Mantle convection and possible mantle plumes beneath Antarctica – insights from geodynamic models and implications for topography Open
This chapter describes large-scale mantle flow structures beneath Antarctica as derived from global seismic tomography models of the present-day state. In combination with plate reconstructions, the time-dependent pattern of palaeosubducti…
Integrated geophysical-petrological modelling of the Eifel region Open
We present an integrated geophysical-petrological model of the Eifel region. The Eifel is a volcanic active region in West Germany that exhibits Tertiary as well as Quaternary volcanism. One suggestion for the source of this volcanism is a…
Modelling Antarctica’s lithospheric structure and testing the West Antarctic mantle plume hypothesis Open
Numerous unresolved issues exist regarding the lithosphere of Antarctica, especially in terms of its fundamental density, temperature, and compositional structure. Estimates of total lithospheric thickness typically involve assumptions on …
Antarctic geothermal heat flux: past, present and future perspectives Open
Geothermal Heat Flux (GHF) measurements and estimates of GHF via geophysical and thermal modelling are required to better predict past, present and future Antarctic ice sheet behaviour, including its dynamic responses to ocean and climate …
Variable Melt Production Rate of the Kerguelen HotSpot Due To Long‐Term Plume‐Ridge Interaction Open
For at least 120 Myr, the Kerguelen plume has distributed enormous amounts of magmatic rocks over various igneous provinces between India, Australia, and Antarctica. Previous attempts to reconstruct the complex history of this plume have r…
How plume‐ridge interaction shapes the crustal thickness pattern of the <span>R</span>éunion hotspot track Open
The Réunion mantle plume has shaped a large area of the Earth's surface over the past 65 million years: from the Deccan Traps in India along the hotspot track comprising the island chains of the Laccadives, Maldives, and Chagos Bank on the…
Major influence of plume‐ridge interaction, lithosphere thickness variations, and global mantle flow on hotspot volcanism—The example of <span>T</span>ristan Open
Hotspot tracks are thought to originate when mantle plumes impinge moving plates. However, many observed cases close to mid‐ocean ridges do not form a single age‐progressive line, but vary in width, are separated into several volcanic chai…
