Saalian supercycle, Mindel/Riss interglacial and Milankovitch's dating

Classic subdivisions are aligned with the glacial/interglacial cycles of marine isotope stage stratigraphies by proposed higher order units called supercycles (SC), bracketed by superterminations (ST). The Saalian supercycle (SC2) includes glacial cycles C, D and E composed of marine isotope stages MIS 6, 7, 8, 9, 10 and 11. The units MIS 7 to MIS 11 correspond to the Great (Gross) Interglacial, estimated from the early geologic considerations to be about 240 millennia long [Penck and Brückner, 1909. Die Alpen im Eiszeitalter, vols. 1-3. Christian-Herman Tauchnitz, Leipzig] and determined from astronomic computations to last 235 millennia [Milankovitch, 1941. Kanon der Erdbestrahlung und seine Anwendung auf das Eiszeitenproblem. Académie Royale Serbe Editions Speciales Section des Sciences Mathématiques et Naturelles, Tome CXXXIII. Stamparija Mihaila Curcica, Beograd, 633pp.). The current high precision radiometric dating fully confirms the accuracy of Milankovitch's determination and the pivotal role of orbital mechanisms in Pleistocene climate change.
