Short description
Compact fragment from the Aguas Zarcas meteorite
Full description
We scanned the AZ fragment at the University of Chicago’s PaleoCT Lab, on a GE v|tome|x S model micro-CT scanner using a 240 kV microfocus tube. The fragments were mounted in a 15 ml tube and scanned at a spatial resolution (or voxel size) of 17.028 μm. An 80 kV voltage and 220 μA current were used with an image acquisition time of 500 ms per frame. Three frames were captured and averaged for each position to reduce noise and a 0.2 mm Cu filter was used to reduce beam hardening. The total scan time for the tube of specimens was one hour and fifty minutes.
