For example, all abstracts in the various PET Petrology sessions are found within the PET section of the abstract volume, and alphabetically by author therein. This is to ease searching for abstracts while sitting within a given theme session. Welcome to Sweden! Welcome to Lund! It is with great excitement and pleasure that we welcome you to Skåne in southern Sweden for the 31st Nordic Geological Winter Meeting! The Geologiska Föreningen is very proud to be able to organize this meeting, which has become a strong tradition in our Nordic countries and, judging by the content of this year’s presentations, continues to provide an important and highly valued venue for presenting research, making connections, and meeting old and new friends. We hope that we all have a fulfilling three days of high-level scientific discussions, The oral talks, held in 6 rooms in parallel sessions, run the entire gamut of the field of geology, although with a very special Scandinavian stamp. We also are glad to welcome into the ‘midst’ of this conference, Lundadagarna, an annual conference held at Lund University specializing in paleontology, historical geology, sedimentology and stratigraphy: this year Lundadagarna is given as part of the NGWM. Sweden’s Geologiska Föreningen and its scientific journal GFF has traditionally focused the many fields of geology into three main areas, and these three are represented in our plenary talks this year. Ólafur Ingólfsson will represent Quaternary and glacial geology with a presentation on Icelan- dic surging glaciers on Wednesday. Uwe Ring, reflecting the area of crystalline bedrock, will present on Thursday on mantle and crustal links. And on Friday, Mary Higby Schweitzer will represent pa- leontology and historical geology with a presentation on her research in preserved dinosaur tissue. We are also excited to be able to give out for the second time, the Nordic Geoscientist Award. Håkon Fossen, structural geologist from Bergen, Norway won the very first award that was given out in Reykjavik at the 30th NGWM in 2012. This year’s winner will be announced at the banquet on Thursday evening. The winner will give a plenary talk at 13:00 on Friday. The organization of a meeting like this requires more than a year of preparation, a task that many people are involved in. We would like to thank the Scientific Programme Committee (SPC) for put- ting together an ambitious program, the conveners for promoting exciting sessions, the plenary lecturers for their contribution, and not least the many sponsors who have made this event possible. We also want to thank Qi Media, Jönköping, and Gert Pettersson, Lund, for building and maintai- ning the 31st NGWM web site, and Creative Support, Göteborg, for producing this abstract volume. We hope that the 31st Nordic Geological Winter Meeting will be fruitful and lead to better and deeper insight into the different fields of geosciences, and stimulate further Nordic collaboration.

Kristoffer Jøtne Walsh Tromsø, Nov. 2013 4 5 Abstract The Skiftesmyr Cu-Zn VMS-deposit is located in the Grong municipality of Northern Trøndelag, Norway. The mineralization has been known since at least 1903, when mention of small workings in the area were first published, and has later been the subject of several exploration projects by different companies, of which MetPro AS is the latest. The Skiftesmyr deposit is a part of the Gjersvik Nappe, which is a part of the Köli Nappe Complex, which in turn is a part of the Upper Allochthon of the Scandinavian Caledonides, and is likely of Mid- Ordovician age.

    Tautra and Hoklingen, Based on a Compilation of 14C-Dates

    NGU BULLETIN, RESEARCH ARTICLE Age of the Younger Dryas ice-marginal substages in Mid-Norway – Tautra and Hoklingen, based on a compilation of 14C-dates Olsen, L.1, Høgaas, F.1 and Sveian, H.1 1 Geological Survey of Norway, P.O. Box 6315 Sluppen, N-7491 Trondheim The ice-marginal Tautra and Hoklingen Substages in the Trøndelag counties, Mid-Norway, have for a long time been referred to as of early and late Younger Dryas (YD) age, respectively. The basis for this is the regional distribution and morphological correlations of the associated moraines and a number of 14C- datings, mainly of marine shells, previously presented in different papers and map-sheets. In this overview article we present a collection of all 14C-dates associated (more or less accurately) with the Tautra and Hoklingen Substages, a number of 49 and 27 respectively. Using all these dates for a first approximation constrain the Tautra Substage to the age interval 13000 – 12500 cal yr BP and the Hoklingen Substage to 12180 –11600 cal yr BP. Improved accuracy of the age intervals can be obtained by further weighing of geology and stratigraphical positions of the dates. Omitting of dates considered to be slightly too old or too young to be strictly representative, have reduced the number of representative dates for Tautra to 24 and for Hoklingen to 22. The corresponding age intervals are now 12900 – 12620 cal yr BP and 12180 – 11760 cal yr BP, for Tautra and Hoklingen respectively. The Vedde Ash Bed, with established age 12066 ± 42 cal yr BP in western Norway, and dated near Trondheim to 12055 ± 35 cal yr BP, is recorded distally to the Tautra Substage and between the Tautra and Hoklingen Substage deposits, but not closer distally than 5 km and not proximally to the latter.

