TitleRosasite and calcite
DescriptionRosasite, (Cu,Zn)2CO3(OH)2, forms in the oxidation zones of zinc-copper deposits. It typically is found as attractive bluish-green crusts and forms botryoidal masses or nodules. Crystals also may be fibrous and in tufted aggregates. Rosasite is associated with red limonite and other such colorful minerals as aurichalcite, smithsonite and hemimorphite. Here it is also seen with white and gray crystals of calcite. This sample is 9 cm across.
