Includes the following sessions:

T117. Magmas and their sources: a tribute to the distinguished career of Fred Frey

Convenors: Michael Garcia (, Michael Rhodes (, Rosemary Hickey-Vargas (

Fred Frey, 2014 MGPV Distinguished Career Award recipient, has devoted his career to studying magmas, their sources, and formation. We encourage research by those who are inspired by or have worked with this distinguished geoscientist.

P2/T206. Mass extinctions: volcanism, impacts, and catastrophic environmental changes

Convenors: David Bond (, Gerta Keller (, Thierry Adatte (

This session explores recent advances in the stratigraphic and geochemical records of mass extinctions and impacts that have seen the impact-kill scenario recede in favor of terrestrial causes that may ultimately derive from massive volcanism.

T6. Birth and death of supercontinents

Convenors: Daniel Pastor-Galan (, Brendan Murphy (, William Collins (

Earth's landmasses amalgamate altogether into supercontinents following a quasi-periodic cycle since the origin of tectonics. This session will review the tectonic evolution of supercontinents from amalgamation to break up at every level of Earth's structure.

T20. Magmatism, tectonics, and metallogeny of the Central Asian Orogenic Belt

Convenors: Wenjiao Xiao (, Bo Wan (

This session will provide an international forum for interdisciplinary discussions on accretionary orogenic belts, specifically on the Central Asian Orogenic Belt (CAOB).

T2. Emplacement of upper crustal magmatic intrusions: field studies of laccoliths, sills, and subvolcanic plugs

Convenors: Paul Wetmore (, Eric Horsman (, Charles Connor (, Scott Giorgis (

This session is focused on the emplacement and melt-host rock interactions of shallow crustal intrusions including sills, laccoliths, and subvolcanic conduits.

Recent advances in igneous processes

Convenors: Sheila Seaman (, Diane Smith (
