Modeling magma to find copper
Copper is an essential element of our society with main uses in the field of electricity and electronics. About 70% of the copper comes from deposits formed several million years ago during events of magma degassing within Earth’s crust just above subduction zones. Despite similar ore forming processes, the size of these deposits can vary orders of magnitude from one place to another, the main reason of which has remained unclear. A new study suggests that the answer may come from the volume of magma emplaced in the crust and proposes an innovative method to better explore these deposits.
