#0183;#32;Iron oxidecoppergold (IOCG) deposits are a globally important but diverse group of hydrothermal ore deposits showing similarities to porphyry CuAu, sedimentary Cu and skarn deposits, reflecting variable fluid chemistry, links to intrusions and tectonic settings.
The iron oxide coppergold deposits (IOCG deposits) are being extensively and intensively studied abroad, but in China the study of such deposits is still in its beginning stage. In this paper, the authors present a review of the present research situation of the IOCG deposits, which includes definition of the iron oxide coppergold deposits, temporal and spatial distribution, oreforming
Mauritania hosts one significant coppergold deposit, Guelb Moghrein and several occurrences, which have been categorized as iron oxide coppergold (IOCG) deposits but which are atypical in some important respects. Nonetheless, Guelb Moghrein is an economically significant mineral deposit and an attractive exploration target.
Iron oxidecoppergold (IOCG) deposits are characterized by abundant lowTi iron oxide (magnetite and hematite), pervasive hydrothermal alkali (Na/Ca/K) alteration, and an extensional tectonic
The deposit is an iron oxide copper gold style mineralisation. The Olympic Dam mine works an extremely large iron oxide copper gold deposit with estimated reserves of billion tonnes of ore grading % copper, % uranium, .5 g/t of gold and 6 g/t of silver.
IOCG Deposit Types Definition Iron oxide coppergold (IOCG) deposits encompass a wide spectrum of sulphidedeficient lowTi magnetite and/or hematite ore bodies of hydrothermal origin where breccias, veins, disseminations and massive lenses with polymetallic enrichments (Cu,
Iron oxide copper gold ore deposits are important and highly valuable concentrations of copper, gold and uranium. With an tendancy for being tremendous in size, relatively simple metallurgy and
Many diverse ore systems are classified together as iron oxide coppergold (IOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of oreforming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as
Iron Oxide Copper Gold Ore Deposits. Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between % to
Examples of the iron sulphidecopper (gold) deposits are the Mt Isa and Gunpowder deposits, many small occurrences in the Eastern Fold Belt (Mt Isa Inlier), the El Soldado deposit, and others. The iron oxide copper (gold) deposits and the iron sulphide copper (gold) deposits display a more distant association with near coeval granites of quot;Iquot; or quot;Aquot; type affinities.
Iron oxide coppergold (IOCG) deposits are a research focus of the current ore deposit geology, and have attracted much attention among the worldwide geologists and exploration experts due to their shallow depth, a wide variety of mineral species and large scale. This paper presents a review of the present IOCG deposits research, which includes the
#0183;#32;Iron oxide coppergold (IOCG) deposits contain economic or anomalous gold, and the gold distribution is important both for its economic significance and ore genesis. However, the gold distribution in IOCG deposits and its controlling factors remain unclear.
Iron oxide coppergold (IOCG) deposits are a research focus of the current ore deposit geology, and have attracted much attention among the worldwide geologists and exploration experts due to
Many diverse ore systems are classified together as iron oxide coppergold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of oreforming fluid, metals, or other ore components. Such deposits have (1) Cu, with or without Au, as economic metals; (2) hydrothermal ore styles and
Learn how Exploring for IOCG Iron Oxide Copper Gold Ore Deposits using formation models and geophysics before drill will save you a fortune.
Iron oxide copper gold ore deposits are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between % and 5% copper, with gold contents ranging from to gt;3
Iron oxide coppergold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most igneous rocks, and (5) no clear spatial associations
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.
