|Title:||Neopaleozoic Striated Surfaces In The Granitic Basement And Clast Pavement Remains Of Salto, Sp [superfícies Estriadas No Embasamento Granítico E Vestígio De Pavimento De Clastos Neopaleozóicos Na Região De Salto, Sp]|

|Abstract:||Near Guaraú Ceramic, localized southwest of Salto city in the State of São Paulo, two granite outcrops, distant some tens of meters from each other, display Neopaleozoic striated surfaces. These surfaces are in contact with diamictites from the Itararé Subgroup. The striae correspond to sub parallel grooves with millimetric spacing and depth, oriented about N48E and dipping 12° to 42° towards SE. Observed features and association with diamictites indicate an origin by glacial abrasion due to ice movement from southeast towards northwest. About 1.8 km east of Salto, unconsolidated material containing flat-iron-shaped and striated clasts was found on top of granite outcrops, interpreted as clast pavement remains.|
