Abstract

Computed microtomography (CMT) can be used to provide information regarding spatial distribution of minerals and aspects of porosity and permeability. Synchrotron-based x-ray CMT has several distinct advantages over conventional textural and mineralogical analytical methods in that it is noninvasive and non-destructive. Further, the high intensity, collimated x-ray beam yields analyses with a high spatial resolution. Synchrotron X-ray CMT analyses were carried out on three samples at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France (ID 19 beamline) using an x-ray energy of 30 keV. The CMT analyses thus far have provided a glimpse into the potential uses of synchrotron-based techniques to statistically assess porous geological media, and possibly to image mineral phases of interest. The primary objective of this chapter is to utilize CMT to image pore size and connectivity in 3 dimensions. A secondary objective is to determine the relationship, if any, between potentially reactive silicate minerals and the aforementioned pore space network.
