SUB-SAMPLING UNCONSOLIDATED SEDIMENTS: A SOLUTION FOR THE PREPARATION OF UNDISTRUBED THIN-SECTIONS FROM CLAY-RICH SEDIMENTS

Abstract

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.
