The Paraná Basin in Brazil is of vital importance and because of a large groundwater reservoir and the high exploitation of this resource by the population a structural and hydrogeochemical knowledge is needed. Objectives: 1) Analyze studies that address the structural, hydrogeological and hydrochemical characterization of aquifers in the Paraná Basin; 2) Highlight the main techniques used in the respective studies and the scientific development arising from the use of these techniques for a better hydrochemical and structural understanding of the Paraná Basin. Methodology: Tracing lineaments from satellite image and field work are the main techniques used for structural characterization. For hydrochemical analyses, factorial methods physical-chemical analyses are used. Results: the most common chemical types of groundwater that circulate in the sedimentary and volcanic units of the Paraná Basin, which include the Pirambóia, Irati, Rio Bonito, Botucatu and Serra Geral formations are calciumbicarbonates, calcium-magnesian bicarbonates, calcium-sodium bicarbonates and sodium-sulphate-chloride bicarbonates. Sodium-sulfated waters are not found in the Serra Geral Formation, except when they come from the sedimentary units. Sodium and sulfate are not expected ions in basalt weathering, and therefore a greater understanding is needed on structural communication by means of faults that occur between the Serra Geral Aquifer System (SGAS) and the mesozoic and permian sedimentary aquifers and aquitards that contribute for unexpected ions in the SGAS. Conclusion: The Paraná Basin is a reason for interest in geological studies in Brazil because of its link to several areas of interest in geosciences, which include hydrochemistry, stratigraphy, paleontology and hydrogeology.

<p>This reasearch discusses the necessary tasks to carry out the hydrogeological characterization of the sands, sandstones, and gravels of the Baixo Alentejo coast. Currently, this characterization has done in detail only in the areas where these formations constitute hydro-stratigraphic units of the aquifer systems of Sines and the Alvalade Basin. In addition to system hydrogeological characterization of the system, the volume of water used for irrigation in the study area was estimated, with the aim of characterizing its inter-annual evolution between 2000 and 2018 and intra-annual for the year 2018. To do so, remote sensing and satellite image processing methods were used (LANDSAT 5 and 8 and MODIS). A synthesis of the hydrogeological characterization is presented in an area of 195.8 km<sup>2</sup>, divided into two aquifer sectors, one located north of the Mira River with 94.12 km<sup>2</sup> and the other south with 101.75 km<sup>2</sup>. The first stage of the work consisted of the analysis of the studied aquifers recharge based on precipitation and the analysis of piezometry data in order to define the conceptual model of hydraulic functioning of the system. The available data were obtained from fieldwork and from the LIFE-Charcos Project (LIFE12NAT / PT / 997). In parallel, an analysis of land use and occupation performed, with emphasis on the identification of irrigation areas. Finally, the volume of water used in agriculture irrigation was determined using the method of estimating the consumptive use of water in irrigation at a local scale, based on the determination of evapotranspiration values, using the algorithm SEBAL, precipitation, and  irrigation efficiency. The results obtained were validated, with high precision, through the comparison with the irrigation volumes known during 2018, and the calibration of the monthly sequential water balance model at ground level.</p><p>Key words: aquifer system of sands, sandstones and gravels of the Baixo Alentejo coast; hydrogeology; Irrigation; Remote Sensing.</p>

Updated data sets on terrestrial heat flow and thermal springs have been employed in outlining the nature of deep-seated geothermal resources of the Parana basin. A 1o x1o grid system was adopted for data processing and in determinations of vertical distributions of excess temperatures. The results obtained have led to an improved understanding of the occurrence of high temperature geothermal resources and allowed estimates of associated resource base. It has been possible to identify more than 20 crustal blocks where the resource base per unit area, referred to the accessible depth limit of 6 km, are in the range of 2x1011 to 9x1011 Joules. There are indications pointing to occurrence of medium temperature geothermal resources at depths of 4 to 6 km in several sectors of the central and western parts of the basin. The area extent of such blocks has dimensions of several tens of kilometers. Most high temperature resources occur within the well-known sectors of fault-controlled magmatic activity associated with the eruption of Serra Geral flood basalts. In addition, isolated pockets of high enthalpy geothermal resources are found to be present along the northwestern border. The results have also allowed better assessments of low temperature resources of the Guarani aquifer system, which span over large areas of southern Brazil, western Uruguay and northern Argentina.

