- The next morning we drove west to the famous town of Shimen, the locality for all the superb realgar and orpiment crystals.
- It is an alteration product of realgar, native arsenic, and, less commonly, arsenopyrite.
- Even the arsenic mine at Shimen, Hunan Province, is still the source of minor amounts of good realgar, orpiment, and calcite.
- Orpiment and realgar are yellow and orange mineral species of arsenic sulphide, used in 16th-century Venetian painting particularly, but at various other times also.
- Unfortunately, however, many orpiment localities also contain abundant to trace realgar, sometimes intimately intergrown with the orpiment, leading to overall specimen stability problems.
- A number of relatively minor yet interesting California realgar localities are given by Murdoch and Webb.
- The specimen was a classic Lengenbach assemblage: sugary white dolomite matrix, realgar, minor pyrite, and a massive metallic gray sulfosalt that had been labeled as ‘sartorite.’
- Small amounts of realgar have been reported from a large number of European occurrences, generally related to relatively recent volcanism, limestone or dolomite quarries, or base- and precious-metal deposits.
