“…Such differences for porosity estimations occur due to the length of pore diameter and the scanned voxel size. Because Itacolumite has a large pore diameter (>100

μ

m) within the quartz skeleton (Suzuki et al., 2011), XCT can resolve the pores, including the unconnected pores. Hence, the XCT estimation is slightly higher than the He pycnometry estimation.…”

X-ray computed tomography (XCT) has become a popular method in fracture characterization of rocks. After Wellington & Vinegar (1987) first utilized XCT for petrophysical studies, it became a popular method in analyzing and visualizing the internal structure of rocks in the early 1990's (e.g., Johns et al., 1993;Orsi et al., 1994;Vinegar et al., 1991). Later with the use of it to characterize the porosity of fault zones (Antonellini et al., 1994) and strain localization in shear bands (Desrues et al., 1996) in deformed rocks, its implications in geophysical applications were realized. However, these were not powerful enough in both penetration and resolution to obtain high resolution images of high-density formations. This led the subsequent studies of Otani et al. (2000) to perform their experiments in a more developed and powerful industrial type XCT scanner, which was able to reconstruct the internal structure of soil in a nondestructive manner. They further showed that the structure of soil samples can be investigated quantitatively based
