| description | <p>Until now, reliable chronological classifications based on numerical
ages for many Pleistocene fluvial deposits in the Alpine Foreland were rare.
In this study, new numeric data (ESR, OSL, <span class="inline-formula"><sup>14</sup>C</span>) from
Middle and Upper (Late) Pleistocene <i>Hochterrassen</i>
(high terraces) and
<i>Übergangsterrassen</i> (transitional terraces) in
the Bavarian Alpine Foreland are presented. The dating results imply that
the <i>Hochterrassen</i> gravel sensu
stricto were deposited during the penultimate glacial (MIS 6,
Rissian), and that underlying older gravel accumulation are predominantly of
penultimate interglacial (MIS 7, Riss–Riss interglacial) age. In some areas
of the <i>Hochterrassen</i> in the Danube valley south
of Regensburg (interglacial <i>Hartinger Schichten</i>,
Harting layers), and in some areas of the <i>Rainer Hochterrasse</i> (basal gravel unit I),
<i>Hochterrassen</i> gravels are underlain by much older
interglacial gravel deposits. These interglacial basal gravel deposits
illustrate that the downcutting of these valleys far away from areas of
Pleistocene foreland glaciations happened predominantly during
warm-temperate interglacial or late-glacial periods. One last interglacial
(MIS 5e, Riss–Würm interglacial)
<i>Hochterrasse</i> is morphologically preserved in the
Isar valley. This <i>Jüngere Moosburger Hochterrasse</i> is composed of the
<i>Fagotienschotter</i> (Fagotia gravel, named after the
gastropod <i>Fagotia acicularis</i>). The next younger
terraces are the Early to Middle Würmian (MIS 5d to MIS 3?)
<i>Übergangsterrassen</i> (transitional terraces),
whereas the younger one of the two <i>Übergangsterrassen</i>
was formed most probably during the Middle Würmian (MIS 3).</p> |
