“…Barbosa and colleagues [37] reported that the Igneous Province of Upper Paranaíba are rich in silicate rocks. Given that the pyroclastic deposits and lavas of this Province also covered large areas of the Mata Corda Group [36] [54], it was reasonable for us to infer that these rocks were, and still are, an important source of silica for the surrounding aquatic environments, as are those of the Areado Group, as indicated by [55]. The rocks of the Igneous Province of the Alto Paranaiba are located between the Paraná and São Francisco Basins, one of the most important watersheds in Brazil (Figure 1).…”

“…O sistema de drenagem do Morfodomínio 3 apresenta uma direção principal SE-NW, que é corroborada pelos estudos de proveniência dos sedimentos hospedeiros dos depósitos de espongilito (Almeida et al, 2009a O Morfodomínio 4 é caracterizado por vales em forma de calha, nos quais estão inseridos os rios Prata e Paracatu, apresentando um padrão meandrante. Trata-se de uma feição geomorfológica fluvial definida como rio underfit (Davis, 1913;2008;Dury, 1964;1965), na qual as drenagens atuais cortam suas planícies fluviais segundo um padrão meandrante.…”

“…Segundo Almeida et al (2009a), a grande similaridade sedimentológica dos depósitos de espongilitos, associados às suas características texturais e mineralógicas, sugere que a provável fonte dos sedimentos que compõe esses depósitos está relacionada ao retrabalhamento dos arenitos do Grupo Areado. Essa afirmação é suportada, ainda, pela direção SE-NW do sistema de drenagens da região associada à ocorrência dos arenitos do Grupo Areado na porção SE da área.…”

“…Gerais -CETEC (1981), Oliveira, Valle and Féboli (2002), CPRM (2003) and Almeida et al (2010), this study area is located on the unconsolidated tertiary-quaternary ferruginous detritus-laterite sediment, formed from the process of transport and deposition mainly from the reworking of the Areado Group, upstream. Almeida (2009) indicates that this stratum is superimposed on the karstic-fissured lithostratigraphy of Bambuí Group.…”
