Drainage Headboards of the Rio Quatorze Base – Serra Geral Formation (Southwest of Paraná): space distribution, morphological properties and structural control

The article introduces results about the space distribution, morphological properties and structural control in drainage headboards of the Rio Quartoze base, Serra General Formation – Southwest of Paraná. The space distribution was sent by geomorphological domain and revealed that the headboards are in their majority (76,32%) on the top flattened surface. It characterized the kind of the drainage axis and these features form, defined by the circularity index. It verifies that the drainage headboards are circular and shallow features. It verifies that the most headboards (61,05%) is controlled by family orientation fractures comparison of the area versus drainage axis orientation of these features and the headboards alignmts orientation.
