Liebigite is a mineral that belongs to the uranyl sulfate group. The word is spelled /liːbɪɡaɪt/ in IPA phonetic transcription. The first part of the word is pronounced as "lee," followed by "big" and "ite" pronounced as "bye" and "ite." The term was named after the German chemist Justus von Liebig, known for his pioneering work in organic chemistry. Liebigite is a rare mineral that may be found in uranium deposits formed in arid climates.
Liebigite is a rare mineral that occurs typically in the oxidation zone of copper deposits, particularly in arid regions. It is a secondary mineral formed by the weathering and alteration of primary copper minerals. The name Liebigite is derived from the renowned German chemist Justus von Liebig, who made significant contributions to the field of chemistry during the 19th century.
Chemically, Liebigite is classified as a copper uranyl sulfate hydroxide. It has a chemical formula of Cu2(UO2)2(SO4)2(OH)2·7H2O, indicating its composition consisting of copper, uranium, oxygen, hydrogen, sulfur, and water molecules. Its distinctive bright to pale green color is due to the presence of copper ions.
In terms of its physical properties, Liebigite typically crystallizes in the orthorhombic crystal system, forming prismatic crystals or crust-like masses. It has a relatively low hardness rating of 2.5 on the Mohs scale, making it relatively soft. Its luster is vitreous to silky, and it commonly exhibits a light green streak.
Liebigite is primarily sought after by mineral collectors for its aesthetic appeal and scarcity. Due to its association with copper deposits, it often occurs alongside other secondary copper minerals such as malachite, azurite, and chrysocolla.
Overall, liebigite is a fascinating mineral with a unique composition and occurrence, making it an intriguing subject of study for both mineralogists and collectors alike.
The word "liebigite" has its origin in the name of the German chemist Justus von Liebig (1803-1873), who made significant contributions to the field of chemistry. Liebig is particularly known for his research on organic compounds and agricultural chemistry. "Liebigite" is a mineral, specifically a hydrous uranium oxide carbonate, which was named in honor of Justus von Liebig for his achievements in the field of chemistry.
