Análise de bacia aplicada à prospecção de água subterrânea no planalto ocidental paulista, SP

A Bacia Sedimentar do Paraná tem posição de destaque, em nível nacional, com relação a sua potencialidade para recursos hídricos, por abrigar várias unidades produtoras, com ênfase no Sistema Aqüífero Guarani (SAG). O presente estudo representa uma aplicação do método de análise de bacias para caracterização dos sistemas aqüíferos Botucatu, Serra Geral, Caiuá e Bauru, todos de idade mesozóica, no Planalto Ocidental Paulista. Com base na integração de informações provenientes de poços tubulares profundos, mapas estruturais, mapas e seções estratigráficas, foi possível apontar áreas favoráveis a execução de projetos para exploração de água subterrânea, de acordo com as características geológicas de cada área identificada nesta província geomorfológica do território paulista. Palavras-chave: Bacia Sedimentar do Paraná; Sistema Aqüífero Guarani; Planalto Ocidental Paulista; Exploração de Água Subterrânea.

Sedimentação na bacia do Pantanal Mato-Grossense, Centro-Oeste do Brasil

The Pantanal is a Quaternary sedimentary basin located at the left margin of the Upper Paraguay River, west-central Brazil. Basin infilling was mainly by siliciclastic sediments and the stratigraphic succession exhibits an overall finingupward pattern. The depositional system tract is composed by a large meandering fluvial plain and several marginal alluvial fans, being the Taquari megafan the most striking feature. The present landscape is a complex tropical wetland, with geomorphic features derived from the present conditions and other inherited from successive Pleistocene and Holocene climates. During the Pleistocene, the sedimentary environment was dominated by braided alluvial fans, the original geometry of which is preserved as relict forms, permitting remarkable patterns of distributary paleochannels to be easily recognized in satellite images. Eolian processes were active in some abandoned lobes, contemporaneously with sedimentation in active fan lobes. Closed ponds bordered by lunette sand dunes, originally salt pans produced by eolian deflation, are relict eolian landforms in the Pantanal landscape. Eolian processes were probably more effective at the glacial maximum. Landscape has been changing in the Pantanal area since the end of the Pleistocene in adaptation to a more humid and warmer environment prevailing during Holocene. Initiation of the modern wetland has occurred during the Pleistocene / Holocene transition, with the change to a more humid climate and the individualization of lacustrine systems. The modern Pantanal wetland is a vast expanse of poorly drained lowlands that experiences annual flooding from summer to fall months. Although climatic fluctuations have occurred during all the Holocene, the alluvial fans have remained active depositional systems and lobes were formed by progradation and abandonment. Abandoned lobes were subjected... (Complete abstract click electronic address below)

Mapeamento geológico-geomorfológico na região de Quirinópolis-GO

Geological and geomorphological mapping is an important tool for the characterization of physical environment, thus enabling the planning and use of areas more efficiently. This work represents a geological- geomorphologic mapping on the scale of 1:20.000 in the rural area of Quirinópolis – GO town, where outcrop rocks of Paraná Sedimentary Basin, specifically the Bauru Group. Through the methodology of analysis of integrated elements of the physical environment, it was possible to delineate geological- geomorphological five units, which were characterized as lithology, topography, soil conditions, and operating processes, and the development of weathering profiles bring of great importance for planning of land use as occupation thus avoiding further degradation of the physical environment

Caracterização mineralógica, petrológica e química da sulfetação nos reef's da mina Canavieiras, Jacobina, Bahia

In the Serra de Jacobina, localized in the North Central portion of the state of Bahia, occours the Jacobina Group. It’s a sedimentary basin and the gold deposit is stocked on the basal portion, which consist on quartzites intercalated with oligomítico metaconglomerates of Serra do Córrego Formation. There are controversies about the origin of the gold mineralization, but the currently most accepted hypothesis corresponds to a paleoplacer deposit with subsequent ore remobilization and concentration by hydrothermal process. The sulphidation is one of the main results of hydrothermal process, which was more detail characterized, besides identifying if there was more than one sulfides phase generation and its relationship with gold mineralization. The analyzes were performed from the main reef's (metaconglomerates mineralized levels) of Mine Canavieiras: Maneira, Holandez, Liberino, Piritoso, MU and LU. Chemical analyzes semi-quantitative were developed with EDS in MEV and also petrographics analyses. The main sulfide is pyrite, followed by chalcopyrite. Six groups of pyrite were classified according with chemical composition, however they show similarities in their habit and occurrence. Were identified four types of chlorite, labeled A, B, C, D. Gold occurs in free form, associate to pyrites, to Fe-Ti-Muscovite, to chlorite type B and to microfractures with iron hydroxide. Gold presents three different compositions: pure, with Ag or associated with U-Zr. The results of chemical analysis showed that the hydrothermal process have as their main source, ultramafic rocks present in the Jacobina Basin
