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.|
