The Kattendijk Formation (also known as the Kattendijk Sands) is a five million years old marine geological formation north of Antwerp, Belgium. including the north-western parts of the Campine region. The area was named by De Heuter and Laga in 1976.[1] The sands range from medium fine to coarse and contain a large proportion of shell grit.[2][3]
The clay of the Rupelian era developed to a depth of approximately 70 m (230 ft) beneath a deposit of Neogene sand.[1] The formation has a Miocene Era aquifer, while the clay level dates to the Pliocene.[4]
A Pliocene species of auk (Alca stewarti) was found in 2000.[5] A small oceanic dolphin, Pliodelphis, is also known from the formation.[6]
