Addressing ore formation and exploration
Geoscience Frontiers, 2019 Abstract Common base and noble metals represent an important economic factor in the actual industrial development. For instance the world resources for copper are actually estimated for about the next 30 years only. The situation requires rethinking the way major ore deposits form, leading to new guides for exploration.
