Abstract

The Paranavaí Alloformation (Alto Rio Paraná Allogroup) is a allostratigraphic unit representative of quaternary geological history in the Upstream Rio Paraná Hydrographic Basin. This unit is composed by arenaceous to rudaceous homogeneous colluvial deposits, originated in place or after a restricted transportation, from weathered cretaceous lithostratigraphical units of Bauru Supersequence.The sedimentary records of Upstream Rio Paraná Hydrographic Basin, since at least 1 My ago to present days, would testify important palaeoclimatic changes and/or neotectonic events, that allowed to systematize the Cenozoic geologic-geomorphologic evolutionary phases in the Brazil. However, until now, the deposits of Aloformação Paranavaí in subsurface are unknown, although likely to contain important stratigraphyc records, palaeoclimatic and/or recent tectonics, which could be detected by detailed sedimentologic studies properly dated by the luminescence method. Thus, the project aims to study the sediments of the subsurface Aloformação Paranavaí. (AU)
