“…In Figure 7b, distal tourmalines plot in field 7 reflecting high CaO content. Boron isotope compositions of tourmaline (Garda et al 2009) in Ribeira belt tourmalinites previously studied by Beljavskis et al (2005), showed δ 11 B = −7.51 to −14.58‰. This evidences chemical and isotopic differences from the Ibaré tourmalinite (Figs 7a, b, 8b).…”

“…Chemistry of tourmalinite from seafloor volcano-exhalative activity (Beljavskis et al 2005) shows that distal tourmalines plot into field 6 and proximal tourmalines overlap fields 2, 4 and 5 (Fig. 7a).…”

“…Exhalative activity was responsible for the genesis of both tourmaline-bearing rocks and iron mineralisation. When metamorphosed, these protoliths produced tourmalinites and the metamorphic product of Algoma-type iron formation, both enriched with syngenetic gold mineralisation (Juliani 1993;Garda et al 2003Garda et al , 2005Garda et al , 2009Beljavskis et al 2003Beljavskis et al , 2005. Within this group, lowangle epigenetic shear zone-related gold mineralisation also occurs due to remobilisations of syngenetic gold (Martin et al 1998).…”

“…Geneticamente vinculados aos paleo-sistemas hidrotermais e à atividade exalativa associada também estão presentes BIFs, turmalinitos, granada anfibolitos, metapelitos ferro-manganesíferos, metapelitos ricos em sulfeto, assim como os produtos metamórficos de zonas carbonatizadas, potassificadas e silicificadas (JULIANI 1993;PÉ-REZ-AGUILAR 1996, 2001PÉREZ-AGUILAR et al 2005, 2007, 2011GARDA et al 2003GARDA et al , 2009BELJAVSKIS et al 2005).…”
