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|
