Miguel Burnier/Dom Bosco Complex: encompasses the mines located in Miguel Burnier, as well as the Dom Bosco mines.The iron ore Miguel Burnier is located in the Quadrilátero Ferrífero (QF), a large gold, iron, aluminum and manganese metallogenetic district covering approximately 7,000 km² in the southern portion of the São Francisco Craton.The Quadrilátero Ferrífero consists of Archaean terrains (Rio das Velhas Supergroup) overlain by Proterozoic platform sediments (Minas and Espinhaço Supergroups). The current setting of the Quadrilátero Ferrífero results from two deformational events. The first represents an extensional event of Paleoproterozoic age (2100-1700 My) forming granitic-gneissic domes with syncline cores overlying the strata of the Rio das Velhas and Minas Supergroups. The second is a compressional event associated with the closure of the Africa/Brazil proto-ocean (650-500 My) located east of the QF. A west-oriented folding belt developed during this event.Miguel Burnier: The Miguel Burnier Complex is located in the southwestern portion of the QF, Serra do Dom Bosco. Itabirites and rocks of the Gandarela and Cauê Formations and rocks of the Piracicaba Group (Minas Supergroup) outcrop therein. The Serra Dom Bosco area is regionally characterized as a syncline, known as Dom Bosco Syncline. The typologies have been classified according to information collected during field visits, from internal reports, drill cores, thin plates, etc.Dom Bosco: The Dom Bosco Mine is also located in the southwestern portion of the QF, Serra do Dom Bosco. Itabirites and rocks of the Cauê Formation and Piracicaba Group (Minas Supergroup) outcrop therein.
