Geology in Management Plans: subsidies for environmental zoning of the Intervales State Park (PEI), São Paulo, Brazil.

Abstract

During the development of Management Plan of the Intervales State Park (PEI) and its buffer zone was given special emphasis on Geology due the occurrence of carbonate rocks with karst systems and caves (one of the major tourist attractives of the park) and to contain important mineral resources. The geology study was based on bibliography, geoprocessing, cartographic control of geological units and tectonic structures, geochemistry of carbonate rocks, research of the mineral titles and occurrences and hydrogeological assessment. As results were established aquifer systems and its vulnerability, the regions of greatest potential for development of karst and the analysis of the mineral resources and minning. There is a need for a detail on the karst systems, which was included as a new chapter in the Management Plan. The provided data contributed for environmental zoning once the geological systems studied have high environmental vulnerability particularly against the anthropic impacts on soil and groundwater.
