Massive Jarosite Southwest mine Specimen 6.5cm Graeme collection Douglas Graeme photo

Malachite with a wide, undulating horizontal band reflecting a solution level with malachite deposition, which indicates the stalactites had been submerged at some point. The malachite stalactites are almost completely encrusted with small malachite pseudomorphs after azurite. Azurite, as a few, unaltered crystals of the same morphology are scattered about on the malachite above the solution level, suggesting that the CO2 levels of the open space were higher than in the solutions.
