The Caraj s Mineral Province CMP stands out on the world stage for its giant high-grade iron ore deposits 65 Fe discovered in 1967 and mined since 1985 at Serra Norte mines later in the Serra Leste and Serra Sul mines.
Apr 09 2021 The Caraj s Mining Province is located in the State of Par Brazil and belongs to the Amazon region. It has notably abundant mineral resources including active mines of iron Fe nickel Ni copper Cu and manganese Mn Vasquez amp Rosa-Costa 2008.
The Caraj s Mineral Province is located 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 Caraj s and Rio Maria terrains.

Jan 06 2020 A huge manganese ore reserve discovered in the Guizhou province in early 2017 is believed to contain an estimated 203 million tonnes of manganese ore with a total value predicted to be more than 10bn. The manganese ore resources in China are mainly distributed across Guangxi Hunan and Guizhou provinces.
Jan 01 2012 Each metallogenic epoch introduced its own deposit types of which porphyry copper and related skarn followed by sediment-hosted stratiform copper and then iron oxide copper-gold IOCG are globally preeminent. Nonetheless genesis of the copper provinces remains somewhat enigmatic and a topic of ongoing debate.

iron manganese and arsenic in groundwater in the study area were analyzed by statistical methods and spatial analysis. The results show that the source of Fe and Mn in the groundwater of the platform is the iron and manganese nodules in the clay layer while in the river valley plain it originates from the soil and the whole aquifer.

First iron and then manganese were oxidized and precipitated when anoxic iron- and manganese-rich deep ocean water mixed with oxygen-bearing shallow ocean water on shelf platforms that rimmed the first large cratons. Oxygenation of the deep ocean water in the Late Paleoproterozoic 2.0 to 1.8 Ga meant the demise of manganese and iron formations.

the most important Brazilian mineral province. Following the iron de-posit discoveries in the 60s other metalliferous deposits have been identied including manganese alumina nickel tin gold platinum group elements and copper. The region is marked by mountainous ter-rains characterized by hills and plateaus surrounded by southern and
was relatively small 14-20 at this phase is also characterised by high iron 4.5-6.5 at and calcium 8-10 at content. Iron was also detected in the other phases except calcite. The XRD analysis of sintered samples showed that in hydrogen the manganese oxides in the ore were reduced to MnO and iron oxides to metallic iron Figure 1.
Aug 25 2017 The province was subject to several phases of tectonism and metamorphism being tectonically stabilized at 2.26 to 2.01 Ga. From Venezuela to the Amazon Valley the greenstones are remarkable for their mineral deposits of gold iron and manganese plus tantalum and tin in pegmatites.

Mineralogical analyses and major and trace element geochemistry combined with iron and sulfur isotopes were applied to banded iron formations BIFs and pyrite-bearing sandstones from the Caraj s mineral province Brazil. The BIFs belong to the 2.7 Ga old Gr o Par Group and show a rather simple mineralogy hematite and quartz or cryptocrystalline silica. Their REEY patterns suggest .
