You can submit your abstract hereâ?¦ https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/call-for-abstracts__;!!IKRxdwAv5BmarQ!a-FrI3weSIckuD2q8JHR__k7JkL7vI3ij960LBfk2Fwjo_Z469l-AHeZbXC4DuhSKMVCreIL8wrgmQN_$ <https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/call-for-abstracts__;!!IKRxdwAv5BmarQ!aYAHzaCfF31Rs1aYvVt-Rafd0ehuT23bqR9mWLlW68TX1IbZg82YKrLUVZ1s5Zj5kYNUor3OXSB42f3e8Cc$> We cannot wait to see you there! Warm wishes, Dr Will Hutchison, Dr Karen Fontijn and Dr Finn Illsley-Kemp (conveners) *Session description* Continental rifts represent zones of incipient to advanced lithospheric breakup, leading to the onset of oceanic spreading. The vast majority of continental rifts are associated with magmatism and account for ca. 10% of Earthâ??s active volcanoes. Rift volcanoes have historically been less active than arc volcanoes, and are therefore comparatively understudied, with many questions remaining on the magnitudes and timescales of activity, compositional controls on eruptive style, their interaction with extensional tectonics, and the related hazards and environmental impacts. Most magmatism associated with continental rifts has a highly alkaline nature, is often associated with carbonatite melts, and represents an important reservoir of incompatible trace elements, including rare earths. In failed rifts, fossilized magmatic intrusions offer economically significant concentrations of critical metals which are increasingly important for modern technology. In active volcanic rifts, often hosting large calderas, extensive geothermal reservoirs are actively explored and exploited as a renewable energy resource. Magmatic systems in rift settings, many of them located in densely populated areas, thus represent important resources for modern society, but crucially, our scientific understanding of these systems remains limited. In this session, we invite contributions on continental rift magmatism and volcanism, from both modern active systems and fossilized rifts. This may include studies on the magmatic-tectonic interactions and architecture of the magmatic plumbing systems, magmatic differentiation and ore-forming processes, characteristics of geothermal reservoirs, timescales and the nature of unrest and volcanic eruptions, physical volcanology, as well as hazards and risk associated with rift volcanism 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
