Neue Beobachtungen zur Chronostratigraphie der mittelwisconsinzeitlichen Vergletscherungen und Böden mexikanischer Vulkane

Klaus Heine
The chronostratigraphical position of a mid-Wisconsin moraine of the Nevado de Toluca volcano/Mexico is described and compared with former stratigraphies. The 26,000 — 21,000 yr B.P. soil of the central Mexican highland cannot only be proved at La Malinche volcano but also in the Sierra Nevada de México (Río Frio) and at the Nevado de Toluca volcano by radiocarbon determinations. Both observations confirm the former stratigraphical works of the author.
