to pearly luster. The mineral has a white streak and a specific gravity of 5.5 to 6.0, which is relatively high for a carbonate mineral. It is often confused with other lead carbonate minerals, but its unique chemical composition and crystal habit can help distinguish it.
Host rocks
Plumbonacrite is typically found in oxidized zones of lead deposits, often associated with other secondary lead minerals. It forms in the weathering and oxidation environments of primary lead sulfide ores, such as galena, in the presence of carbon dioxide and water.
Trivia
Plumbonacrite is notable for its rare occurrence and complex chemical formula, which includes lead, carbonate, and hydroxide ions. It is a member of the trigonal crystal system, which is less common among carbonate minerals. The mineral's name is directly linked to its lead content, emphasizing its geochemical significance in lead-rich environments.
