| description |
The shape-preferred orientation (SPO) is a technique, which allows the study of the fabric of deformed rocks and understanding its dominant deformational style and partitioning. This work presents SPO results and methodological aspects for one hand specimen of rock and a highresolution composed image of an outcrop through digital image processing. The technique involves imaging of three semi-orthogonal oriented sections for digital processing and subsequent implementation in structural software. The image processing consists of digital separation of a phase of interest, i.e. defining the deformational fabric. The processed images are then implemented in the SPO2003® software for acquisition of sectional ellipses and finally implemented in the Ellipsoid2003® software to obtain the characteristic ellipsoid of deformational fabric. For outcrops, due to the difficulty to finding three appropriate sections for photography, it was only obtained a sectional ellipse, characteristic of the rock fabric based on contrasting deformed quartz segregates in mylonitic schists. |

Presentamos estudios de OPF y aspectos metodológicos para secciones pulidas de roca en muestra de mano y afloramiento a través de tratamiento digital de imagen. La técnica consiste en la captura de imágenes de tres cortes de roca semi-ortogonales orientadas para tratamiento digital y posterior implementación en software estructural. El tratamiento de imagen consiste en la separación digital de una fase mineral que defina la fábrica deformacional. Las imágenes tratadas, son implementadas en el software SPO2003® para la obtención de elipses seccionales e implementadas en el software Ellipsoid2003® para la obtención del elipsoide característico de la fábrica deformacional. Para el caso de afloramiento, se presentan resultados para una sección vertical métrica. Se obtiene la elipse representativa de la fábrica bidimensional definida por los segregados milonitizados de cuarzo.application/pdfspaUniversidad Nacional de Colombia Sede Medellin.
