Massive Iron Oxide-Apatite (IOA) Deposit Formation by Efficient Flotation of Magmatic Magnetite Suspensions: A Genetic Link Between IOA and IOCG Deposits?
(2015)
The link between iron oxide-apatite (IOA, or
“Kiruna-type”) and iron oxide-copper-gold (IOCG) deposits
remains controversial. Based on geochemical and isotopic
data of magnetite from the Los Colorados IOA deposit in
northern ...
Remanence, self-demagnetization and their ramifications for magnetic modelling of iron oxide copper-gold deposits: An example from Candelaria, Chile
(Elsevier Science, 2014-10)
Magnetic modelling can be a powerful tool for understanding the architecture of numerous types of mineralized systems; e.g., iron ore, IOCG and porphyry deposits. In such modelling, the induced component is generally assumed ...

Modelo deposicional das formações ferríferas bandadas hospedeiras de ouro no greenstone belt arqueano Rio das Velhas, Quadrilátero Ferrífero, com base em geoquímica e análises in situ de magnetita por ablação a laser via ICP-MS
(Universidade Federal de Minas GeraisBrasilIGC - DEPARTAMENTO DE GEOLOGIAPrograma de Pós-Graduação em GeologiaUFMG, 2018-10-25)
Petrographic and geochemical studies were undertaken on some of the several Algoma-type banded iron formations from the Rio das Velhas greenstone belt, Quadrilátero Ferrífero, Brazil, including a number of samples from ...
Iron and oxygen isotope and element systematics of magnetite from the Los Colorados IOA deposit, Chile: A paradigm shift for IOA deposits?
(2014)
The origin of iron-oxide apatite (IOA) and iron-oxide copper gold deposits (IOCG) remains
debated, with few observational data able to distinguish among working hypotheses that invoke
meteoric fluid, magmatic-hydrothermal ...
Middle Proterozoic vein-hosted gold deposits in the Pontes e Lacerda region, southwestern Amazonian craton, Brazil
(1997-05-01)
Structural, geochemical, and isotope studies were carried out on the gold deposits of the Pontes e Lacerda region (Mato Grosso state, Brazil), where rocks of the Aguapei and Rondoniano mobile belts (southwestern Amazonian ...
