About Itabirite
A laminated, metamorphosed oxide-facies iron formation in which (1) the original chert or jasper bands have been recrystallized into megascopically distinguishable grains of quartz and (2) the iron is present as thin layers of hematite, magnetite, or martite (Dorr & Barbosa, 1963). The term was originally applied in Itabira, Brazil, to a high-grade, massive specular-hematite ore (66% iron) associated with a schistose rock composed of granular quartz and scaly hematite ( hematite schist). The term is now widely used outside Brazil for any banded iron formation.
Decomposed varieties are called jacutinga, and laterised varieties Canga.
Decomposed varieties are called jacutinga, and laterised varieties Canga.
