Sydney, 08.07.2020 (SciDev.Net): Scientists have discovered a new tool to predict the location of base metal deposits, which are buried too deep beneath the Earth’s surface to be found using current exploration methods. This augurs well for targeted mining of metals, such as copper, lead, zinc, which are much in demand for their use in renewable energies.
The study, published on 29th June 2020 in the journal Nature Geoscience, found that 85 percent of all known base metal deposits and 100 percent of all “giant” deposits (those holding more than 10 million tons of metal) hosted in sedimentary basins are located on the edges of cratons – older regions of the continents, which are generally on thicker lithosphere, the rigid outermost cladding of the planet comprising the crust and upper mantle.
