Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Northern Carpathians | porphyry copper | An arcuate belt of calc-alkaline volcanic and intrusive rocks that formed in a post-subduction setting due to extension, lithospheric thinning, and mantle upwelling. |
| Southern and Central European Variscan | porphyry copper | Discrete areas of intrusive and volcanic rocks of Variscan age, where some evidence of porphyry-style hydrothermal activity is preserved. |
| Pacific Margin | porphyry copper | Cretaceous through middle Tertiary volcanic and intrusive rocks representing a series of continental- and island-arc systems accreted and superimposed onto the paleomargin of northeast Asia. |
