Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
| Tract name | Deposit type | Geology |
|---|
| Gangdese | porphyry copper | A linear belt of Oligocene and Miocene post-subduction igneous rocks in southwest China |
| Qinling-Dabie | porphyry copper | Cambro-Ordovician island arc, Devonian continental-margin arc related to northward Paleo-Tethyan ocean subduction under North China, Qaidam, and Tarim Cratons, and Permo-Triassic rocks formed by collision of North China and Tarim cratons with Eurasia |
| Jinsajiang | porphyry copper | Carboniferous through Triassic rocks that were formed as continental arcs by subduction of the Paleotethyan oceanic crust southward below Qiangtang (North Tibet) terrane and northward below north China. |
| Tethyan Gangdese | porphyry copper | Late Triassic, Yanshanian (Jurassic and Cretaceous) and early Tertiary igneous rocks in southwestern China that were formed during subduction of the Tethyan ocean below the southern margin of Asia |
