Nordic Geological Winter Meeting
Date: Wednesday, January 10, 2018 — Friday, January 12, 2018
Web: http://2dgf.dk/foreningen/33rd-nordic-geological-winter-meeting/
Includes the following sessions:
1.1. Hotspots and intraplate magmas: mantle sources, magmatic processes and metasomatism
Convenors: Nina Soager (ns@ign.ku.dk), Valentin Troll (valentin.troll@geo.uu.se), Abi Barker (abigail.barker@geo.uu.se)
This session invites contributions that explore the mantle geochemistry, petrology and dynamics of intraplate volcanism both in oceanic and continental settings. We welcome studies of the temporal and spatial evolution of mantle plumes in terms of composition, temperature, sources, magma chamber processes and surface expressions. We also encourage contributions addressing mantle metasomatism, the interaction between asthenospheric melts and lithospheric mantle and the tectonic processes triggering intraplate magmatism. We invite research that explores the geochemistry of bulk lavas (including isotopes), melt inclusions, single phases (including mineral-mineral and mineral-melt equilibria) or xenoliths from intraplate volcanic settings such as ocean islands, intracontinental basaltic fields and highly alkaline rocks.
1.3. Understanding large igneous provinces and associated rapid environmental changes: from the North Atlantic Igneous Province and beyond
Convenors: Sverre Planke (planke@vbpr.no), Christian Tegner (christian.tegner@geo.au.dk), Dougal Jerram (dougal@dougalearth.com)
Large Igneous Provinces (LIPs) are known to correlate in time with periods of mass extinctions and global warming in Earth history. This session aims at presenting new observations and results on; the formation of lips, on mass extinction intervals, and on the possible causal relationships between lips and associated environmental changes. This may include stratigraphic and proxy records of mass extinction, documentation of the petrology, chronology and geophysics of lips, petrogenetic processes, links to modern plume related volcanism, and modelling. Focus will be on the North Atlantic lip and how it may have triggered the Paleocene-Eocene thermal maximum (PETM). However, contributions on other lips and environmental crises, such as the end-Permian, the end-Triassic, and the end Cretaceous extinctions, are also welcome.
Lyell Meeting 2018: Mass extinctions – understanding the world’s worst crises
Date: Thursday, March 8, 2018 — Thursday, March 8, 2018
Web: https://www.geolsoc.org.uk/lyell18
Convenors: Paul Wignall (p.b.wignall@leeds.ac.uk), David Bond (d.bond@hull.ac.uk)
The study of mass extinctions is one of the most interdisciplinary research areas within Earth and environmental sciences. Recent, major advances have come from a broad spectrum of fields, including atmospheric modelling, high-precision age dating, volcanology, geochemistry, stratigraphy and palaeontology.
The 2018 Lyell Meeting aims to highlight these achievements and showcases the improved understanding we now have of the great environmental catastrophes of the past. The Meeting aims to encompass the full spectrum of crises seen in the Phanerozoic fossil record.
The 2018 Lyell Meeting provides a platform to assess the current stratigraphic and geochemical records of environmental change during mass extinction events and the role of atmospheric climate modelling in understanding the causes of the crises. The goal is to evaluate the relative importance of environmental changes in major episodes of species extinctions, and to further explore the mechanisms that link these proximal kill mechanisms to the ultimate drivers, such as large igneous province eruptions and meteorite impacts.
This will be a rare opportunity to hear research developments happening in diverse disciplines applied to all mass extinction events.

