Rosasite Mineral Specimen #7
The forest-green color of the rosasite indicates and unusually high zinc content. The rosasite rests atop a matrix of massive, orange-brown limonite. This orange-brown matrix is an identifying characteristic of virtually all oxidized-mineral specimens from the Ojuela Mine. A great addition to any mineral collection.
This month’s featured mineral is rosasite for the Ojuela Mine at Mapimi, Mexico. We have never before featured this uncommon basic copper zinc carbonate as our Mineral of the Month.
Rosasite in named after the Rosas Mine in Sardinia, Italy, where it was first discovered.
