ANÁLISE DE FÁCIES DA FORMAÇÃO CORUMBATAÍ (GRUPO PASSA DOIS - BACIA DO PARANÁ, NEOPERMIANO), COM VISTA AO EMPREGO NA INDÚSTRIA DE REVESTIMENTO CERÂMICO

Abstract

TITULO DO ARTIGO EM INGLÊS. The mud rocks from Corumbataí Formation, Neopermian unity of Paraná Basin, are at the moment, the principal font of raw material for floor tiles industries in Brazil. In this paper we are applied the lithofacies concept, mineralogical and chemical composition data and ceramic characteristics for define exploration places. It was identify five lithofacies (Massive, Laminated, Intercalated I, Intercalated II and Alterated) all they grouped in two associations (sandy siltstone and argillaceous silstone). The data was plotted in map 1:50,000 scale. This method permits get a best control on raw material, consequently better quality and chipper. It was important the statistical method application (Tendency Surface Analysis) for define the probable areas for future exploration.
