Detailed explanation-1: -The magmas responsible for porphyry formation are conventionally thought to be generated by the partial melting of the upper part of post-subduction, stalled slabs that are altered by seawater.
Detailed explanation-2: -Tectonic setting of porphyry copper and epithermal ore deposits. Porphyry copper, skarn and epithermal ore deposits are the most common type of hydrothermal ore deposits. They are genetically linked to convergent tectonic margins characterized by calcalkaline magmatism.
Detailed explanation-3: -Copper is a metal that has been deposited from hot sulphur solutions, created in volcanic regions. The hot solutions concentrated the copper up to a thousand times more than would normally be found in rocks. The resultant enriched rocks are called copper ores.
