    <description descriptionType="Abstract">&lt;p&gt;Two crystalline rock drill cores from the Grimsel site were scanned with a Nikon XT H 225 - scanner. The samples were prepared (formatted and cast in epoxy) by UJV Rez, Czech Republic. The CT-data were acquired and processed at HZDR-FWOT.&lt;/p&gt;

&lt;p&gt;Sample 1 (GAM_UJV_1C_1) contains a complex system of interconnected fractures.&lt;br&gt;
Sample 2 (GAM_UJV_1C_2) contains one single end-to-end fracture with larger aperture.&lt;/p&gt;

&lt;p&gt;Size of both samples: Diameter 80 mm, length 165 mm.&lt;/p&gt;

&lt;p&gt;Two tomograms were acquired for both samples:&lt;br&gt;
1) Complete drill core as one scan, voxel size ca. 75 &amp;micro;m.&lt;br&gt;
2) HR-tomogram merged from three sections with maximum resolution, voxel size ca. 40 &amp;micro;m.&lt;/p&gt;

&lt;p&gt;The tomograms were stored as 3D-raw files. Data format, acquisition parameters, and processing workflow, are documented in the tomogram header files (nrrd-format (text):&amp;nbsp; see https://teem.sourceforge.net/nrrd/format.html).&lt;br&gt;
This data format is importable into open-source visualization programs as 3D slicer (https://www.slicer.org) or Paraview (https://www.paraview.org). The data processing has been conducted with Avizo (https://www.thermofisher.com/de/de/home/electron-microscopy/products/software-em-3d-vis/avizo-software.html).&lt;/p&gt;
