Trabajos de Geología, Universidad de Oviedo, 29 : 278-283 (2010) From ductile to brittle deformation – the structural development and strain variations along a crustal-scale shear zone in SW Finland T. TORVELA1* AND C. EHLERS1 1Åbo Akademi University, Department of geology and mineralogy, Tuomiokirkontori 1, 20500 Turku, Finland. *e-mail: [email protected] Abstract: This study demonstrates the impact of variations in overall crustal rheology on crustal strength in relatively high P-T conditions at mid- to lower mid-crustal levels. In a crustal-scale shear zone, along-strike variations in the rheological competence result in large-scale deformation partition- ing and differences in the deformation style and strain distribution. Keywords: shear zone, deformation, strain partitioning, terrane boundary, Finland, Palaeoproterozoic. The structural behaviour of the crustal-scale Sottunga- several orogenic periods from the Archaean to the Jurmo shear zone (SJSZ) in SW Finland is described.

High Paleoproterozoic radiogenic heat production is assumed. The material viscosity is temperature-dependent following the Arrhenius law. The experiments use two sets of rheological parameters for the crust: dry (granite/felsic granulite/mafic granulite) and wet (granite/diorite/mafic granulite). The results of the modeling are compared to seismic reflection sections and surface geological observations from the Paleoproterozoic Svecofennian orogen. Numerical modelling is performed with Ellipsis, a particle-in-cell finite element code suitable for 2D thermo-mechanical modelling of lithospheric deformation. It uses Lagrangian particles for tracking material interfaces and histories, which allow recording of material P-T-t paths. Plateau-models are based on a 480 km long section of 65 km-thick three-layer plateau crust. In the plateau margin-models, a transition from 65 km thick plateau to 40 km thick foreland is imposed in the middle of the model. -

Box 1047 Blindern, NO-0316 Oslo, Norway. Correspondence to: Jean-Baptiste Koehl ([email protected]) 10 Abstract. The SW Barents Sea margin experienced a pulse of extensional deformation in the Middle-Late Devonian through the Carboniferous, after the Caledonian Orogeny terminated. These events marked the initial stages of formation of major offshore basins such as the Hammerfest and Nordkapp basins. We mapped and analyzed three major fault complexes, i) the Måsøy Fault 15 Complex, ii) the Rolvsøya fault, iii) the Troms-Finnmark Fault Complex. We discuss the formation of the Måsøy Fault Complex as a possible extensional splay of an overall NE-SW trending, NW- dipping, basement-seated Caledonian shear zone, the Sørøya-Ingøya shear zone, which was partly inverted during the collapse of the Caledonides and accommodated top-to-the-NW normal displacement in Mid/Late Devonian-Carboniferous times. The Troms-Finnmark Fault Complex 20 displays a zigzag-shaped pattern of NNE-SSW and ENE-WSW trending extensional faults before it terminates to the north as a WNW-ESE trending, NE-dipping normal fault that separates the southwesternmost Nordkapp basin in the northeast from the Finnmark Platform west and the Gjesvær Low in the southwest. -

Dating of late- to post-tectonic Sveconorwegian granitic intrusions from South Norway by the SIMS U-Pb method on zircons and by internal Pb-Pb isochrons on rock-forming minerals indicates a major event of granitic magmatism all across southern Norway in the period 950 to 920 Ma. This magmatic event included emplacement of mantle- derived magma into the source region of granitic magmas in the lower crust east of the Mandal-Ustaoset shear zone, and formation of hybrid magmas containing crustal and mantle-derived components. -

