Anglesite is a rare lead sulfate mineral that is found in various parts of the world. It is named after the town of Anglesey in Wales, where it was first discovered. Anglesite is a popular collector's mineral due to its unique crystal structure and physical properties.
History
Anglesite was first discovered in 1803 by the Welsh mineralogist William Withering. He named the mineral after the location where it was found, Anglesey in Wales. The first specimens of Anglesite were found in the Parys Mountain copper mine, which was known for its rich deposits of various minerals.
Geology
Anglesite is a secondary mineral that forms as a result of the oxidation of lead sulfide minerals in lead deposits. It is often found in the oxidized zone of lead deposits, where it forms as a result of the reaction between lead sulfide minerals and oxygen-rich groundwater. Anglesite is also found in the weathering zone of lead deposits, where it forms as a result of the weathering of galena, a lead sulfide mineral.
Properties
Anglesite has a unique crystal structure that makes it a popular collector's mineral. It forms in orthorhombic crystals, which are characterized by their three unequal axes. The crystals of Anglesite are usually short and prismatic, with a square or rectangular cross-section. They are often translucent to transparent, with a vitreous to adamantine luster. The color of Anglesite varies from colorless to white, gray, yellow, green, and brown.
Anglesite has a Mohs hardness of 2.5 to 3, which makes it a relatively soft mineral. It has a specific gravity of 6.3 to 6.4, which makes it one of the heaviest lead minerals. Anglesite is also fluorescent, which means that it glows under ultraviolet light.
Uses
Anglesite is a popular collector's mineral due to its unique crystal structure and physical properties. It is also used in various fields due to its properties. Here are some of its uses:
Lead Ore: Anglesite is an important ore of lead, which is used in various applications, such as batteries, ammunition, and plumbing.
Pigment: Anglesite is used as a pigment in the production of white paint and ceramics.
Radiation Shielding: Anglesite is used as a radiation shielding material due to its high density and ability to absorb radiation.
Jewelry: Anglesite is used in the production of jewelry due to its unique crystal structure and beautiful colors.
Spiritual Healing: Anglesite is believed to have spiritual and healing properties. It is often used in crystal healing and meditation practices to promote relaxation, calmness, and inner peace.
Conclusion
Anglesite is a rare lead sulfate mineral that is prized for its unique crystal structure and physical properties. It is a popular collector's mineral and is used in various fields, such as lead ore production, pigment production, radiation shielding, jewelry production, and spiritual healing practices. The history, geology, properties, and uses of Anglesite make it a fascinating mineral to study and appreciate.
