RM2089   Cuprian dundasite

Prullans, La Cerdanya, Catalunya, Spain

Dundasite is an unusual lead and aluminum hydroxycarbonate, which is formed as a secondary mineral in the oxidation zone of lead deposits. This Pyrenean locality is very interesting for its diverse paragenesis. In this specimen we observe under the magnifying glass numerous and aesthetic aggregates of dundasite as acicular crystals of silky luster, some slightly bluish due to their Cu content, contrasting on the matrix.
