The geological theory of Plate Tectonics and the Associated Mineralization Process relating to the formation of ore deposits is a hugely complicated process with the myriad contributing variables such as rock and fluid compositions, temperature, pressure pH, eH, structure and time, all interacting to provide a host of different outcomes.
6.2. Suitable tectonic setting for porphyry deposits of Iran. Porphyry copper mineralization in Iran, occurred over a long period of time from late Eocene (Priabonian, 39 Ma), in the Maher Abad deposit, East Iran, to late Miocene (Messinian, 6.19 Ma) in the Abdar deposit of the KPCB.
Ore Deposits and Plate Tectonics. Plate tectonics, like crustal evolution, provides a basis for understanding the distribution and origin of mineral and energy deposits.The relationship of plate tectonics and mineral deposits is significant on three counts: Geological processes operating due to energy released at plate boundaries control the process of mineral deposition.
Telethermal mineral ore deposit are formed at shallow depth and relatively low temperatures, with little or no wall-rock alteration, presumably far from the source of hydrothermal solutions. Ore deposits are usually classified by ore formation processes and geological setting.

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.. These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is 4500 kg/m 3.
Based on the geochemical characteristics and tectonic settings of the ore-bearing porphyries in the Gandise and Yulong metallogenic zones, it is proposed that delamination may be the important mechanism of formation of porphyry copper deposits.
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.

Jul 23, 2013· Porphyry copper deposits are typically very-low grade with between 0.4 and 1% copper. The main mineral is chalcopyrite, which is finely disseminated through the host porphyritic rocks. The only reason these ore bodies are economic is because porphyries are huge, with hundreds of millions of tonnes available in a fairly low-cost mining setting.

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
