Abstract
Computed tomography (CT) scanning is used increasingly in engineering and earth science studies, but has been developed essentially for medical applications, thus there is a lack of data processing and analytical tools for geoscience studies. We present a simple method to digitally process CT scan images of permafrost cores. A Matlab script was developed which allows volumetric contents of gas, ice, and other inclusions to be determined. In addition to classical cryostratigraphical differences between sediment, ice and gas, CT scanning is used to characterize the cryotexture of cores by using volumetric contents. We demonstrate our methodology using natural permafrost samples from the Klondike area, central Yukon.
