"Paulipetro" has drilled about a score of stratigraphic and wildcat wells in the Paraná Basin getting unique informations of the interrelations and distributions of the rock units in its sedimentary filling. This paper presents the new stratigraphic chart demonstrating time-space relationships of the rock units and a revised chrono-stratigraphic classification for the Paleozoic sedimentary section of the Parana Basin. As an initial approach, the proposed chrono-stratigraphic column presents only three units (Serie Campos Gerais, Serie Rio Tiete and Serie Serra do Espigão). However, based on the distinctive geological evolution of the Paraná Basin, it has essentially a regional character. The introduction or a new time-space diagram and simplified chrono-stratigraphic column are justified by the demand of improved stratigraphic correlations for petroleum exploration.
