Multiscale, multimedia and multi-element geochemical mapping of the State of Paraná, Brazil

OTAVIO AUGUSTO BONI LICHT

Abstract


The State of Paraná was the first Brazilian state to perform systematic geochemical surveys on a regional scale, complemented by some more detailed ones, focusing the town of Umuarama and its capital Curitiba as well. In these surveys, stream water samples were collected, together with stream sediments and soil samples, multi-element analyses have been applied with total and/or partial digestion. The results obtained allowed the elaboration of geochemical maps to visualize the spatial distribution of the elements in the territory of Paraná, to establish associations of groups of elements indicating natural environment characteristics and the changes imposed by the human activities as well. The multipurpose applications of this geochemical mapping program contribute to geology knowledge, mineral exploration, environmental diagnostics and identification of areas of risk to human health.