NORDEA BANK PRESENTS A GUIDE TO COPENHAGEN GUIDE TO COPENHAGEN ANNUAL REPORT OF OJSC NORDEA BANK FOR 2013 GUIDE TO COPENHAGEN Annual Report 2013 OJSC Nordea Bank Dear frienDs, I am delighted to present the Annual Report of Nordea Bank Russia. It is the second one in our series of travel guides to capitals of the Nordic and Baltic countries which are Nordea’s home markets. This time — introducing Copenhagen. On my first visit to Copenhagen — well before 2007 when our Russian bank became part of Nordea and we started going on frequent business trips to the Nordics — I was amazed by the city’s unique lifestyle. I would call it eco-friendly: people are lively and active, but no one is in a rush, there are many large modern buildings, but the streets are cozy and intimate, and the whole city is simple, straightforward, nice and comfortable. This guide will not only lead you through Copenhagen’s landmarks, museums, parks, restaurants and clubs, but will also let you feel the free spirit and nature of this beautiful city. Denmark has been one of Nordea’s home markets for over two centuries. Sparekassen for Kjøbenhavn og Omegn, opened in 1820, is among the oldest banks Nordea stems from. It boasts of having served Hans Christian Andersen, the first name you think of when you say Denmark, and we are sure that’s a fact, not a legend. Besides Denmark, Nordea, the largest financial services group in Northern Europe, operates in Sweden, Norway, Finland, the Baltics and Russia. 2013 proved to be a difficult year for both global and European economy, its financial and banking sectors. -
Copenhagen's Famous Mermaid: Den Lille Havfrue, the Little Mermaid
Copenhagen’s Famous Mermaid: Den lille havfrue, The Little Mermaid The Little Mermaid was made famous by a fairy tale written by Hans Christian Andersen, Denmark’s famous author. It was a tale about a young mermaid who was willing to give up her life in the ocean and her life as a mermaid to gain a human soul. “The tale was actually made to scare children into good behavior.” ‐ quietlunch.com ‐ hca.gilead.org Copenhagen’s famous statue is that of the Little Mermaid, however there are rumors that the original is not what is displayed by the City of Copenhagen. Why you ask. Well, the original was sculpted by Edvard Erkisen who was commissioned to do the statue in 1909. It was unveiled on August 23, 1913, a gift from the Danish brewer Carl Jacobsen from Carlsberg Brewery. Four years later the 385‐pound bronze statue was presented to the City of Copenhagen and placed in the harbor area. Since her appearance, she has been vandalized and scandalized. It is believed that the original is with the Eriksen family. Vandalism has included decapitation three times, an arm being attacked with a hacksaw, someone even used an explosive to blow her off her pedestal and throwing paint on her five times. The scandal came from none other than Facebook who banned her from its online publication due to nudity guidelines. ‐ bbc.com ‐VisitDenmark The mermaid’s history was also plagued with problems from the beginning. According to VisitDenmark, “The Little Mermaid was meant to be modelled after contemporary ballerina Ellen Price, but as she refused to model nude, the Mermaid was in fact modelled after Edvard Eriksen’s wife, Eline.” “The statue was sculpted as a twin‐tailed mermaid, although the H.C. -

Paleozoic Petroleum Systems on the NCS – Fake, Fiction Or Reality?
Extended Abstract Paleozoic Petroleum Systems on the NCS – Fake, Fiction or Reality? What is presently Known & What Implications May such Source Rock Systems Have – Today - in terms of Exploration? SWOT Prof. Dr. Dag A. Karlsen, Univ of Oslo The Jurassic source rock systems continue to form the backbone for exploration on the Norwegian Continental Shelf NCS), with hitherto only 5 oil accumulations proven to be from Cretaceous source rocks, and with Triassic source rock contributions mainly occurring in the Barents Sea. At the “other end of the stratigraphy” we have the Paleozoic rocks. Paleozoic source rocks were recognized early in Scandinavia, e.g. the Alum shale, which we today know to have generated petroleum during the Caledonian Orogeny (Foreland Basin), bitumen found now in odd-ball places in Sweden e.g. at Østerplane and at the Silje Crater Lake and also in Norway. It took until 1995 until we could, via geochemical analytical work on migrated bitumen from the Helgeland Basin (6609/11-1), with some certainty point to migrated oil from a possible Devonian source (affinity to Beatrice & the Orkney shales). Also around 1995, we could suggest bitumen from the 7120/2-1, later realized as one of the wells in the Alta Discovery v.200m dolomite Ørn/Falk Fm) to be of a non-Mesozoic origin, and possibly from a Paleozoic source, and geologist at RWE-Dea and later Lundin started to consider the Paleozoic reservoir systems at Loppa High and also the possibility of Triassic and Permian source rocks as a play model. Why did it take the scientific and exploration environment in Norway so long time to consider source rock systems outside the Jurassic as important? Part of the reason is the great success of the Jurassic Plays on the NCS. -

(Asha Group) of Ediacaran-Middle Cambrian(?) age along with the results obtained from the Early Devonian Takaty Fm. are presented. The age of the Asha Group is traditionally labeled as Upper Vendian in the Russian stratigraphic chart that overlaps with the Ediacaran in the International stratigraphic chart. The dZr whose ages fall within the age-interval of (500-750 Ma) are common in the Basu and Kukkarauk Fm. These ages are typical for crystalline complexes in the Pre- Uralides-Timanides orogen. The identification of zircons with this age range agrees with commonly adopted interpretations for the depositional origin of the Asha Group as a molasse resulting from the erosion of that orogenic belt. Based on the estimates of the youngest ages of dZr along with the tentative identification of inarticulate brachiopods in the Kukkarauk Fm., it appears that the upper part of the Asha Group may extend into the Middle Cambrian.
