Tempo of magma degassing and the genesis of porphyry copper deposits [PDF]
Scientific Reports, 2017 Abstract Porphyry deposits are copper-rich orebodies formed by precipitation of metal sulphides from hydrothermal fluids released from magmatic intrusions that cooled at depth within the Earth’s crust. Finding new porphyry deposits is essential because they are our largest source of copper and they also contain other strategic metals ...
