Geological Society of America (GSA) Northeastern Section 48-th Annual Meeting

Date: Monday, March 18, 2013 — Wednesday, March 20, 2013

Location: Bretton Woods, New Hampshire, USA

Web: http://www.geosociety.org/Sections/ne/2013mtg/index.htm

Includes the following session:

T18: Mesozoic igneous features of northeastern North America: magmatic origins and links to tectonic events

 

Convenors: Gregory McHone (greg@earth2geologists.net), John Puffer (jpuffer@andromeda.rutgers.edu), Nelson Eby (g_eby@uml.edu)

 

Several great magmatic events in northeastern North America are recorded by overlapping provinces of Triassic, Jurassic, and Cretaceous dikes, sills, lavas, and plutonic complexes. They provide clues for the origins of mantle basalts, crustal melting, differentiation of magmas, formation of composite volcanoes, and major fissure eruptions with their environmental impacts. In addition the magmatic events are linked to specific tectonic features and Early Mesozoic rift basins of Pangaea as it separated into new continents and opened the Atlantic Ocean. We invite presentations on both specific features and more general models to describe and explain the origins and significance of these Mesozoic magmas and events.



Volcanism, Impacts and Mass Extinctions: Causes and Effects

Date: Wednesday, March 27, 2013 — Friday, March 29, 2013

Web: http://massextinction.princeton.edu/

Organising committee: Gerta Keller (gkeller@princeton.edu), Andrew Kerr (kerra@cf.ac.uk), Norman MacLeod (n.macleod@nhm.ac.uk), Mike Widdowson (m.widdowson@open.ac.uk), Vincent Courtillot (courtil@ipgp.fr), Ashok Sahni (ashok.sahni@gmail.com), Thierry Adatte (thierry.adatte@unil.ch)

This conference brings together researchers across the geological, geophysical, and biological disciplines to assess the state of research into the causes of mass extinction events. The main goal is to evaluate the respectiveroles of volcanism, bolide impacts, sea level fluctuations and associated climate and environmental changes in major episodes of species extinction.

Over the past 30 years considerable research efforts have been directed toward understanding the context and nature of environmental changes that occurred immediately prior to, at, and after the five major Phanerozoic mass extinctions. Important new data and observations have emerged from the fields of palaeontology, stratigraphy, sedimentology, geochronology, geochemistry, mineralogy, volcanology, geophysics, palaeomagnetism and astrophysics. Consequently, a critical review of these data — and their implications with respect to identification of the cause(s) of these eco-evolutionary events — is warranted. The conference is intended to foster a new, collaborative, interdisciplinary approach to resolving outstanding problems in this field.

Geological Association of Canada-Mineralogical Association of Canada (GAC- MAC) Joint Annual Meeting

Date: Wednesday, May 22, 2013 — Friday, May 24, 2013

Location: Winnipeg Convention Centre, Winnipeg, Manitoba, Canada

Web: http://gacmacwinnipeg2013.ca/index.html

Includes the following sessions:

SS-8: Testing links among large igneous provinces, iron formations, and volcanogenic massive sulfide deposits

Convenors: Andrey Bekker (bekker@cc.umanitoba.ca), Richard Ernst (richard.ernst@ernstgeosciences.com), Wouter Bleeker (wouter.bleeker@nrcan.gc.ca)

Emplacement of Large Igneous Provinces (LIPs) has been linked to mantle plume events. It has been also argued that submarine hydrothermal activity associated with mantle plume events contributed to enhanced delivery of base metals, iron and manganese to the oceans, favouring formation and preservation of VMS deposits in back-arc settings and iron and manganese deposits on continental shelves. Growing age resolution for LIPs, IFs, and VMS deposits allows now to test temporal association among mafic to ultramafic magmatic activity and these deposits, as well as explore potential cause-and-effect relationships. Submissions providing temporal resolution on LIPs, IFs, and VMS deposits, dealing with specific deposits and mantle plume events, and exploring cause-and-effect relationships are encouraged.          

SS-9: Layered intrusions: new paradigms and approaches to understanding magmatic processes

Convenors: James Scoates (jscoates@eos.ubc.ca), Jim Miller (mille066@tc.umn.edu)

Layered intrusions have long captivated geologists with their remarkable textures and structures that record the diversity of processes of magma differentiation, recharge, and venting. They are also host to a range of magmatic and hydrothermal mineral deposits whose formation is intrinsically tied to the emplacement and crystallization histories of these bodies and their interaction with country rock. Recent progress in concepts concerning the evolution of layered intrusions is based on integrated studies involving field observations, textural interpretations, experiments, fluid dynamic modeling, and geochemistry and geochronology. Contributions on all subjects relevant to advancing our understanding of processes involved in the development of layered intrusions are strongly encouraged.    

