T11. North Atlantic arcs, rifts, and plumes: Ordovician to today
Convenors: Tamara Carley (carleyt@lafayette.edu), Tenley Banik (tjbanik@ilstu.edu), Martha Withjack (drmeow3@eps.rutgers.edu), LeeAnn Srogi (LSrogi@wcupa.edu), Maryann Malinconico (lovem@lafayette.edu)
From Ordovician K-bentonites and the Mesozoic Central Atlantic magmatic province (CAMP) to Iceland’s ongoing Fagradalsfjall eruption, the North Atlantic has a long, diverse history of magmatism and volcanism. This session focuses on the generation, emplacement, evolution, and eruption of North Atlantic magmas through time, space, and tectono-magmatic settings. We especially welcome contributions from early-career researchers.

GD7.1 Lithospheric structure and mineral deposits: role of collision, subduction, extension, LIPs, and impacts
Convenors: Irina Artemieva (iartemieva@gmail.com), Shuwen Dong (swdong8888@126.com), Richard Ernst (richard.ernst@ernstgeosciences.com), Graham Begg (graham.begg@uwa.edu.au)
Lithosphere evolution, reflected in the lithosphere structure, controls the deposition of mineral resources, many of which occur in specific geodynamic settings. We invite contributions from various geophysical, geodynamic, geological, and geochemical studies, as well as from numerical modeling, which address the questions how various plate tectonics and mantle dynamics processes
- modify the lithosphere structure,
- control ore deposits,
- and how these processes changed during the Earth's evolution.
We particularly invite contributions with focus on unique ore deposits and geodynamic processes that created them.

SS-05 Cratons, cratonic magmatism and diamonds
Convenors: Yana Fedortchouk (yana@dal.ca), Maya Kopylova (mkopylova@eoas.ubc.ca), Andrew Schaeffer (andrew.schaeffer@canada.ca)
Cratons are the oldest and most tectonically stable parts of the continental lithosphere. They are home to some of the most exotic magmas on Earth including kimberlites, lamproites, and carbonatites, in addition to hosting primary diamond deposits. Methodological advances in seismic tomography studies of cratons improved our understanding of the structure and extent of cratonic mantle roots and crust as well as craton evolution. We combine geophysical information on cratons with new petrological, geochemical and geochronological data on tectonic evolution of the crust and the origin of mantle domains. Cratonic magmatism, from Archean komatiites and basalts, kimberlites and related ultramafic alkaline volcanics, provide a rich source of information on the timescales of mantle and deep crust processes. Studies of mantle-derived xenoliths, diamonds and their inclusions as well as mantle melting experiments further improve our understanding of the cratonic mantle and its modification. The session welcomes contributions across all these different fields of cratonic studies, which advance our understanding of craton formation and stabilization, mantle metasomatism and diamond formation, origin and triggers of diverse crustal and mantle magmatism and studies advancing diamond exploration techniques.

Includes the following sessions:
5i – Large Igneous Provinces: Causes and Consequences
Convenors: Hafida El Bilali, Sarajit Sensarma (sensarma2009@gmail.com), Juliana Troch (trochj@si.edu), Greg Shellnut (jgshellnut@ntnu.edu.tw), Richard Ernst (richard.ernst@ernstgeosciences.com), Steven Denyszyn (steven.denyszyn.uwa.edu.au)
The session seeks to highlight advances in understanding Large Igneous Provinces (LIPs, sensu lato, i.e. including SLIPs) and their link and consequences on mineral deposit formation, global climate, and biosphere, through chemical and physical processes in crust-mantle system, mantle source heterogeneity, emplacement histories, supercontinent cycles, and gas release through volcanism and hydrothermal alteration via the intrusive component. We invite presentations from scientists across all career levels.
