Excursion to the Harz 2021 (Resources and regional geology) © Rebecca Hartmann Tectonics and Resources Teaching eCampus: further information & registrations Information about the study of geosciences at RUB BSc studies Field excercise to endogeneous and exogeneous processes (Module no. 4: Basics of Geosciences) Lecturers: N.N. The field exercise is intended to familiarize students with the basic working methods of geosciences in the field. This includes the use of the geological compass, magnifying glass, rock description and the creation of sketches of outcrops. Students learn to interpret what they observe and draw conclusions about the geological processes that have taken place. The field exercise deals with various topics on exogenous and endogenous processes. For this purpose, outcrops of the Upper Carboniferous along Lake Baldeney and a quarry of the now largely dismantled Kunkskopf volcano in the Eifel are visited over two days. The students then learn how to write short field trip reports. It is recommended that students attend this course in the second BSc semester, as it teaches the basics for field trips in later semesters. Field excercises: methods - Tectonics, Coal and Mining (Module no. 8: Methods of field work) Lecturers: Dr. S. Schuth The field exercise "Tectonics" deals with the investigation and interpretation of stratifications, fissures, folds and faults. Students will learn how to use a geological compass and how to evaluate and interpret the data obtained in a regional geological context. This two-day field exercise visits various outcrops in the Harz Mountains. It is combined in terms of time and topic with the Harz excursion on "Regional Geology and Resources", so that students spend four field days in the Harz (2 days of field methods, 2 days of regional geology and resources) and can make better use of their time in the Harz. The field exercise "Coal and Mining" focuses on the processes of coal formation, the transformation of the Ruhr area through progressive coal mining and technical development as well as the consequences of mining in the Ruhr area. Students are expected to work independently on the processes of coal formation on the basis of outcrops and to create profiles with the help of field investigations in order to determine the expected position of a coal seam on the ground surface. The two-day field exercise visits various outcrops in the Ruhr area as well as the former Nachtigall colliery in Witten. Field excercise Regional Geology (Harz) (Module no. 7: Resources and regional geology) Lecturers: Prof. A. Dziggel, Dr. S. Schuth, Dr. M. Hueck This field exercise deals with the geological development of the Harz Mountains from the Devonian to the Permian. The most important rock types and geological events are presented: Depositional environments of Devonian and Carboniferous sediments and volcanic rocks, Variscan mountain building, intrusion of Brocken granite and basic and ultrabasic rocks, and the transgression of the Zechstein Sea. Note: The field exercise Methods "Tectonics" (see module "Field Exercises: Methods") visits various outcrops in the Harz Mountains. It is combined in terms of time and topic with the Harz excursion on "Regional Geology and Resources", so that students spend four field days in the Harz (2 days of field methods, 2 days of regional geology and resources) and can make better use of their time in the Harz. Geological maps and profiles (Module no. 8: Methods of field work) Lecturer: Dr. S. Schuth The lecture introduces students to the use and interpretation of geological maps. Students learn how to create profiles and develop a three-dimensional geological image from two-dimensional information and derive the temporal development of an area from this. In addition, the use of the geological compass is taught and the evaluation methods of the data obtained with it are presented. Successful completion of a written exam is required prior to participation in Mapping Course 1. Mapping Course 1 (Module no. 8: Methods of field work) Lecturers: Prof. A. Dziggel, Dr. S. Schuth, Dr. M. Hueck In this module, students learn how to map an area geologically and construct geological profiles. This includes determining the position in the field, recognizing and determining the location of layers and faults, displaying the findings on a geological map and recording stratigraphic profiles. Resources and regional geology (Module no. 7: Resources and regional geology) Lecturer: Prof. A. Dziggel This lecture introduces students to the basics of mineral deposits and regional geology. The regional distribution, economic importance and production of raw materials in Germany are explained on the basis of the geological development of Central Europe in different geological eras. The most important ore minerals and structures as well as the use of metallic and non-metallic raw materials are presented. Further information: BSc module handbook.

