| Abstract | The Itaqueri Formation, in its type-area, comprises rU000xdace;ous deposits of alluvial fans covering the serras of Itaqueri, Sao Pedra, Sao Carlos and Cuscuzeiro, and its origin is related to the evolution of the Japi Planation Surface. A Paleocene-Eocene age is inferred from the age of alkaline rocks emplaced along the Rio Moji-Guacu Lineament which caused hydrothermal silicification coeval with the sedimentation. Deformation tectonics of this unit is characterized by brittle structures, mainly faults and joints, related to movements along the Rio Tiete, Sao Carlos - Leme and Rio Moji-Guacu Lineaments. The stress-field for these faults presents a horizontal NW-oriented σ1, a horizontal NE-oriented σ3, and a vertical σ2, compatible with a WNW to E-W right-lateral strike-slip binary ofprabable neotectonic (Quatemary) age |
