How Is Copper Formed? - Reference.com

Mar 30, 2020· How Is Copper Formed? Copper forms as molten rock with small amounts of copper fluid crystallizes. As the larger rock continues to solidify, the fluid rich in copper moves into cracks, eventually solidifying as well. Because the copper solidifies later than other minerals within the larger rock, the final deposits have a high concentration.

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.
