“…Clusters 1 and 2 have a similar order of their main ions and show the presence of strontium, magnesium, calcium, and pH is lower than 7. These clusters are related with the Serra Geral aquifer's waters, in conformity with studies [6,31,32].…”

“…In the South region of Brazil, Serra Geral aquifer is present (crystalline aquifer with 102,000 km²), constituted by rocks originated by basaltic spills on the formation of the Guarani aquifer. In some regions, as in the state of Paraná, is known that the two aquifers may exist as an integrated system since their waters have connections by means of the fracture rocks of the crystalline aquifer so as by means of water flows from the portion with higher pressure (Guarani aquifer) to the region of lower pressure (Serra Geral aquifer) [5][6][7].…”

Brazil is a country with different physical and climatic conditions, located in a diverse range of geological structures and abundant in water resources. Among the aquifers present in southern America, the Guarani and Serra Geral aquifer are two of great importance to the population. With the need to improve the quality of groundwater and to present more scientific studies on these groundwater sources, the objective of this study was to use cluster analysis and principal component analysis/factor for hydrogeochemical characterization and groundwater quality and correlate these findings with contaminants from human activities. This study was divided into two steps, hydrogeological characterization, and analysis of some contaminants that cause negative impacts on human health. The study area was a hydrographic basin located within Maringá, Paraná, Brazil. The results demonstrate that the groundwater of this basin has the dominant hydrogeochemical characteristic of calcium bicarbonate type and sodium carbonate type. The hierarchical cluster analysis was effective to the hydrogeological characterization and classified 18 sources in three distinct clusters. It was possible to correlate pollution sources that were contributing to the decline of the quality of this basin. Nitrate and benzene were related to the main pollution originating from the urban area; manganese, chromium, and lead from the old landfill; nickel and copper from electroplating industries; and pesticides atrazine and diuron, were related to the agricultural activities. The present study is of great relevance, because, in addition, to characterize the type of water (hydrogeochemical), it allowed to identifying harmful contaminants to human health in the region by correlating them with their origin.

The Paraná Volcanic Province follows Siberia as the second largest in the continents and offers a unique opportunity to study the hydrothermal relationship between basalt-rhyodacite lavas and buried erg-turned aquifer in an intraplate setting. Injected sand fluidized after basalt sealing and was succeeded by amethyst and agate geode opening and filling. Excellent exposures in the Herveiras cuesta, southern Brazil, allow the comparison of processes over long distances (1500 km) in the volcanic group. Fieldwork and basalt chemistry led to the identification of three hydrothermal processes-amygdales filling (H1), sand injection (H2) and amethyst geodes formation (H3). Sand injection was triggered by high temperature (150 ℃) and seismicity. These low-temperature processes identified in the Herveiras cuesta demonstrate the homogeneity of relationships between the paleoerg, giant aquifer and intraplate volcanic rocks across the volcanic province.

“…Com exceção dos depósitos de Tenente Portela (RS) e Realeza (PR), que estão associados a basaltos da Formação Serra Geral, Cretáceo da Bacia do Paraná (Arena et al 2014), os jazimentos cupríferos do Brasil ocorrem em terrenos precambrianos, conforme pode ser observado na Figura 1. Estes depósitos ainda se distinguem dos demais por apresentarem cobre nativo como concentração primária, associado a crisocola e malaquita como mineras de alteração supergênica.…”
