Autunites are a type of mineral that belong to the autunite group, named after the town of Autun in France where the first samples were discovered. These minerals are classified as phosphates and are known for their bright yellow to green fluorescent color under ultraviolet light.
Physical Properties
Autunites have a distinctive square or rectangular prismatic crystal structure with a high luster. They are typically transparent to translucent with a hardness of 2.5 to 3 on the Mohs scale. The chemical formula for autunites is generally (Ca, Pb)2(UO2)2(PO4)2•x(H2O), indicating the presence of calcium, lead, uranium oxide, phosphate, and water molecules in their composition.
Occurrence
Autunites are primarily found in hydrothermal veins, granite pegmatites, and uranium deposits around the world. They are often associated with other uranium minerals such as torbernite and meta-autunite. These minerals can also form as secondary deposits through the alteration of primary uranium ores.
Uses
Due to their uranium content, autunites have been used in the past as a uranium ore for nuclear fuel production. However, their radioactive nature and low uranium concentration limit their commercial utility. Autunites are more commonly collected as mineral specimens for their vibrant fluorescence and unique crystal forms. They are also studied for their geological significance in understanding uranium mineralization processes.
Autunites are fascinating minerals that exhibit both beauty and scientific importance. Their distinctive properties make them valuable to collectors and researchers alike, offering insights into the world of uranium mineralogy.
Overall, autunites are a captivating mineral group that continues to intrigue geologists and mineral enthusiasts around the globe.