Bachelor- und Master-Arbeiten Master-Arbeit „Vanadium als Rohstoff – Mineralogie und Vanadiumkonzentrationen in repräsentativen Vorkommen in Kanada“ Master-Arbeit zum Thema „Vanadium as a resource – mineralogy and vanadium concentrations in representative deposits in Canada“ Hintergrund - Das Spurenelement Vanadium (V) ist in industriellen Fertigungsprozessen und Alltagsanwendungen weit verbreitet. So wird es beispielsweise bei der Herstellung von Stahl mit einer besonders hohen Härte und hochfesten Metallstrukturen als Veredler für Stahllegierungen eingesetzt. In der chemischen Industrie dient V als Katalysator zur Herstellung von Schwefelsäure, einem wichtigen Reagenz in zahlreichen chemischen Herstellungsverfahren. Im Alltag wird V in Metallwerkzeugen eingesetzt, um deren Härte zu erhöhen. Vanadium ist auch von besonderer Bedeutung für den Übergang zu grüner Energie als alternativer Speicher für elektrische Energie in Form von V-Redox-Flow-Batterien. Die wichtigsten Exporteure von V-Erzen sind derzeit China, Russland, Südafrika und Brasilien, aber auch andere Länder haben begonnen, ihre Explorationsaktivitäten zu erweitern. Kanada beispielsweise verfügt über eine leistungsfähige Bergbauindustrie und zahlreiche V-Vorkommen, die jedoch derzeit nur in vergleichsweise geringem Umfang abgebaut oder erkundet werden. Aufgrund seiner chemischen Eigenschaften tritt V als Spurenelement in Sedimenten, z. B. in Schwarzschiefern, sedimentär-exhalativen (SEDEX) Lagerstätten, in Magmatiten (z. B. Fe-Ti-V-Magnetite) sowie in Bitumen und Ölsanden in Gehalten von mehreren Promille auf und wird in derartigen Vorkommen z.T. abgebaut. Arbeiten - Im Rahmen der Master-Arbeit sollen mehrere bekannte Vanadium-Vorkommen in Québec und Yukon (Kanada) untersucht und beprobt werden. Hierzu ist eine ca. dreiwöchige Probennahme im Sommer 2023 und 2024 zusammen mit Kooperationspartnern der University of Toronto (Kanada) geplant. Aus den gewonnenen Proben werden an der RUB Dick- und Dünnschliffe erstellt. Nach eingehender mikroskopischer Untersuchung der Schliffe erfolgt eine weitere Untersuchung mittels Mikrosonden-Analytik ebenfalls an der RUB. Ein besonderes Augenmerk soll auf die Bestimmung der mineralogischen Verteilung des Vanadiums in den Proben gelegt werden. Die Analysen hierzu werden im neuen Laser-Ablation-ICP-Massenspektrometrie-Labor der Arbeitsgruppe Tektonik & Rohstoffe durchgeführt. Fragestellungen Welche Unterschiede im Mineralbestand der beprobten Vanadiumvorkommen gibt es? Wie ist die Vanadiumkonzentration und -Verteilung in den Mineralphasen (z.B. auch Zonierungen, V-reiche Einschlüsse)? Wie können die Vanadium-Verteilung in und zwischen den Mineralphasen und mögliche Konzentrationsunterschiede zwischen den Probenlokalitäten erklärt werden? Welche Ursachen kommen für die Vanadiumanreicherung in den Vorkommen in Frage? Anforderungen - Für die Bearbeitung der Master-Arbeit werden die Fähigkeit zur Arbeit im Gelände bei jedem Wetter, Interesse an der Arbeit im neuen LA-ICP-MS-Labor der Arbeitsgruppe Tektonik und Rohstoffe, und gute Englischkenntnisse erwartet. Außerdem sind Kenntnisse zu den Themen Rohstoffe und Geochemie und Mikroskopie-Erfahrung hilfreich.
