Includes the following sessions:

Rift-related magmatism in the Circum-Atlantic margins and related mineralization

Convenors: Jarda Dostal (, Daniel Kontak (

The session will focus on various types of rift-related magmatism, and associated mineralization, which formed during different stages of development of the current circum-Atlantic region. This magmatism records repeated rupture and fragmentation of the continental crust through time with contemporaneous effusion of both mafic and felsic volcanic rocks or their intrusive equivalents. The session will deal with a range of related topics, including magma generation, magma evolution, lithospheric interaction, intrusive mechanisms, volcanism and mineralization which are in different ways associated with magmatic processes closely tied to continental rifting. Both oral and poster presentations are welcome. This special session is sponsored by the Volcanology and Igneous Petrology Division.


The Large Igneous Province record of North America through time

Convenors: Richard Ernst (, Mike Hamilton (, Wouter Bleeker (, Paul Sylvester (

This session will focus on large igneous provinces (LIPs) in North
America, through all of geological time, also in adjacent ocean basins
 (e.g. Iceland, the Arctic basin), and in formerly attached continental
 blocks (e.g. Europe, NW Africa, Siberia, Australia? etc.). Contributions
 on all aspects of LIP magmatism are welcome: mantle dynamics and plumes,
 the intrusive and extrusive architecture of LIPs, their interaction with sedimentary basins and hydrocarbons, the broader Earth system,
geochemistry, geochronology and paleomagnetism, paleogeographic
 reconstructions, and ore deposits.
