The Kattendijk Formation (also known as the Kattendijk Sands) is a five-million-year-old marine geological formation with outcrops north of Antwerp, Belgium. The area was named by De Heuter and Laga in 1976. The sands range from medium fine to coarse and contain a large proportion of shell grit.
Geology The clay is of Rupelian age and developed to a depth of approximately beneath a deposit of Neogene sand. The formation has a Miocene epoch aquifer, while the clay level dates to the Pliocene.
