Samples were allocated to Steve Sutton of the Consortium for Advanced Radiation Sources (CARS), University of Chicago, under a NASA research grant. CT is of interest for determining locations and size distributions of clasts, fusion crust thickness, modal abundance of phases, porosity, density, and possibly the distributions of terrestrial weathering products. The ability to determine the locations of clasts non-destructively is valuable, for example, in developing sampling strategies and allocation plans for rare meteorites such as those from the Moon and Mars.
The CT images were obtained by Betsy Dowd at NSLS Beamline X27C in 1995. These 2d images were then combined into a single 3d volume by Mark Rivers, also of CARS. Randy Hudson, Mathematics and Computer Science Division, Argonne National Laboratory, then volume rendered the final view of the 256x256x256-element volume.
