Soils at Imaggeo: Pores in ‘heart-shaped’ pyrite aggregate in clay

Pores in ‘heart-sh, by aped’ pyrite aggregate in clay, by Susanne Hemes. Click to see the original picture at Imaggeo.

The image was taken using a ‘Zeiss – Supra55’ Scanning Electron Microscope at 15,000x magnification and 10kV electron acceleration voltage, as part of my PhD work on the porosity in fine- and coarse-grained Boom Clay samples. The picture shows pores in framboidal pyrite aggregates, embedded in a fine-grained clay matrix. Boom Clay is being considered as a potential host rock material for the deep geological disposal of radioactive waste in Belgium and the Netherlands and therefore the detailed characterization of its pore space is of wider importance.
