Short summary
We compare images of drillcore from the Alpine Fault in New Zealand that were collected using X-ray computed tomography (CT) and neutron tomography (NT). Both techniques provide 3-D images of the core's internal structure, which would not be possible through visual analysis alone. We find that CT scans are more beneficial, as they can image a wider range of rock types, and this scanning technique is more practical. Nevertheless, NT provides complementary scans over limited intervals of core.
