Manganoan Adamite Mineral Photos and Locations

Manganoan Adamite, also known as Manganadamite, is a pink to purple variety of Adamite containing some manganese. This manganese gives Manganoan Adamite its distinct pink to purple color. Adamite is one of the best fluorescent minerals but Manganoan Adamite does not fluoresce because the manganese kills the fluorescence. This is not a foolproof test as some Adamites that contain little or no manganese do not fluoresce either. Nearly all other properties of Manganoan Adamite are identical to Adamite except typical color, density and fluorescence. There is a green variety of Adamite called Cuprian Adamite, or Cuproadamite, that is colored by its copper content.

Distribution: In Greece at Lavrion District Mines, Lavrion District, Attikí Prefecture. In Mexico at the Ojuela Mine, Mapimí, Mun. de Mapimí, Durango. In the USA at the Gold Hill Mine, Gold Hill, Clifton District, Deep Creek Mts, Tooele County, Utah.
