2021-9-12 · Copper deposits were formed by the action of hot waters commonly associated with volcanism but also with sediments and can be found around the world on every continent Copper can be found in the earth’s crust as pure native copper but mostly occurs in combination with other elements. More Detail.

How Is Copper Formed? - Reference

2020-3-30 · 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.
