danielsite

Danielsite is a sulfide and sulfosalt that was first discovered in a pocket of supergene minerals in the north region of Western Australia. The location found was about west of the locality known as Coppin Pool. The mineral danielsite was named after John L. Daniels who collected the sample in which the new mineral was found. The chemical formula of danielsite is . Danielsite is very fine grained and hard to observe in hand samples. It generally has a gray color with very brittle and soft physical characteristics.

== Occurrence == Danielsite occurs in the mineral anglesite as ragged polycrystalline masses typically intergrown with covellite, stromeyerite, and chalcocite. The size of these masses is typically across. Due to its occurrence with stromeyerite it is thought to possibly be a polymorphic replacement of galena. Danielsite was found in a gossaniferous pod in a white quartz vein. It has been found near Coppin Pool, Ashburton Shire, Western Australia, Australia, Austria, and Belgium.
