Petrologische und Geochemische Untersuchungen an ultramafischen und mafischen Gesteinen der Shackleton Range, Ost-Antarktis Zeugen des Zusammenschlusses Gondwanas und letzte Relikte eines einstigen Ozeans? Der Naturwissenschaftlichen Fakultät/ Dem Fachbereich Geographie und Geowissenschaften der Friedrich-Alexander-Universität Erlangen-Nürnberg zur Erlangung des Doktorgrades Dr. rer. Nat. vorgelegt von Tanja Romer aus Illertissen i Als Dissertation genehmigt von der Naturwissenschaftlichen Fakultät/ vom Fachbereich Geographie und Geowissenschaften der Friedrich-Alexander-Universität Erlangen-Nürnberg Tag der mündlichen Prüfung: 01.06.2017 Vorsitzende/r des Promotionsorgans: Prof. Dr. Georg Kreimer Gutachter/in: Prof. Dr. Esther Schmädicke Prof. Dr. Reiner Klemd ii Zusammenfassung Im östlichen Teil der Antarktis liegt die Shackleton Range. Es handelt sich hierbei um ein Kollisionsorogen, das nach heutigen Erkenntnissen der panafrikanischen Orogenese zugeordnet wird. Hinweise darauf finden sich im nördlichen Bereich (z.B. Haskard Highlands) der Shackleton Range. Hier treten granatführende, ultramafische Gesteine als Linsen, eingeschlossen in hochgradig metamorphen Gneisen auf. Die Linsen setzen sich hauptsächlich aus granat- und/oder spinell-führenden Pyroxeniten und untergeordnet auch Peridotiten zusammen. Die nähere Umgebung der Linsen wird vor allem durch Amphibolite dominiert. Die Pyroxenite enthalten teilweise eine Verwachsung von Granat und Olivin und sind damit ein eindeutiger Indikator für eine eklogitfazielle Metamorphose in diesem Bereich. Weiterhin zeugen sie als ultramafische Gesteine von einer möglichen Suturzone. In dieser Forschungsarbeit konnte mittels Mikrosondenanalytik an Granat, Ortho- und Klinopyroxen, Spinell, Olivin und Amphibol für die ultramafischen Gesteine ein Teil des im Uhrzeigersinn verlaufenden P-T-Pfads rekonstruiert werden. Thermobarometrische Berechnungen ergaben maximale Metamorphosetemperaturen von 800 bis 850 °C. Die maximal erreichten Drücke dürften zwischen 20 bis 23 kbar gelegen haben. -

1 Transcript of a Recording of Jeremy Light, Interviewed at Peterhouse
Transcript of a recording of Jeremy Light, interviewed at Peterhouse College on 15 September 2007 by Chris Eldon Lee. Jeremy Light, BAS Archive AD6/24/1/29, transcribed by Barry Heywood, 8 November 2015. Light: Jeremy Light. I was born 30th January 1943 in Salcombe, South Devon. [00:00:22] Lee: What were you doing before you came to BAS or Fids? Light: I was a student at Aberdeen University, studying Zoology at first, then Honours in Botany. [00:00:38] Lee: What drew you into going to the Antarctic? Light: Two things. There was an old Fid called Ian McLeod [G.K.McLeod - Transcriber?] who went down to the Antarctic many times. I remember him saying that it was the only way he could escape from women. And then I was very lucky to be able to go to an evening slide show given by Dr Macklin who was on Shackleton’s last voyage. No! not the last voyage – the famous boat voyage one. And that was really inspiring to me. [00:01:19] Lee: You didn’t want to get away from women particularly? Light: No! No I didn’t want to get away from my woman. [Lee laughs] We have known each other from practically birth. [00:01:34] Lee: So how did you go about fulfilling your wish, your dream? Light: Well, when I had finished my honours, I applied to BAS, but in fact, I had started on an honours project…I did some work on the high corrie lochans in the Cairngorms and found aquatic mosses there…quite a find…and so it seemed tailor-made for me when there was a job to study lakes on Signy Island. -

This paper uses remote-sensing, structural glaciological and sedimento- logical data to evaluate the evolution of the c. 25000 km2 George VI Ice Shelf, SW Antarctic Peninsula. The ice shelf occu- pies a north–south-trending tectonic rift between Alexander Island and Palmer Land, and is nourished mainly by ice streams from the latter region. -

ABSTRACT The carbonate clasts from the Mount Wegener Formation provide sedimentological, diagenetic and palaeonto- logical evidences of the destruction and resedimentation of a hidden/unknown Cambrian carbonate shallow-water record at the Coats Land region of Antarctica. This incomplete mosaic could play a key role in comparisons and biostratigraphic correlations between the Cambrian record of the Transantarctic Mountains, Ellsworth-Whitmore block and Antarctic Peninsula at the Antarctica continent. Moreover, it represents a key record in future palaeobio- geographic reconstructions of South Gondwana based on archaeocyathan assemblages.
