Abstract
The lithologies of this area belongs to the Aucthocthonous of CIZ (Central Iberian Zone). They are characterized, in Paleozoic, by the presence of psammopelits and quartzites (Ordovician, Tremadocian-Arenigian). At West outcrop chiastolite schistes with some iron oxides levels and garnet andalusite nodular schistes that probably represent the Valongo's Formation (Lanvirnian-Landeilian). At East outcrop the Slate Graywacke Complex. The intrusive rocks are represented by the Bouça do Frade Granite (medium grain, two micas and porphyroid). We can see also outcrops of pegmatitic granitics dykes, sometimes mineralized, and quartz veins of metamorphic segregation or, occasionally, typically hydrothermal.
Metamorphic's analysis evidence the isogrades obliteration of hercynian plutonic metamorphic final episode to the Barrovian earliest episode, on the South sectors, which contrast with the coexistence of these two episodes in Carreço. So, we put the problem of the proximity of this sector to the alocthonous structures, be responsible by a possible tectonic control in the occurrence of this association, episodic, Barrovian.
Tectonically, we can verified that in the beginning of D1 occurs a transpressive regimen with sinistral component, having as result folding with axial planes of sub-upright to steeply inclined and fold axes plunging of sub-flattened to moderately inclined, sometimes with undulant fold axes; the axial plane S1 surface, sometimes, transecting folds; by the presence of important sinistral shear corridor having as result a sinistral domino structure. The stretching lineation according to the kinematic axis "b", but, the end of D1 attend to the passage to a tangential deformation regimen towards East making a stretching lineation according to the kinematic axis "a" and sheath folds. These structures are compatible with the most important movements of the South sector of the Iberian-Armorican Arc.
D2 is characterized by the passage of a pure shear regimen, that originated essentially conjugate strike-slip faults, to a tangential deformation regimen towards W. This last, is decisive in the occurrence of Bouça do Frade pluton's laminar extravasing and, therefore, by the appearance of inverse faults/thrusts; by folds moderately inclined and folds with axial planes with dip minor than 30; by fracture cleavage.
D3 is defined for a transpressive regimen and his occurrence is showed by open folds, linked to large shear zones. In the D3 appears, rarely, a crenulation lineation; we can also observe that the strechting lineation is following kinematic b-axis.
