Azurite The blue gem material ore of copper and pigment

Geologic Occurrence Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores The carbonic acid of these waters dissolves small amounts of copper from the ore The dissolved copper is transported with the water until it reaches a new geochemical environment Get price
