Answer:
To understand how copper is formed, it helps to look at how porphyry deposits—the largest current sources of copper ore—form. The orebodies form in hydrothermal veins that are born in underground magma chambers far below the deposit itself. The high temperatures of volcanic magma create hydrothermal veins, allowing some of the heat to escape near the upper layers of the Earth’s crust.
This is why copper is often found in the sedimentary layer, where sand and mud are compressed until they form a layer of sedimentary rock on the surface of the earth. Copper ore gets trapped in oxidized zones within these types of rocks.
Copper is also commonly found in the oxidized zones of mineral deposits and in basalt cavities that have been in contact with hydrothermal veins. The presence of volcanoes in a region is often a good indicator of the presence of copper because that is where basalt cavities are in abundance near the sedimentary layer of the Earth.
