Copper comes from thermal fluid, mainly composed of water, and is released by cooled magma. These magma, which is also the basis of eruption, comes from the middle layer between the earth’s core and crust, that is, the mantle, and then rises to the earth’s surface to form a magma chamber. The depth of this room is generally between 5km and 15km.

The formation of copper deposits takes tens of thousands to hundreds of thousands of years, and volcanic eruptions are more frequent. a failed eruption depends on a combination of several parameters the rate of magma injection, the rate of cooling and the hardness of the crust surrounding the magma chamber.

The discovery of the similarity between large volcanic eruptions and sediments will make it possible to use the vast knowledge gained by volcanologists to advance the current understanding of the formation of porphyry sediments.
