Anglesite is a mineral composed primarily of lead sulfate, with the chemical formula PbSO4. It typically forms in the oxidation zones of lead ore deposits and is often found alongside other minerals such as galena and cerussite. Anglesite can appear in various colors, including white, yellow, and gray, and it has a glassy to resinous luster. This mineral is known for its brittle nature and can be transparent to translucent. Anglesite is sometimes used as a minor ore of lead, although its primary significance lies in its role in understanding the processes of mineral formation and alteration in geological environments.
