Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
|Tract name||Deposit type||Geology|
|Alaska Peninsula and Aleutian Islands||porphyry copper||Tertiary felsic to intermediate composition intrusions of the Alaska Peninsula and Aleutian Islands|
|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.|
|Kazakh-Tianshan||porphyry copper||Cambrian through Silurian igneous rocks (Kipchak and Stepnyak-North Tienshan island arcs) in the western part of the Central Asian Orogenic Belt. Partly covered by the Late Paleozoic Balkash-Yili Arc.|
|Kazakh-Tarim||porphyry copper||Devonian through Early Triassic igneous rocks that include the Balkash-Yili continental-margin arc and younger rocks related to the Indosinian orogeny (collision of China with Asia)|
