Abstract
To visualize the microstructure in rocks, micro focus X ray CT images that can get three-dimensional data simultaneously with high resolution of 10 micron have been introduced. We obtained multi planar reconstruction images in intact Berea sandstone and Shirahama sandstone. In the intact rocks, pore structures and grain boundaries are distinguished well. Furthermore, existence of the crushed grains arrangements and fracture band is confirmed definitely in the compressed Berea sandstone under confining pressure of 12 MPa. Micro focus X ray CT is rather effective in visualizing the microstructures in rocks.
