ITEM# MINERAL-Orpiment-0001
Orpiment, As2S3, is a common monoclinic arsenic sulfide mineral.
Orpiment is an orange to yellow mineral that is found worldwide, and occurs as a sublimation product in volcanic fumaroles, low temperature hydrothermal veins, hot springs and as a byproduct of the decay of another arsenic mineral, realgar.
Realgar, As4S4, a form of arsenic sulfide, is also known as "ruby sulphur" or "ruby of arsenic". It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment as it is here. Realgar is orange-red in color.
Realgar most commonly occurs as a low-temperature hydrothermal vein mineral associated with other arsenic and antimony minerals. It also occurs as volcanic sublimations and in hot spring deposits. It occurs in association with orpiment, arsenolite, calcite, and barite.
It is found with lead, silver and gold ores in Hungary, Bohemia, and Saxony. In the US it occurs notably in Mecur, Utah; Manhattan, Nevada, and in the geyser deposits of Yellowstone National Park.
This specimen is mounted on a clear polycarbonate base and measures approximately 1 inch on a side.
