...) relatively high U/Pb and (2) low Th/U values, when compared to galena in the major carbonate-hosted Zn ± Pb deposits (Vazante, Morro Agudo, Ambrosia, Fagundes) in the Vazante Group. These results support the hypothesis that Zn-rich layers and veins in mineralized carbonaceous phyllites could be linked...

Verde Formation, which consists of a thick succession of dominantly gray to pink algal-laminated dolomite, gray to green slates, sericite phyllite, and dolomite breccias that host the Zn–(Pb) deposits (i.e., Vazante, Morro Agudo, Fagundes e Ambrósia; e.g., Monteiro et al., 2007 ; Slezak et al., 2014...

... (FV). Carboxymethylcellulose (CMC) is an example of a polymer that has the ability to improve viscosity and decrease FVs (Fagundes et al ., 2018 ). The clay minerals kaolinite, smectite, palygorskite (Plg) and sepiolite are among the world's most important and useful industrial minerals (Murray...

... ( Fig. 7 ). Low-Ge concentrations in tennantite are also confirmed by LA-ICP-MS elemental maps ( Fig. 8 ). Tennantite thus is a poor Ge-carrier in Fule. EPMA studies of galena from the Fagundes and Ambrósia deposits, Brazil, found an uncommon abundance of Ge (up to 8470 μg/g), exceeding concentrations...

.... The reason for the growth is solely the development of large kaolin deposits in the Amazon Basin that account for 90% of Brazil’s production. In 2005 there are just two companies involved in the production and sales of kaolin from the Amazon Basin, namely Imerys (RCC – Rio Capim Caulim) and Caemi...

These synrift shales became the primary source rock for the main hydrocarbon systems present in all the South Atlantic basins. As the separation between South America and Africa...

Furthermore, some species and subspecies from WD were lumped together retrospectively after a reanalysis, as they likely represented various morphologies of the same species. The four floras used in these analyses were deposited during the Late Pennsylvanian to middle Permian...

...–Early Cretaceous, a relative sea-level fall caused a subaerial exposure and karstification of the carbonate platform ( Wenke et al. 2011 ). A very significant sedimentary influx from the continental margin also takes place during the Early Cretaceous, depositing thick sand layers forming the Tan-Tan...

The small lateral coverage of these outcrops suggests that they were generated by floods, which may have deposited and trapped live mollusks and dead shells in depressed areas of the ancient floodplain of the TPR, as is presently observed in the modern TPR floodplains.
