Formation of giant iron oxide-copper-gold deposits by superimposed episodic hydrothermal pulses. [PDF]

Sci Rep, 2023
Iron oxide-copper-gold (IOCG) deposits are a globally important source of copper, gold and critical commodities. Despite their relevance, IOCG deposits remain an ill-defined clan, with a range of characteristics that has complicated development of the ...

Lithospheric conductors reveal source regions of convergent margin mineral systems. [PDF]

Sci Rep, 2022
The clean energy transition will require a vast increase in metal supply, yet new mineral deposit discoveries are declining, due in part to challenges associated with exploring under sedimentary and volcanic cover.

Contrasting magma chemistry in the Candelaria IOCG district caused by changing tectonic regimes. [PDF]

Sci Rep
Iron oxide-copper-gold (IOCG) deposits are a vital source of copper and critical elements for emerging clean technologies. Andean-type IOCG deposits form in continental arcs undergoing extension, and they have a temporal relationship with magmatism ...

Mantle-derived fluid flux controls Olympic Dam-style Fe oxide-Cu-Au mineralisation. [PDF]

Sci Rep
Conventional mineral exploration has focused on processes in the mid-upper crust, however recent advances in the geophysical and geochemical understanding of the sub-continental lithospheric mantle (SCLM) suggest that the macroscopic architecture of the ...

New insights into the genesis of IOCG deposits: From a case study of the Yinachang deposit in SW China

Ore Geology Reviews, 2020
Abstract The Yinachang Fe-Cu-Au-U-REE deposit is hosted by the lower part of the Paleoproterozoic Kunyang Group in the central Yunnan Province of SW China in an area known to contain iron-oxide Cu-Au mineralisation. The deposit includes: (i) the sulphide assemblage chalcopyrite – pyrite – magnetite – cobaltite – molybdenite – cassiterite; (ii) Rare ...

Volcanogenic features of IOCG deposits of North Carajás, Brazil, and related constraining evidence

Journal of the Geological Survey of Brazil
The magnetitic Cu-Au (IOCG) deposits of north Carajás, Amazonian Craton, Brazil, are hosted in the Neoarchean (2.76 Ga), dominantly basaltic-greywacke Itacaiúnas metavolcanic-sedimentary sequence that evolved in a continental rift setting.

Withdrawn: Allanites in the Sin Quyen IOCG deposit, North Vietnam

, 2020
Allanite minerals are the principal host of REEs in the Sin Quyen, Iron Oxide Copper Gold (IOCG) type deposit. The studied allanites have concentrations of: REE (14-27 wt%), Ca (9-16 wt%), Al (8-19 wt%), Si (26-34 wt%) and Fe (12-21 wt%). Two populations of allanite are documented, the first is texturally older probably related to the Ca-K alteration ...
