Azurmalachite - a rock composed of azurite and malachite. The host rock is often a limestone, in this case it's a dolostone (a fine-grained sedimentary rock composed primarily of dolomite). This neutralize the slightly acidic waters and facilitate precipitation of the dissolved copper in the form of carbonate minerals in fractures, cavities, and pore spaces.
