Extent of Alpine glaciation (blue: edge of the ice sheet in the Mindel and Riss glacial periods)

The Mindel glaciation (German: Mindel-Kaltzeit, also Mindel-Glazial, Mindel-Komplex or, colloquially, Mindel-Eiszeit) is the third youngest glacial stage in the Alps. Its name was coined by Albrecht Penck and Eduard Brückner, who named it after the Swabian river, the Mindel. The Mindel glacial occurred in the Middle Pleistocene; it was preceded by the Haslach-Mindel interglacial (often regarded as part of Günz) and succeeded by the Mindel-Riss interglacial (Holstein interglacial).

The Mindel glaciation is commonly correlated to the Elster glaciation of northern Europe. The more precise timing is controversial since Mindel is commonly correlated to two different marine isotope stages, MIS 12[1] (478–424 thousand years ago[2]) and MIS 10[3] (374–337 thousand years ago[2]). This ambiguity is much related to the correlation problem described in more detail in the article 'Elster glaciation'.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
