Abstract
Se ha estudiado la tensión en un cuerpo ortogneisico (Lubrín orthogneiss) del Bédar-Macael Nappe deformado por una gran zona de cizallamiento con un tejido mylonitic asociado. El patrón asimétrico en los sistemas profiloclastos-a, estructuras SC y telas de cuarzo indica una sensación de movimiento WNW (orientación media N280-290º E de la línea de estiramiento). Usando Fry y la orientación angular de los métodos de las líneas, se han medido las relaciones de elipse de deformación several principal. Los elipsoides obtenidos se trazan en el campo de constricción aparente (diagrama de Flinn)
The strain in an ortognesic body (Lubrin orthogneiss) of the Bédar-Macael Nappe has been studied, and it was deformed by a great shear zone with an associated mylonitic fabric. The asymmetric pattern in the profiloclastic-o systems, SC structures and quartz fabrics point out a sensation of movement WNW (average position N280-290º E from the stretching line). Using Fry and the angular orientation of the line method, the ellipse relations of several main deformations have been measured. The obtained ellipsoids are traced in the apparent construction field (Flinn Diagram).
