Plegamiento recumbente en la Serra do Galiñeiro (Pontevedra, NO España)

Abstract

Three main deformation phases (D1, D2 and D3) have been identified in the Serra do Galiñeiro using macro and microstructural analysis. The geometric characterization of those showing macrostructural elements (D2 and D3), has been made with the down-plunge method, for the folds related to each phase. In order to apply this technique, the fold axis orientation has been calculated from the structural data collected. The results of this research prove the existence of recumbent folds in the southern part of the Malpica-Tui Unit, and the presence of a stretching lineation related to the main foliation and the recumbent folds, and clearly oblique to their axes.
