scorzanelite

Scorzanelite is a mineral species with the chemical formula Pb(CrO4)2. It is a lead chromate mineral that is found as a secondary mineral in oxidized lead deposits. Scorzanelite typically occurs in association with other lead and chromium minerals such as crocoite, phoenixite, and chromian anglesite. It is known for its vibrant orange-red to yellow coloration and its vitreous luster. The crystal habit of scorzanelite is usually prismatic or acicular, forming needle-like crystals.

The mineral was first discovered in the Tintic Standard Mine in Utah, United States, and was named in honor of Robert M. Scorza, an American mineral collector and dealer. The discovery occurred in the early 21st century. Scorzanelite is relatively rare and is primarily of interest to mineral collectors and researchers due to its distinctive chemical composition and vivid color. Its formation requires specific geological conditions, typically involving the oxidation of lead sulfide minerals in the presence of chromium-bearing solutions.
