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. -

(paper cover) FOEEWOBD The "Lexicon of geologic names of the United States" by M. Grace Wilmarth, published in 1938 and reprinted in 1951 and 1957, met a long standing need and continuing demand for a compilation of geologic names. Plans made for future compilations as new names and revisions appeared were interrupted during the years of World War II. In 1952 a sustained effort was begun toward review of geo logic publications necessary to furnish a background for preparation of a new edition. After the review was brought up to date in 1956, the present compilation was prepared in order to furnish to the geo logic profession, as quickly as possible, some of the essential data concerning the new names that have appeared since 1935. -

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.
