A new method of low cost for porphyry copper deposits

A cooperative study funded by the British and American group found a low cost approach to the discovery of porphyry copper deposits.

On February 1, Dr. Richard Harrington of the University of Exeter Camborne School of Mines Ben Williamson (Ben Williamson, and London's Natural History Museum (Richard Harrington) together all the published in Nature Geoscience sites. In this paper, a simple method to find the porphyry copper deposit is introduced in detail.

Porphyry copper deposits accounted for 75% of the world's copper reserves, 50% of molybdenum and 20% of gold. However, the surface can be found in the porphyry copper ore looking for almost, the next step to look for concealed deposits.

The researchers have made an empirical study of the newly discovered porphyry deposits in Chile, and compared the difference of the chemical compositions between the mineralized porphyry bodies and the. This method can be used to find the deep.

Dr Williamson said their results explain why some magma eventually evolved into a copper bearing porphyry, and how the parent rock evolved.

The study of magmatic rock chemical composition index to verify the existing metallogenic theory: mineral rich a small amount of water fluid into a pool of magma, copper and other minerals to migration, in several kilometers below the surface of magmatic rocks formed porphyry deposit.

Magmatic rocks play an important role in the formation of the earth's crust.
