ABSTRACT Se han sometido muestras de la dolomía de Laspra (una de las rocas utilizadas en la construcción de la Catedral de Oviedo) a ciclos de hielo-deshielo con el fin de estudiar la aplicabilidad de la tomografía axial computerizada de rayos X al estudio de las características texturales de la roca, así como a la evaluación de los daflos producidos; las muestras han sido observadas en superficie por medio de una lupa binocular tras cada ciclo, detectándose la aparición de fisuras en el cuarto ciclo. La tomografía de rayos X (TAC) ha suministrado una información precisa del desarrollo de la fisuración en el interior de las muestras, pudiendo observarse que el mismo está asociado al límite entre dos zonas texturalmente diferentes. Debido al carácter "no destructivo" de la tomografía de rayos X, se comprueba su aplicabilidad al estudio del interior de los materiales rocosos, tanto para la detección de fisuras, como para conocer su distribución y desarrollo en relación a la textura de la roca

    ABSTRACT: Macroscopic textures resulting from different atomic-scale mechanisms for metamorphic crystallization display different degrees of order, clustering, intergrowth and relative isolation of porphyroblasts. Data on the sizes and locations of thousands of crystals in a three-dimensional volume are required to identify reliably the mechanisms governing nucleation and growth of porphyroblasts from these textural features. These data can now be acquired by means of high-resolution computed X-ray tomography. Numerical models that simulate porphyroblast formation governed by either interface-controlled or diffusion-controlled reaction mechanisms indicate that quantitative textural analysis can discriminate between these possibilities. These numerical models also allow a comparison between textures predicted for different crystallization mechanisms and textures measured in natural samples, from which inferences can be drawn concerning the relative importance of these mechanisms in nature. An independent test of the validity of such inferences is possible for porphyroblasts such as garnet that may preserve prograde growth zoning and allow the examination of normalized radius–rate relations.

    ABSTRACT: The medical x‐ray computerized tomography (CT) scanner has proved to be a useful tool for studies of fluid flow in porous media, with particular applications in reservoir engineering and enhanced oil recovery. This paper explains how CT is used to measure the volume fraction of pore space occupied by up to three discrete phases, such as oil, water, and gas. The image processing system, x‐ray transparent high‐pressure flow equipment, choice of fluid dopants, and x‐ray energies are described for scanning of core flood experiments. Examples are given of tertiary miscible carbon dioxide displacements in Berea sandstone.
