· An exception is the Carajás mineral Province in the Amazon Craton, where voluminous IFs from the Neoarchean Carajás Formation host giant highgrade iron ore deposits associated with the recurrent circulation of fluids of magmatic origin. Giant ore deposits of this metal are also present in the Paleoproterozoic Imataca granulite facies Complex in the Transamazon/Guianas Province of the .
Carajas is Brazil's largest iron ore mine. The volcanic sequence has been weathered to a depth of between 100m and 150m. intends to deploy 37 autonomous haul trucks at the Carajas mine by 2024. Image courtesy of Ltd. For Q2 2008 Carajas produced million tonnes of iron ore, an increase over the previous corresponding period.
· This geologically blessed loion is rich in gold, copper, iron and manganese deposits of exceptional quality. The manganese found in Carajás has a purity of 80%, thanks to the process of time ...
Iron and manganese oxides occur as vug fillings in palladian gold and are associated with native palladium and Pdoxygenated compounds. The nearsurface bonanza palladian gold mineralization is part of a larger, deeply weathered, hydrother mal system which, in deepest drill holes (>300 m), has a relict sulfide assemblage with a variable degree of overprint by iron oxides, sericite, and ...

INTRODUCTION. The Carajás province ( Ma) is the oldest part of the Amazon craton and it is loed in the southeastern Pará state, north of Brazil (Santos et al. 2000, Santos 2003).It comprises one of the largest mineral provinces of the world (Carajás Mineral Province), hosting worldclass deposits of iron, copper, and gold (DOCEGEO 1988, Grainger et al. 2008).
Abstract The Carajás Province presents several volcanosedimentary sequences that comprise the Itacaiúnas Supergroup. The rocks represent bimodal volcanism, and clastic and chemical sedimentation in relatively unstable basins subject to recurrent structural events with subsidence and volcanism. The Grão Pará Group represents one of these sequences with mafic volcanic rocks that enclose ...
The Carajás Mineral Province is loed at the sotheast of the Amazon Craton, northern Brazil and is the second largest one in the world in respect to iron, gold, manganese and copper deposits (Grainger et al., 2008 apud Fabre, et al., 2011). Althoff (2000) divided this province into Carajás and Rio Maria terrains. The Archean rocks
The Carajás Mineral Province (CMP) is loed on the southeastern margin of the Amazonian Craton, in northern Brazil. It is the largest producer of highgrade iron ore and a major world supplier of copper, nickel, manganese and gold. This article presents the CMP as a product of oblique rift evolution ( Ga) controlled by the Canaã and Cinzento strike slip system.