Also includes the following fieldtrip:

Neoarchean mafic-ultramafic intrusions in the Bird River Greenstone Belt: tectonic setting and economic significance

Leaders: Paul Gilbert (paul.gilbert@gov.mb.ca), James Scoates (jscoates@eos.ubc.ca), Jon Scoates, Eric Yang (eric.yang@gov.mb.ca), Caroline Mealin (cx_mealin@laurentian.ca), Michel Houle (michel.houle@nrcan.gc.ca), Carey Galeschuk (cg@mustangminerals.com)

A-5: Deep Earth processes through geochemistry

Convenors: Youxue Zhang (youxue@umich.edu), Yigang Xu (yigangxu@gig.ac.cn), Jianping Zheng (jpzheng@cug.edu.cn)

Petrological and geochemical studies often shed light on deep Earth processes. For example, petrology and geochemistry of large igneous provinces and hotspots may reveal mantle signature from the core-mantle boundary, and petrology and geochemistry of ultra-high-pressure metamorphic rocks can provide information on subduction and exhumation. This session will focus on solid Earth geochemistry, including igneous and metamorphic petrology, experimental petrology, trace element and isotope geochemistry, and mineral physics, and their applications to understand deep (from crust to the core-mantle boundary) Earth processes.

Invited speakers: Roberta Rudnick (University of Maryland), Yingwei Fei (Carnegie Institution of Science), Hongfu Zhang (Chinese Academy of Sciences)

1-2: Frontiers in large igneous provinces research: a tribute to the life and career of John Mahoney

Convenors: Loyc Vanderkluysen (loyc@asu.edu), Marissa Tejada, Millard Coffin (m.coffin@noc.soton.ac.uk)

Large igneous provinces (LIPs) are the largest manifestations of volcanism on Earth. They are anomalous both in terms of the volume and length of lava flows erupted at the surface and in terms of the scale of mantle melting necessary to produce them. They are also thought to have widespread impact on climate and the environment. This session would welcome all contributions to LIP research, with particular emphasis on:

  • developments in the modeling of thermochemical plumes
  • geophysical imaging of LIPs and their mantle source
  • petrology and geochemistry of LIPs and implications for the composition of the mantle
  • internal architecture and emplacement of LIPs
  • recent discoveries from ocean and continental drilling programs
  • climatic and environmental impacts of LIPs
  • planetary LIPs and implications for the early Earth


23-rd Annual VM Goldschmidt Conference

Date: Sunday, August 25, 2013 — Friday, August 30, 2013

Location: Firenze Fiera Congress Centre, Florence, Italy

Web: http://goldschmidt.info/2013/index

Includes the following sessions:

01e: Causes of Phanerozoic mass extinctions: impacts vs. large igneous provinces vs. others?

Convenors: Fred Jourdan (f.jourdan@curtin.edu.au), Andrea Marzoli (andrea.marzoli@unipd.it), Simonetta Cirilli (simocir@unipg.it)

The history of life on Earth is punctuated by several instances of sudden drops in biodiversity where a large number of species were wiped out, followed by biotic recovery, rapid evolution and dramatic shifts in dominant life forms. Though this phenomenon is well known, the root cause(s) of these mass extinctions is/are yet unsolved and controversial. Multiple causes have been advanced to explain sudden extinctions. Currently, the two dominant contenders are high velocity extraterrestrial bolides and large volcanic eruptions. Discussions of these two hypotheses have been recently quite polarized. Nevertheless, critical to evaluate the potential role of volcanism and asteroid impact (as well as other hypotheses) in causing mass extinctions are (1) precise temporal correlations with the stratigraphic boundaries, (2) well understood mechanisms that could alter Earth’s climate (e.g. gases from target rock vaporization or volcanogenic emission) and (3) effects of the climate changes on the biosphere. In this session, we are encouraging submission from proponents of the volcanism, asteroid impact, and any other mechanisms that could potentially explain the Phanerozoic mass extinctions. In particular, we are seeking contributions from stratigraphy, geochronology, geochemistry, physical modelling and climate studies.

Keynote speaker: Paul Wignall (University of Leeds)

06f: Continental magmatic pipeline: from crustal roots to the surface

Convenors: Karl Cooper (kmcooper@ucdavis.edu), Jonathan Miller (jonathan.miller@sjsu.edu), Josef Dufek (josef.dufek@eas.gatech.edu)

This session will focus on magmatic processes in continental sectors and their role in continental crustal evolution, addressed through a variety of approaches including petrological studies, mineral chemistry and geochronology, and numerical and/or laboratory modeling of magmatic systems. Broad topics covered in this session will include the role of deep vs. mid- to shallow-level magmatic plumbing systems in controlling silicic magmagenesis and/or the composition of continental crust and the relationship of the thermal structure and chemical differentiation of the continents. We welcome submissions covering diverse topics and approaches within this broad context, including for example: multi-disciplinary studies combining textures, chemistry, and ages, including mineral chemistry and geochronology; the role of crystal mush vs. solidified magmas (i.e., thermal histories of reservoir systems); magma mixing processes and efficiency; thermobarometry of crystals and magmas; and evidence for silicic magmagenesis by deep-seated vs. upper-crustal differentiation processes.

