Quickton
With nonswelling are marine , sandy, highly water-bearing clays called that occur in Europe, particularly in the Scandinavian coast. These clays, also known as Quick Clay in Canada, were deposited in coastal seawater with high electrolyte concentrations during the Ice Age. After the land was raised and the table salt was washed out, the water-rich structure is now unstable. Even slight ground vibrations are enough to make them slide even on a slight slope. This thixotropic state (cf. soil liquefaction ) is the same phenomenon as quick earth and quicksand .
