X-ray CT Scans of three chips of the Murchison chrondrite meteorite (USNM 5487; 'chip 3-5' first in CT series, followed by 'chip 1', and finally 'chip 3-1') for Romy Hanna of The University of Texas at Austin. Specimens scanned by Matthew Colbert on 13 May 2016. Voxel Size X and Y and Z = 9.99 μm. Total slices = 1804. Please acknowledge The University of Texas High-Resolution X-ray CT Facility (UTCT), NASA grant NNX13AO64H, and Dr. Romy Hanna when using this data.
