Enrolment in a relevant PhD programme. General background in structural geology, sedimentology, volcanology, geodynamics or geophysics. Previous geological field experience is advantageous.
This course addresses the diverse geological history of the Arctic region, including both onshore and offshore regions from Paleozoic to recent times. It will focus on the interplay of plate tectonics and volcanism (including, arc, rifting and plume-related) and explore some of the outstanding region-by-region case studies/questions within the Arctic research community. Based in the gateway to the Arctic, Svalbard, the course will be complemented by field excursions examining the well exposed outcrops and specifically the igneous rocks emplaced over large parts of the Svalbard archipelago.
The course will present the circum-Arctic region in a 4D perspective: the present day structure of this region from surface to deep mantle and how it evolved since the Paleozoic. Students will get an overview of the large-scale kinematics and geodynamics of the Arctic region in space and time. They will learn how to combine onshore and offshore data to uncover the present day tectonic structure of the region and use it, together with other knowledge, for plate tectonic reconstructions. The students will learn about causes and manifestation of volcanism in the circum-Arctic region. The course includes field trips to observe present day preservation of past Arctic magmatism.
Upon completing the course, the students will:
- understand the physical, chemical and structural characteristics of volcanic provinces
- be able to understand plate tectonics principles
- be aware of the links between surface and deep mantle, methods and models using seismology and satellite data
- understand the causal connections between tectonic evolution and episodic bursts of volcanism, as well as the impacts volcanism can have on the global climate
Upon completing the course, the students should:
- know how to identify first-order tectonic provinces from geophysical and geological data
- be able to make a first order interpretation of geophysical, geochemical and geological data connected to magmatic provinces
- be able to make plate tectonic reconstructions using modern software
- be able to interpret mantle tomography models and integrate them in large-scale tectonic interpretation
- be able to identify and characterize igneous rocks in the field
- be able to discuss how igneous plumbing systems may affect subsurface fluid migration
Upon completing the course, the students will:
- gain first-hand experience of actively working both individually and in small groups
- learn how to effectively and safely undertake fieldwork in Arctic conditions
- improve the presentation skills by presenting their work to their peers and creatively tackling the set problems
- communicate their research findings through an article-style report
- gain leadership skills through mentoring fellow students
The course extends over ca. 5 weeks including complusory safety training, and is run in combination with AG-351.
- Pre-course assignment on selected topics and relevant literature that students will present to their peers following arrival at UNIS.
- Overview lectures and exercises at UNIS prior to fieldwork.
- Up to 5 days of fieldwork at relevant localities, mostly as day trips from Longyearbyen.
- Group work at UNIS to work up both pre-existing, provided and freshly acquired data into a research-based project.
- Presentation to the rest of the group.
- Written report summarizing main results in a geology-style article form, to be delivered 1 week after the course ends.

The Arctic Tectonics and Volcanism course was developed and funded by the NOR-R-AM project (https://norramarctic.wordpress.com/). The Centre for Earth Evolution & Dynamics at the University of Oslo was in particular instrumental in establishing this course, and many researchers from CEED contributed as guest lecturers on the course, including Grace Shephard, Carmen Gaina and Morgan Jones.
