PROGNOSTIC ESTIMATE OF NOBLEMETAL RESOURCES IN PROMISING ORE DISTRICTS OF THE KARELIAN REGION
The gold and platinoid resources of the Karelian region are expected to increase. Our prediction is based on the leading genetic types of noble-metal mineralization known in the region such as the low-sulphide Pt-Pd type in layered plutons and gabbro ...

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

Petrographic Evidences for the Origin of Iron in IOCG IronDeposits of Kuh-E-Faryadoon and Kouli-Kosh, Southeast Central Iran [PDF]
Kuh-E-Faryadoon and Kouli Kosh iron deposits are hosted by regional metamorphic rocks of Sanandaj-Sirjan zone around Deh-Bid area. Plugs and domes of acid rocks protrude these metamorphic rocks.

Apatite chemistry - a potential tool for IOCG exploration
Northern Norrbotten is an important mining region of Sweden and is regarded as an iron-oxide copper-gold (IOCG) district hosting several apatite-iron oxide and copper-gold sulphide ores (e.g. Hitzman et. al., 1992). The IOCG group of deposits is diverse with respect to age, host rock, ore and alteration mineralogy as well as ore-forming processes and ...
