Abstract

The Furnas Formation (Silurian to Devonian of the Paraná Basin) consists of medium to coarse sandstones cemented by kaolinite, which reduces its porosity and makes the rock more resistant. The findings indicate that the great features of subterranean erosion are the result of kaolinite dissolution, which intensifies along structural directions, in a region of scarped relief and steep hydraulic gradient. As a consequence, the Furnas Formation displays landforms that are characteristic of a both structural and karstic aquifer
