Abstract

The AA. used GIS to study correlations between the presence of karstic features, precise lithology and relief to indentify possible controls in non-carbonate rocks within the Santana basin. The results suggest a lithological control on the karstic features with higher frequency of caves, collapsed dolines, sinkholes and resurgences in pure quartzite (Q) and in areas with high relief, but there is no lithological control on solution dolines. Gullies, knickpoints and captured valleys are also not controlled by lithology or relief. The results suggest a fluvial control of gullies and depositional features in valley bottoms caused by headward erosion, after underground captures or knickpoint disruption
