Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
|Tract name||Deposit type||Geology|
|Manchuride||porphyry copper||An assemblage of Jurassic and Cretaceous post-subduction volcanic and intrusive rocks in northeast China and parts of Russian Federation, Mongolia, and North Korea|
|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.|
|Gobi-Amur||porphyry copper||Cambrian through Early Devonian igneous rocks that consist mostly of continental-margin arc rocks with some island-arc rocks at the eastern end; mostly covered by the Late Paleozoic Kazakh-Mongol Arc|
|Oyu Tolgoi||porphyry copper||A varied assemblage of Devonian through Triassic igneous rocks that include the Devonian Kazakh-Mongol continental-margin arc, as well as younger rocks related to the Indosinian orogeny (collision of China with Asia)|
