The Seiland Igneous Province, Northern Norway : age, provenance, and tectonic significanceRoberts, Richard James 27 June 2008 (has links)
The Seiland Igneous Province, of which 5400 km2 is exposed, is hosted within a
discrete terrane within the northernmost part of the Caledonian orogenic belt. The
Province consists of numerous mafic and ultramafic plutons emplaced into a
sedimentary succession indicative of a continental setting. Accompanying this mafic
magmatism is a significant volume of intermediate monzonitic and dioritic rock
(10% of the total exposed igneous rock), as well as numerous nepheline syenite and
carbonatitic intrusions.
This study reports ID-TIMS U-Pb analyses on magmatic zircons from a range of
intrusions, which indicate that the bulk of the Seiland magmatism took place between
560 Ma and 570 Ma, whereas previous studies had produced a range of ages between
420 Ma and 830 Ma. The data indicate that only one magmatic episode is represented
in the rocks of the Seiland Igneous Province, invalidating previous models involving
multiple rifting events over a period of 300 m.y.
Detailed geochemical investigation of several plutons from an evolved high alkali
suite of gabbroic intrusions in the Seiland Igneous Province has shown that these
plutons are generally enriched in trace elements compared to layered intrusions from
other areas across the globe, but that geochemically the gabbros are relatively
homogenous. The rocks yield εHf and εNd values for the gabbroic rocks ranging from
+8 to -6 and from +4 to -4, respectively, indicative of the contamination of mantlederived
material with crustal material. The most primitive isotopic values are similar
to those obtained from the carbonatites and nepheline syenites, indicating the same
mantle source gave rise to the magmas that were subsequently emplaced as the
Seiland Igneous Province. The homogeneous trace element content of the different
mafic rocks most likely indicates a relatively homogeneous mantle source for the
original magmas of the province, which has subsequently been affected by processes
of assimilation and crustal contamination. The monzonitic and dioritic bodies in the
Seiland Igneous Province are not derived from melted silicic crustal material and
may have been formed by the melting of pre-existing mafic material.
The new geochronology invalidates the metamorphic framework previously
proposed for the Seiland Igneous Province, which postulated several orogenic events
between the emplacement of the magmas and the Caledonian Orogeny. There is no
evidence for metamorphic activity in the period between 570 Ma and 420 Ma, and
there are monazites in gneissic rocks hosted within mafic rocks of Seiland age that
preserve an age of 640 Ma. This leads to the conclusion that only one metamorphic
event, the 420 Ma Caledonian Orogeny caused by the collision of Baltica and
Laurentia, affected the Seiland terrane after the emplacement of the Seiland magmas.
The new data obtained lead to a model for the evolution of the Seiland Province in
which a number of heavily modified and contaminated mantle-derived mafic
magmas derived from the mantle were emplaced into the continental crust of the
Seiland nappe between 560 and 570 Ma. This magmatism was accompanied by the
injection of alkaline magmas into the same area of the crust, and the melting of mafic
rock emplaced earlier. This magmatic event is considered to have occurred in an
extensional stress regime, possibly during intracontinental rifting or back-arc
spreading. This event took place well before the 420 Ma Caledonian Orogeny, and
thus the Seiland Igneous Province can be considered a remnant of an older geological
terrane that was emplaced onto the margin of Baltica during the Caledonian
Orogeny.

State Steering and Traditional Ecological Knowledge in Reindeer-Herding Governance : Cases from western Finnmark, Norway and Yamal, RussiaTuri, Ellen Inga January 2016 (has links)
The Arctic regions are currently undergoing transformative changes linked to globalization and climate change, which pose challenges for current governance structures. This thesis investigates governance in times of change through the lens of reindeer pastoralism, and the traditional ecological knowledge (TEK)- based management in reindeer herding. While studies increasingly highlight the benefits of incorporating TEK into governance, a central challenge remains in finding ways to ensure integration. To contribute such knowledge, this thesis analyses how reindeer-herding local management systems interact with multiple processes of governance steering reindeer pastoralism, and the ways TEK is negotiated in such interactions. Theoretically, the thesis draws on literature on multi-level governance as an analytical framework for engaging with different types of governance processes and actors, and the literature on TEK to conceptualize local social institutions. Methodologically, a qualitative bottom-up methodological strategy (with local reindeer-herding groups and constellations – siidas, brigadas – forming the central starting point for the research) was adopted, focusing on cases from reindeer pastoralism in western Finnmark in northern Norway and Yamal in northwest Siberia. The results show that local reindeer herding organizations are incorporated into processes of governance through participatory, representative and deliberative processes for decision-making. Yet, such incorporation has not facilitated integration of the TEK to processes of governance. A central challenge is that current governance processes are formalized in a way that do not accommodate non-scientific ways of knowing, or non hierarchical consensus-based decision- making. The thesis thus highlights the need for holistic strategies for how to include TEK in governance. Co-management and participatory processes alone are not enough. / IPY EALÁT, the Reindeer Herders Vulnerability Network Study / RUF: Forvaltning i endring
