9 Opalinus Clay samples, both from the argillaceous and from the sandy facies, scanned with the microfocus CT-scanner (µCT) Nikon XT H 225 at HZDR FWOT, including drill cores and cuttings (preparation remnants).

The voxel size (ca. resolution) is between 10 µm and 100 µm.

All tomograms were stored as 3D-blocks with unsigned 16-bit integers of uncalibrated gray levels. The voxel size and dimensions are given in the file name.
