• Resumen

  • Texture analyses were done in mylonitic amphibolites from the Careón ophiolite (Órdenes Complex, NW Iberia). Experiments were carried out using time-of-flight (TOF) neutron diffraction and electron back scattered diffraction (EBSD) techniques to determine crystallographic preferred orientation of the principal phases. While both techniques appear to be complimentary, neutron diffraction plus Rietveld data refinement showed better resolution of low-symmetry phases. Results are discussed within the geological context (Gómez Barreiro et al., 2007a) supporting a continuous deformative evolution from the closure of the Rheic Ocean to the Variscan accretion.