11c: Crustal assimilation during magma emplacement

Convenors: Luigi Dallai (dallai@igg.cnr.it), Valentin Troll (vrtroll@gmail.com)

The chemical compositions of plutonic and/or volcanic rocks (solidified magma) are generally used to constrain the compositions of the source from which the magmas were originally formed, and the physical conditions of melt generation. However, the compositions of magmas change as they ascend through the lithosphere in response to closed-system (fractional crystallization), and/or open-system (crustal contamination, magma mixing) behavior of the igneous bodies. The session focuses to the mechanisms producing chemical as well as isotopic variations, in order to resolve mantle vs. crustal contributions, and to quantify the elemental fluxes associated with such processes. The fundamental question to be addressed is how and to what extent the chemistry of igneous systems reflects source composition, or it has been modified during their ascent to shallow level magma reservoirs and volcanic extrusions/explosions. We therefore welcome insights provided by the re-interpretation of data from classical measurements and by novel isotope-geochemical techniques, and their meaning in the geological framework.

American Geophysical Union (AGU) Fall Meeting

Date: Monday, December 9, 2013 — Friday, December 13, 2013

Location: Moscone Center, San Francisco, California, USA
 
Includes the following sessions:
 
DI13A: Linking the Earth's surface with the deep interior: comparing predictions and observations of mantle plumes
 
Convenors: Maxim Ballmer (ballmer@hawaii.edu), Cinzia Farnetani (cinzia@ipgp.fr), Anthony Koppers (akoppers@coas.oregonstate.edu), Esteban Gazel (egazel@vt.edu)
 
Mantle plumes and alternative forms of mantle upwellings provide a direct window into the composition and dynamics of the Earth's deep interior. Their composition and dynamics are explored with a variety of geophysical and geochemical methods. In this session we invite contributions from seismology, geochemistry, petrology, tectonics and geodynamics on topics such as: progress in seismic imaging of mantle upwellings, understanding plume motions in the convective mantle, exploring possible links between lower mantle structures and active hotspots, constraining the origin of geochemical zonation of hotspot lavas, and evaluating the role of shallow melting processes on lava compositions.
 
V11C: Ocean islands and large igneous provinces
 
Convenors: James Day (jmdday@ucsd.edu), Jasper Konter (jasper@geo.utep.edu), Matthew Jackson (jackson@geol.ucsb.edu)
 
Despite temporally diminutive volume relative to mid-ocean ridge basalts, studies of large igneous provinces (LIP) in oceans and continents and ocean island basalts (OIB) inform on mantle evolution. LIP can represent short-duration high-productivity magmatism and some OIB require thermal/chemical mantle anomalies. Thus, OIB/LIP may require a plume source. This session aims to advance understanding of OIB/LIP magmatism. Specifically, what can OIB/LIP tell us about mantle processes, domain ages, and compositional variability? What significance do end-members (c.f., PREMA, EM, HIMU) hold in OIB and are they present in LIP? Can the timing and mass flux of outer core, subducted components and/or metasomatism into OIB/LIP mantle sources be quantified?
 
V31F: Permian-Triassic environmental and climatic extremes and biotic responses
 
Convenors: Sverre Planke (planke@vbpr.no), Samuel Bowring (sbowring@mit.edu)
 
The end-Permian is Earth's most severe extinction event and is associated with rapid global warming, perturbation of the carbon cycle, and oceanic acidification. The Siberian Traps LIP is commonly invoked as the main trigger. In this session, we invite a broad range of contributions with focus on the end-Permian and early Triassic including: plate-tectonics and geodynamics; rates, dates and chemical evolution of magmatism; volumes and geochemistry of volcanic and metamorphic gases; geochemical and environmental changes; climate evolution: data and models; paleobiology of extinction and recovery. We encourage experts from disparate fields to share new ideas to understand this singular event in Earth history.
 
V33F: Magma plumbing, transport and eruption at basaltic volcanoes
 
Convenors: Marie Edmonds (medm06@esc.cam.ac.uk), Bruce Houghton (bhought@soest.hawaii.edu), Jacopo Taddeucci (jacopo.taddeucci@ingv.it)
 
Improved volcano monitoring and data analysis present expanded possibilities for studying volcanic processes, especially those related to magma storage and transport. In addition to improved data streams, increasingly important is development of numerical and physics-based models. Frequent unrest at hotspot volcanoes provides important opportunities for studying magma plumbing systems using new data and modeling approaches. We welcome observations, interpretations, and models of transport and plumbing from hot spot volcanoes worldwide, and recent insights into factors influencing behaviors at individual volcanoes. Particularly welcome are approaches that cross disciplinary boundaries, as well as comparative studies of different volcanoes.
