Porphyry copper deposits are largely produced by mechanisms similar to those causing large volcanic eruptions, new research by the University of Geneva has found. In a paper published in the journal Communications Earth & Environment, the scientists behind the discovery say that at a time when copper resources are dwindling, their finding opens up new avenues for the development of tools to find new deposits. To reach their conclusion, the experts relied on data and figures provided by mining companies and on those collected in the field and in the laboratory by numerous researchers—combined with petrological and ...
