"A footprint doesn't look like a boot"- Visualising tephra in 3D using X-ray CT
Poster created in 2015 for Swansea University College of Science Away Day event to highlight the advantages of imaging tephra (volcanic ash) grains in 3D over conventional 2D optical analysis.
***correction of the start of the first paragraph:
"First developed by Hounsfield (1973 for use in medicine, x-ray computed tomography (XRCT) is now used in a wide range of applications including those in geoscience. It was first used by Renter (1989) to study sedimentary rocks." ***
