Anglesite crystals from Touissit, Morocco – micromount as unique piece
This micromount features several well developed Anglesite crystals ranging from translucent to transparent, displaying yellow to honey colored tones. The crystals are steeply grown, partly tabular in habit, and rest on a dark, compact matrix. Crystal faces are well defined and show a vitreous luster. Despite the small size, the crystal morphology is clearly developed and mineralogically well identifiable. Crystals are clearly recognizable and dominate the visual character of this specimen.
Geology & Origin
Anglesite is a lead sulfate that forms as a secondary mineral through the oxidation of primary lead sulfides, especially Galena, within the oxidation zones of lead deposits. The Touissit deposit in Morocco is a classic locality for secondary lead minerals and is well known for producing high quality Anglesite crystals. Crystal formation occurs under oxidizing conditions when sulfide rich ores interact with oxygenated groundwater. Specimens from Touissit are highly regarded by collectors worldwide for their well defined crystal habits and characteristic coloration.