Includes the following sessions:
EA36: Igneous processes and climate change over all of Earth history
Volcanism and igneous activity have led to weather and climate change on time scales ranging from billions of years to hours. With recent climate change impacting the destiny of our planet, petrologists have important contributions to make in understanding how Earth's climate is evolving. This session welcomes presentations on how igneous activity created Earth's earliest environments through to how historical eruptions impacted weather and climate.
Includes the following post-conference one-day short courses:
Large igneous province research frontiers (including resource explanation and climate change)
Date: 22 June
Facilitator: Richard Ernst (richard.ernst@ernstgeosciences.com)
This one-day short course will provide a provide a ‘state of the art’ training in all aspect of Large Igneous Provinces (LIPs) with a focus on research frontiers related to resource exploration and environmental/ climate change. The basics will be covered in the morning sessions: continental and oceanic flood basalts and their plumbing systems (layered intrusions, sills, dykes & deep crustal underplating). There will be an overview of additional topics: Archean LIPs, planetary analogues, associated Silicic LIPs (SLIPs), carbonatites and kimberlites, origin (plume & alternatives), links to continental breakup and the supercontinent cycle, geochemistry, associated topographic effects (regional uplift & basin formation) & associated compressional tectonics. The afternoon sessions will first focus on links with resource implications (metallogeny, oil/gas and aquifer systems). The links with a broad range of commodity types are captured in our 5-part classification system and we will also present our latest strategies for using the LIPs record in multi-commodity, multi-scale exploration targeting. The second afternoon focus will be on the rapidly developing links with dramatic environmental & climate change including mass extinction events. We summarize the latest research on the role of LIPs (and SLIPs) in dramatically changing atmospheric and oceanic composition through time, including global warming, glaciations, anoxia, step-wise oxygenation, acid rain/ocean acidification, enhanced hydrothermal and terrestrial nutrient fluxes, and mercury poisoning.

04h Large Igneous Provinces, environmental change and mass extinctions: the deadly kiss of LIPs
Convenors: Feifei Zhang (fzhang48@asu.edu), Aisha Al-Suwaidi (aalsuwaidi@pi.ac.ae), Richard Ernst (richard.ernst@ernstgeosciences.com), Ying Cui (ying.cui@dartmouth.edu)
There is an increasing recognition of the role of Large Igneous Provinces (LIPs) in major environmental perturbations and mass extinction events. LIPs can affect the atmosphere and ocean through a wide array of processes including, but not limited to, carbon cycle perturbations, global warming, global cooling, acid rain, ash clouds, and enhanced hydrothermal and terrestrial nutrient fluxes . Some of these factors, in return, can lead to mass extinctions through eg. ocean anoxia and acidification and mercury poisoning. However, our current understanding of the connections between LIPs, environmental change, and mass extinctions is incomplete in many ways. The goal of this session is to bring together researchers approaching this problem from multiple perspectives. We welcome contributions that show: (1) geological, geochemical evidences of LIPs throughout geological time; (2) geochronological constraints on LIPs, (3) the interactions between the effects (direct and indirect) of LIPs and climatic change, (4) reconstructing changes in global weathering regime across the LIPs, (5) spatiotemporal constraints on marine chemical conditions (e.g., redox conditions, and ocean acidification) throughout LIPs from inorganic and organic proxies; (6) investigations of causal links between LIPs, environmental conditions, and the diversity and ecological structure of marine ecosystems during mass extinctions and subsequent recoveries. While these themes are best developed in the Phanerozoic we are also interested in contributions that identify Precambrian examples.

Includes the following sessions:
T011. Current understanding of large igneous provinces, hotspot tracks, and mantle plumes
Convenors: William Sager (wwsager@central.uh.edu), Anthony Koppers (akoppers@coas.oregonstate.edu), Cornelia Class (class@ldeo.columbia.edu), Trond Torsvik (t.h.torsvik@geo.uio.no)
Hotspot tracks and large igneous provinces (LIPs) are surface features often attributed to focused mantle upwellings (mantle plumes). As observations conflicted with early, purely thermal plume models, more complex models were developed, including variations in time and chemical composition. Plume upwellings may originate at several levels in the mantle and many likely have a link to large low shear-wave velocity provinces (LLSVPs) near the core-mantle boundary. However, the role of plumes in some LIPs is a matter of debate. Hotspot volcanic chains display complexities in age progression, plume motion, geochemistry and tectonic evolution that imply modulation of volcanism by mantle convection and plate tectonic processes. We seek contributions from various perspectives, including geochronology, geochemistry, geophysics, and volcanology that present new data, models, or interpretations about LIPs, hotspot tracks and mantle plumes.
