Dear all I would like to draw
your attention to the biannual Nordic Geological Winter meeting to be
held in Iceland during the days 9-12 of January 2012.
You are particularly invited to attend the following session on understanding volcanoes.
Dealine fro abstract is 17th of October.

THEME 2: [UV] Understanding volcanoes
Organizer: Ármann Höskuldsson
[UV 1] Volcanoes in Iceland
Conveners: Ármann Höskuldsson (armh@xxxxx) and Hannes Mattson (hannes.mattsson@xxxxxxxxxxxx)
The session will focus on volcanism in Iceland and descriptions of individual eruptions. We welcome all contributions in relations to eruption dynamics focused to describe how eruptions in Iceland did behave from beginning to end. Further, statistical analyses of eruptions at different volcanoes in Iceland are welcomed.
[UV 2] Ancient volcanism in Scandinavia
Conveners: Kari Strand (Kari.Strand@xxxxxxx) and Eirik Gjerlöw (eirik@xxxxx)
This session provides the opportunity for contributions that fall within the broad spectrum of paleovolcanology, geochemistry and tectonic settings of ancient volcanic-sedimentary terrains in Scandinavia. We encourage abstract submissions on general documentation ancient volcanic products by their geochemical composition and physical characteristics. The processes in volcanic-sedimentary terrains are complex, and include volcanism, normal surface processes and tectonics, thus possible contributions related to facies architecture of ancient volcanic centres are most welcomed. Better understandings of ancient volcanic-sedimentary depositional environments have applications in mining exploration.
[UV 3] Volcanism in the North Atlantic
Conveners: Rolf B. Pedersen (rolf.pedersen@xxxxxxxxxx) and Romain Meyer (meyerr@xxxxxxx)
A multidisciplinary examination of the North Atlantic volcanic role in plate tectonics and Earth's internal dynamics has the potential to cast new light on the interrelation-ships between these processes.
Continental breakup at the Paleocene-Eocene transition initiated the Northeast Atlantic. Early basin formation was not accompanied by significant volcanism, magmatic activity increased extensively around breakup time. We would like to address during this session observations from the volcanic events and magma evolution prior to and during continental separation (e.g. continental flood basalts, seaward dipping reflector sequences), and the post-breakup continuous activity
(including Mid-Ocean ridges and Quaternary volcanic activity on Svalbard, Jan Mayen and Iceland). It is necessary to understand those local volcanic activities in detail to also understand the origin and function of the North Atlantic geology.
Welcome are not only geochemical, volcanological and experimental data but also models regarding magma injections during rifting/drifting, mantle plumes and mantle heterogeneities, lithosphere rheology and inherited weaknesses.
[UV 4] Magma plumbing system
Conveners: Paul Martin Holm (Paulmh@xxxxxxxxx) and Christian Tegner (christian.tegner@xxxxxxxxx)
The magma plumbing of volcanic systems involve highly dynamic migration of melts in conduits and chambers, crystallization, mixing, reaction with country rocks and the hydrosphere, and eruption, and is linked to plate tectonics and structure of the crust. These processes control the compositional and textural diversity of igneous rocks, the style of volcanic eruptions, the nature of hydrothermal systems, and the deposition of metallic ore bodies. Establishing the nature and origin of volcanic plumbing systems requires integration of geophysical, geochemical and petrological observations, experiments and models for extinct and active systems. This session therefore seeks contributions from a wide range of studies shedding light on sub-volcanic processes, including volcanic roots (sills, dykes, plutons and their aureoles), extrusive rocks, and monitoring of active volcanoes.
