During post-rift lithospheric thickening, carbon-rich fluids and low-degree melts can become incorporated into the newly formed lithospheric mantle, creating a spatially extensive and long-lived carbon reservoir. Mantle-derived CO<sub>2<\/sub> can subsequently migrate across the Moho and become stored in the lower crust, particularly within garnet, graphite, and accessory minerals, allowing carbon to remain trapped for millions of years before being released. Evidence from the Pannonian Basin therefore suggests a multistage carbon (fluid) pathway\u2014from asthenospheric accumulation through storage in the mantle and lower crust to eventual transport into groundwater or to the surface\u2014rather than direct mantle-to-surface degassing. Isotopic signatures and potential fluid pathways, such as nanochannels, deep faults, former volcanic conduits, and deformation zones, further demonstrate how these deep reservoirs can remain connected to present-day crustal and surface carbon systems.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" onclick=\"jQuery('#NicholasDygert').slideToggle(300)\" style=\"background: rgb(220, 120, 120); border-radius: 5px; color: #fff; padding: 5px 10px; cursor: pointer;\"><strong>Nicholas Dygert<\/strong><\/h2>\n<div id=\"NicholasDygert\" style=\"display: none;\">\n<figure class=\"wp-block-image alignright size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"683\" height=\"1024\" src=\"https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-683x1024.jpg\" alt=\"\" class=\"wp-image-1096\" style=\"width:239px;height:auto\" srcset=\"https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-683x1024.jpg 683w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-200x300.jpg 200w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-768x1152.jpg 768w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-1024x1536.jpg 1024w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-1365x2048.jpg 1365w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/08\/Nicholas-Dygert-scaled.jpg 1707w\" sizes=\"auto, (max-width: 683px) 100vw, 683px\" \/><\/figure>\n\n<div class=\"ks_text\">\n<p><strong>Nicholas Dygert<\/strong><\/p>\n<p>Department of Earth, Environmental and Planetary Sciences, University of Tennessee, USA<\/p>\n\n<p><em>Nicholas Dygert is the Lawrence and Dawn Taylor Associate Professor at the University of Tennessee.

In this talk, new constraints on the lithosphere, with particular attention to the upper-mantle structure of the region, based on P-to-S and S-to-P receiver function analysis, will be presented. The study combines broadband seismic data from more than 860 permanent and temporary stations, spanning two decades of observations.

Their origin remains debated, involving vertical plume accretion, lateral subduction-accretion, or combined plume-sagduction. Although generally stable, some cratons &#8211; such as the eastern North China Craton &#8211; experienced severe lithospheric thinning and destruction. Mantle xenoliths record a transition from a thick, refractory Archean\u2013Paleoproterozoic root in the Paleozoic to thin, fertile oceanic-type mantle by the Cenozoic, peaking at 120\u2013130 Ma. This destruction was mainly driven by Paleo-Pacific slab subduction, involving flat subduction, rollback, thinning, and replacement. Comparison with the South China Craton indicates that prolonged pre-weakening (>500 Myr) is a critical precursor, explaining the rarity of global craton destruction. Mantle plumes also drive thinning and correlate with mass extinctions and large igneous provinces, yet most cratons survive. This paradox is resolved by recratonization &#8211; post-plume root re-stabilization &#8211; as in the Slave craton after the 1.27 Ga Mackenzie event, and inferred for Kaapvaal and Tarim. Plumes may also weld terrains into refractory roots. Craton evolution is thus governed by destructive and restorative processes. This talk will comprehensively cover the dynamic life cycle of cratons.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" onclick=\"jQuery('#DavideNovella').slideToggle(300)\" style=\"background: rgb(220, 120, 120); border-radius: 5px; color: #fff; padding: 5px 10px; cursor: pointer;\"><strong>Davide Novella<\/strong><\/h2>\n<div id=\"DavideNovella\" style=\"display: none;\">\n<figure class=\"wp-block-image alignright size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"388\" height=\"518\" src=\"https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/09\/Davide-Novella.jpg\" alt=\"\" class=\"wp-image-1245\" style=\"width:239px;height:auto\" srcset=\"https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/09\/Davide-Novella.jpg 388w, https:\/\/emaw2027.epss.hu\/wp-content\/uploads\/2026\/09\/Davide-Novella-225x300.jpg 225w\" sizes=\"auto, (max-width: 388px) 100vw, 388px\" \/><\/figure><\/figure>\n\n<div class=\"ks_text\">\n<p><strong>Davide Novella<\/strong><\/p>\n<p>Department of Geosciences, University of Padova (Italy)<\/p>\n\n<p><em>I am interested in the composition and evolution of the deep Earth.
