“…The waters of the region have a positive calcite residual alkalinity (RA calcite ) (alkalinity . Ca 2+ in millimoles of charge mmol c ; Droubi et al 1980) and therefore develop a sodic alkaline pathway under the influence of evaporation (Barbiero et al 2002(Barbiero et al , 2004. Such geochemical evolution is frequent in continental arid or semiarid environments and has been described in all the continents ).…”

“…At the local level, water and solute flows are complex (Hamilton et al, 1998) and depend on many classical factors affecting water flows in wetlands, such as the configuration of levees, slight variations in the topography, resistance to flow related to vegetation, local rainfall intensity and tributary inputs (Girard et al, 2010). In addition, in some parts of the Pantanal characterized by an absence of apparent drainage networks, the sub-surface flows are controlled by systems of thresholds between lakes (Barbiero et al, 2007. According to Hamilton et al (1997) and on annual basis, the inflow of water in the Pantanal is nearly equivalent to the amount drained.…”

“…Essa região tem sido objeto de recentes pesquisas, das quais se destacam aquelas voltadas aos processos pedológicos que acompanham a mineralização das águas (Rezende Filho, 2006;Furquim, 2007;Barbiero, et al, 2008). Os estudos de solos realizados entre lagoas contíguas mostraram que os regimes hídricos das lagoas são comandados por horizontes verdes argilosos, mais ou menos cimentados, cujos complexos sortivos, saturados em sódio (Na/T>25%), limitam fortemente a permeabilidade.…”

“…A presença desses horizontes vinha sendo associada ao ambiente alcalino do entorno das lagoas salinas (Sakamoto, 1997;Rezende Filho, 2006;Furquim, 2007;Furquim et al, 2004;2009). Contudo, eles também foram encontrados em áreas não ocupadas por salinas, em pequenas depressões preenchidas com águas apenas durante as enchentes.…”
