The Tiglian, also referred to as the Tegelen, is a temperate complex stage in the glacial history of Northern Europe.
The stage was introduced by Zagwijn in 1957 based on geological formations in Tegelen in southern Netherlands.
[1] The Praetiglian and Tiglian are today regarded as corresponding to the Biber stage in the glacial history of the Alps and to the Gelasian (2.6-1.8 million years ago) in the global division of the Quaternary period.
[2] Thus, there have probably been about 20 glacial cycles of varying intensity during Praetiglian and Tiglian.
The dominant trigger is believed to be the 41 000 year Milankovitch cycles of axial tilt.
