Kattendijk Formation (Belgium)

The Kattendijk Formation (also known as the Kattendijk Sands) is a five-million-year-old marine geological formation with outcrops north of Antwerp, Belgium.[2] The area was named by De Heuter and Laga in 1976.[3] The sands range from medium fine to coarse and contain a large proportion of shell grit.[4]

Geology

[edit]

The clay is of Rupelian age and developed to a depth of approximately 70 m (230 ft) beneath a deposit of Neogene sand.[3] The formation has a Miocene epoch aquifer, while the clay level dates to the Pliocene.[5]