ABSTRACT. Recent research projects on the Guarani Aquifer System (GAS-granular), Paraná Basin, Brazil, have been evaluating the tectonic control and its hydrogeological potential, flow patterns, chemical properties and environmental protection aspects.One of this projects is the present research that has investigated a structured area in central State of Paraná of about 23,000 km2, delimited by coordinates 24◦00’S and 25◦00’S, 51◦00’W and 53◦00’W. The study involves Geographic Information System (GIS) integration of aeromagnetic, geological and structural characterization of lineaments based on Digital Elevation Model (DEM) and Landsat images, hydrogeological and hydrochemical data. Basaltic flows and diabase dikes (NW-SE) of the Serra Geral Formation (Lower Cretaceous) predominate in the studied area. These rocks correspond to the overlying Serra Geral Aquifer System (SGAS-fractured). The purpose of the study is to investigate the structural control on both flow and chemism of SGAS groundwater and also to identify fractures that might represent hydraulic connectivity zones to the underlying GAS. Processing and interpretation of aeromagnetic data using various techniques, useful for enhancing shallow sources, and integration with further remote sensing and geological data, allowed to outline the regional structural framework, which is characterized by a mosaic of tectonic blocks delimited by NW-SE (diabase dykes) and NE-SW (Paraná Basin basement) structures. This magnetic-structural framework was compared with the spatial distribution of hydrogeological and hydrochemical parameters. The integrated interpretations made it possible to recognize the structural control on hydrogeology and hydrochemistry of the SGAS and SAG. The results, presented in a georeferenced map, show the main zones of confinement and/or connection of SGAS and GAS. Keywords: Guarani Aquifer System, Serra Geral Aquifer System, Paran´a Basin, hydraulic connection, aeromagnetometry.  RESUMO. Projetos recentes de pesquisa no Sistema Aquífero Guarani (SAG-granular), Bacia do Paraná, Brasil, têm avaliado o controle tectônico e seu potencial hidrogeológico, padrões de fluxo, propriedades químicas e aspectos de proteção ambiental. Um destes projetos é a presente pesquisa, a qual investigou uma área estruturada na região central do Estado do Paraná, delimitada pelas coordenadas 24◦00’S e 25◦00’S, 51◦00’W e 53◦00’W, com aproximadamente 23.000 km2. O estudo envolve integrações em Sistema de Informações Geográficas (SIG) de dados aeromagnéticos, geológicos, estruturais Modelo Digital de Elevação (MDE) e imagens Landsat, hidrogeológicos e hidroquímicos. Lavas basálticas e diques de diabásio (NW-SE) da Formação Serra Geral (Cretáceo Inferior) predominam na área estudada. Estas rochas correspondem ao Sistema Aquífero Serra Geral (SASG-fraturado), sobrejacente. O objetivo do estudo ´e investigar o controle estrutural do fluxo e do quimismo das águas subterrâneas do SASG e identificar também fraturas que possam representar zonas de conexão hidráulica com o SAG subjacente. Processamentos e interpretações de dados aeromagnéticos, a partir de várias técnicas, e a integração com dados de outros sensores remotos e geológicos permitiram a composição de um arcabouço estrutural regional, o qual é caracterizado por um mosaico de blocos tectônicos limitados por estruturas NW-SE (diques de diabásio) e NE-SW (embasamento da Bacia do Paraná). Este novo arcabouço magnético-estrutural foi comparado com a distribuição espacial dos parâmetros hidrogeológicos e hidroquímicos. A interpretação integrada permitiu reconhecer o controle estrutural da hidrogeologia/hidroquímica dos SASG e SAG. Os resultados, apresentados em um mapa georreferenciado, mostram as principais zonas de confinamento e/ou conexão dos SASG e SAG. Palavras-chave: Sistema Aquífero Guarani, Sistema Aquífero Serra Geral, Bacia do Paraná, conexão hidráulica, aeromagnetometria.
