RESUMO

The Campos Gerais region, Paraná, Brazil, holds unique geological, geomorphological e paleontological sets, which are target of numerous works and scientific researcher. This research present a geological and paleontological route using the outcrops occurring along existing roads in the municipalities of Castro and Tibagi, Parana State, Brazil. This roadmap is proposed as a tool to aid teaching and scientific support for fieldworks (classes or applied basic research) developed by teachers and researchers. Fieldwork carried out aimed to the regional recognition and description of stratigraphic sections of the surface, according to the geological context of the Castro and Paraná basins. For each outcrop were built columnar sections showing the following items: 1) lithological description, 2) sedimentary structures and 3) fossil content occurring. All outcrops were correlated with stratigraphic frameworks pre-existing. A total of 20 raised and described outcrops then organized in the form of stopping points along the road PR- 151, PR-340, BR-153 and secondary roads. Stratigraphically the roadmap begins in the volcanic and volcaniclastic rocks Ordovician of Castro Basin. Then cover the glacial rocks of Neo-Ordovician from Iapó Formation and the fluvial-marine rocks Siluro- Devonian from Formation Furnas, and pelitic rocks of the Devonian from Ponta Grossa Formation, ending with the glaciogenic rocks Neo-Carboniferous from Itararé Group (belonging to the Paraná Basin). This roadmap allows the monitoring of succession lithological, stratigraphic, sedimentological and paleobiological in the interval Lower Ordovician and Upper Carboniferous in the Campos Gerais region of Paraná, facilitating public access to new target areas of outcrops and providing a history of research and discoveries each point..
