Includes the following symposia:

VS03 LIPs: vents and volatiles

Convenor: Ingrid Ukstins Peate (

This symposium will focus on recent advances made in our understanding of delivery mechanisms and volatile impact of flood volcanic eruptions from Large Igneous Provinces (LIPs) – mafic, silicic and bimodal. Increases in our understanding of eruption product records, volatile load and dispersal, and identification of vent sites sourcing individual eruptions provides the opportunity to re-evaluate these parameters with the goal of quantifying the current state of knowledge and guiding future targets of study. We invite papers that address the following themes: 1. Studies of LIP eruptions and vent sites as a mechanism for quantifying eruption processes. 2. Quantification of volatile fluxes on the scale of individual eruptions to LIPs. 3. Climate impact of volatiles from individual eruptions to cumulative province emplacement – especially novel volatiles such as F, Cl, Br. 4.Integrated impact of eruption mechanisms on volatile dispersal and consequences.

VS28 Understanding VIPS (Volcanic and Igneous Plumbing Systems) through Multidisciplinary Research

Convenor: Steffi Burchardt (

Volcanic and Igneous Plumbing Systems (VIPS), which are made up of e.g. magma chambers, sheet intrusions, and conduits, are characterized by complex physical and chemical interactions of magma(s) with the surrounding rocks that occur from atom- to crustal-scale, and span times from seconds to millions of years. Hence, multidisciplinary research is essential to grasp the complexity of VIPS. Diverse scientific approaches have been used to study VIPS that include: (1) volcano geodesy, seismology, and volcanic gases chemistry for studying active VIPS, (2) structural geology, igneous petrology, and geochemistry for studying fossil, eroded VIPS, and (3) laboratory, numerical, and petrological modelling studies to constrain the dynamics and evolution of VIPS. Although all these approaches focus on the same topics, they traditionally operate as independent entities, which frequently leads to contradictory views. This realisation implies that method-based approaches alone are insufficient to fully unravel the complex chemo-physical processes governing the dynamics of VIPS. Instead, a process-based approach, integrating the input from various disciplines is recommended in order to derive a comprehensive understanding of VIPS. The proposed symposium aims to provide a platform for investigations on all components of VIPS e.g. sills, dykes, laccoliths, magma chambers, volcanic conduits, and the interface between magma bodies and their host rocks. Integrating a variety of approaches, e.g. geodetic and geophysical monitoring, field studies, and modelling, the symposium will be an ideal start for a new VIPS commission of IAVCEI, which we will propose to IAVCEI shortly.
