There are some general observations of the behavior of the different sample solutions that deserve to be noted here. Due to the cohesion degree of the core sample not all treatment solutions were capable to completely disintegrate the sample's mass. The most effective reagent to turn the sample solution into homogeneous mud slurry was H2O<sup>2</sup> regardless of its concentration or admixture. The sample aliquots that were treated with water or Na6O18P<sup>6</sup> solution did not completely disintegrate and small chunks of sediment were left still standing in the beaker that required some extra mechanical effort to dissolve better. Finally, beaker 4 which contained simultaneously both H2O<sup>2</sup> and Na6O18P<sup>6</sup> exhibited strong foaming during treatment time.
