Answer:
Here you go, info bomb.
Explanation: The project, funded by Anglo American, a major global mining company, compared the chemical compositions of minerals from magmatic rocks that host porphyry deposits against those which are barren. A case study was then undertaken of a major new porphyry discovery in Chile, to test their theory. Minerals from magmatic rocks which host porphyry deposits have distinctive chemical characteristics which can be used as one of a suite of indicators to home-in on porphyry deposits. Unravelling the causes of the distinctive chemical signatures has also brought new insights into the formation of porphyry copper deposits, and more generally the generation of the magmatic rocks from which they form, which are an important component of the Earth's crust. The main finding in this regard is that the magma chamber below the porphyry undergoes discrete injections of water-rich melts or watery fluids which enhance the magma's ability to transfer copper and other metals upwards to form a porphyry copper deposit.
Dr Ben Williamson, of the University of Exeter's Camborne School of Mines, said: "This new method will add to the range of tools available to exploration companies to discover new porphyry copper deposits. Our findings also provide important insights into why some magmas are more likely to produce porphyry copper deposits than others, and add to our understanding of how their parent magmatic rocks evolve."
Answer:
Search for rocks that are green or pieces of ore that have green flecks. The green hue is characteristic of copper. Remove samples of the rocks and take them back to the lab for testing. If the rocks have a high part per million counts of copper, then you may have found a copper deposit.
Explanation:
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.
