Subject: Seminar abstract Date: Thu, 14 Sep 2000 12:06:01 +0200 From: Walter Kutschera To: Ina Vostrel Ina, hier ist das Abstract von Susan Ivy-Ochs: Surface exposure dating of boulders on moraines with 10Be, 26Al and 36Cl: the Last Glacial Maximum to the Preboreal Susan Ivy-Ochs, Institut fuer Teilchenphysik, ETH Zuerich Surface exposure dating with cosmogenic nuclides has been used with success on rock surfaces exposed from several thousand years up to ten million years. I will focus on Last Glacial Maximum and younger samples. The overriding goal is to try to fit glacial advances into the world-wide temporal framework of warm and cold periods. Results from various sites will be presented, focus will be on the Alps. Details about the method with respect to field considerations, sampling and sample preparation will also be briefly discussed. ___________________________________________________________ Walter Kutschera Institut fuer Isotopenforschung und Kernphysik der Universitaet Wien VERA-Laboratorium, Waehringer Strasse 17 A-1090 Wien/Austria Tel. +43-1-4277-51700 Fax: +43-1-4277-9517 email: Walter.Kutschera@univie.ac.at ___________________________________________________________
