Scope of the workshop
After a 2-years break imposed by the Covid-19 pandemic, the European Center for Geodynamics and Seismology (ECGS) was pleased to organise the 101st edition of its meeting series Journées Luxembourgeoises de Géodynamique (JLG), held from 5 to 7 September 2022 in Luxembourg. The JLG are intended to serve as a platform for scientists throughout the various disciplines of the Earth Sciences to meet and discuss in a rather informal setting in order to foster the international collaboration.
This 101st edition of the JLG was dedicated to the subject of Intracontinental basaltic volcanic fields and was co-organized between the GFZ German Research Centre for Geosciences and ECGS. In western Europe, two such significant volcanic systems, the Eifel Volcanic Field (EVF) in Germany and the Massif Central in France, are presently considered active, although none of them has erupted in historical times. In particular in the EVF, signs of unrest such as earthquakes typical for volcanic environments and significant surface uplift have been detected in recent years. These observations raise important questions on the underlying processes and potential consequences, highlighting the need for an in-depth study of these systems.
The 101st JLG meeting placed itself in the context of the major scientific initiative led by the MAARE consortium in Germany. While the focus region of the meeting will therefore naturally be the near-by Eifel Volcanic Field (EVF), the meeting aimed at fostering a holistic view on this type of volcanic systems in general, including all relevant disciplines such as geophysics, volcanology, geodesy, geochemistry, geochronology, geology, petrology, etc. Therefore, contributions on all target regions that provide insight into intracontinental volcanic fields, such as the Massif Central in France, were warmly welcome.
