Lannonite refers to a rare mineral that belongs to the sulfate family. It was discovered in Lannon, Waukesha County, Wisconsin, United States, and derived its name from its place of origin. This mineral typically forms as an efflorescence on mine timbers in underground coal mines and is predominantly found in association with pyrite and marcasite.
In terms of its physical characteristics, lannonite typically appears as a white, yellow, or pale blue crystalline substance with a vitreous to pearly luster. It possesses a monoclinic crystal system, with thin, tabular or platy crystal habits. Lannonite can also be found in the form of crusts or powdery aggregates.
Chemically, lannonite is a sulfate mineral composed of the elements lead, hydrogen, sulfur, and oxygen, with its chemical formula being Pb2O(SO4)(OH)2. It is considered a secondary mineral, meaning it forms as a result of chemical reactions and alteration of other minerals in the presence of water.
Due to its scarcity and the limited number of occurrences worldwide, lannonite does not hold significant economic importance. However, it is highly sought after by mineral collectors due to its unique crystal habits and rarity. Its striking colors and translucent appearance make it an attractive addition to any mineral collection.
Overall, lannonite is a remarkable mineral known for its intriguing formation process and aesthetically pleasing qualities, making it a topic of interest among mineral enthusiasts and researchers alike.
