• Resumen

  • The strain in a orthogneissic body (Lubrín orthogneiss) of the Bédar-Macael Nappe deformed by a large shear zone with a mylonitic fabric associated has been studied. The asymetric pattern in prophyroclast-ó systems, S-C structures and Quartz -C- fabrics indicates a WNW sense of movement (N280-290° E mean orientation of the stretching lineation). Using Fry and Angular Orientation of lines's methods several principal strain ellipse ratios has been measured. The ellipsoids obtained are plotted in the apparent constriction field (Flinn diagram).
