Banded Iron Formation, BIF Brazil
Banded iron formations are distinctive units of sedimentary rock that are predominantly of Precambrian age.
Banded iron formations are typically comprised of repeated thin layers of black to silver iron oxides. They are often red in color and are either magnetite (Fe3O4) or hematite (Fe2O3). They alternate with bands of iron-poor shales and cherts.
Banded irons formations can be among the oldest known rock formations and are found in multiple location around the world including: South Africa, Australia, Brazil, Canada, Russia, India, the Ukraine, and the United States.
This specimen of Banded Iron is from the Itabira Iron Quadrangle, Brazil. This locale is mined for iron, gold, and palladium with associated unique precious-metal-bearing mineral assemblage.
Specimen size: 27mm H X 28mm W X 12mm D
Ships with tag, display case, Certificate of Authenticity and information.
This specimen would make a great addition to a geological collection that also includes other rare geological location specimens and unique banded iron collections.