  • Large-Scale Rock Slope Failures in the Eastern Pyrenees: Identifying a Sparse but Significant Population in Paraglacial and Parafluvial Contexts

    Large-Scale Rock Slope Failures in the Eastern Pyrenees: Identifying a Sparse but Significant Population in Paraglacial and Parafluvial Contexts

    Large-scale rock slope failures in the eastern Pyrenees: identifying a sparse but significant population in paraglacial and parafluvial contexts David Jarman1, Marc Calvet2, Jordi Corominas3, Magali Delmas2, Yanni Gunnell4 1 Mountain Landform Research, Scotland 2 University of Perpignan, CNRS UMR 7194, France 3 Universitat Politècnica de Catalunya, Barcelona, Spain 4 University of Lyon, CNRS UMR 5600, France ABSTRACT This first overview of large-scale rock slope failure (RSF) in the Pyrenees addresses the eastern third of the range. Around 30 principal RSFs >0.25 km2 and 20 lesser or uncertain cases have been identified from remote imagery and groundtruthing. Compared with other European mountain ranges, RSF incidence is relatively sparse, displays no obvious regional trend or spatial clustering, and occurs across diverse landscape types, if mainly on metamorphic rocks. A transition is observed from paraglacial RSFs in formerly-glaciated valleys to what are here termed ‘parafluvial’ RSFs, within wholly or mainly fluvial valleys but where slope failure is not directly provoked by or linked to river erosion. RSFs are particularly found in three topographic settings: (i) at cirque and trough-head thresholds (transition zones of elevated instability between cirque and main glaciated trough walls); (ii) near the upper or outer periphery of the ice field, where glacial adaptation of fluvial valleys is incomplete; and (iii) in fluvial valleys beyond glacial limits where incision is locally intense. RSF is absent from the range divide, from within cirques, and from most main valleys. In the montane areas, RSF is strongly associated with vestiges of preglacial summit surfaces, confirming that plateau ridges are less stable than sharpened crests and horns.

    The Håkåneset rockslide, Tinnsjø Stability analysis of a potentially rock slope instability. Inger Lise Sollie Geotechnology Submission date: June 2014 Supervisor: Bjørn Nilsen, IGB Norwegian University of Science and Technology Department of Geology and Mineral Resources Engineering I II ABSTRACT The Håkåneset rockslide is located on the west shore of Lake Tinnsjø (191 m.a.s.l), a fjordlake stretching 32 km with a SSE-NNW orientation in Telemark, southern Norway. The instability extends from 550 m.a.s.l. and down to approximately 300 m depth in the lake, making up a surface area of 0.54 km2 under water and 0.50 km2 on land. The rockslide comprises an anisotropic metavolcanic rock that is strongly fractured. Five discontinuity sets are identified with systematic field mapping supported by structural analysis of terrestrial laser scan (TLS) data. These are interpreted as gravitationally reactivated inherited tectonic structures. At the northern end the instability is limited by a steep south-east dipping joint (JF3 (~133/77)) that is one direction of a conjugate strike slip fault set (JF3, JF2 (~358/65)). Towards the south the limit to the stable bedrock is transitional. A back scarp is defined by a north-east dipping J1 (~074/59) surface that is mapped out at 550 m.a.s.l. Kinematic analysis indicates that planar sliding, wedge sliding and toppling are feasible. However, because the joint sets are steeply dipping these failure mechanisms can only occur for small rock volumes and are limited to steep slope sections only. Large scale rock slope deformation can only be justified by assuming deformation along a combination of several anisotropies.
