Sub-sampling unconsolidated sediments: A solution for the preparation of undistrubed thin-sections from clay‐rich sediments

  • Pierre Francus
  • Celese A. Cosby


Using the principles of electro‐osmosis, a sub‐sampling technique for clay-rich sediments is introduced that produces undisturbed thin‐sections from sediment cores. The fragile sample remains in the same disposable box throughout the process, preventing collapse of its structure during sub‐sampling, manipulation and impregnation, as well as other potential problems.
