<p>Dear colleagues, </p>
<p>Yi-Wei Chen, Hans-Peter Bunge, Anke Friedrich, Roland Pail and
myself invite you to consider to submit an abstract in
the GD1.3 session we are organising for EGU2026 titled <i>Geophysical
modelling of vertical motion processes constrained by seismic,
geodetic and geological observations. </i></p>
<p>Our solicited speakers are Sia Ghelichkhan from ANU and Prof.
Mark Richards from UC Berkeley. The abstract of the session is
pasted below.</p>
<p>The deadline for the abstracts is the Thursday 15th of January at
13hrs CET. In the following link you can submit your abstract to
our session: <a href="https://url.au.m.mimecastprotect.com/s/-TIwCYW8NocpKMy06f0fQHxdaBP?domain=meetingorganizer.copernicus.org" class="moz-txt-link-freetext">https://meetingorganizer.copernicus.org/EGU26/abstractsubmission/55701</a>. </p>
<p>Best regards, <br>

<blockquote>
<p>Mantle convection is a fundamental process of the Earth.
Direct observations of this process are obtained through a
variety of multiscale methods. They may provide constrains to
estimate fundamental parameters for the Earth mantle structure
(e.g., viscosity, density and temperature). Seismic imaging
and gravity data, for instance, provide a snapshot of
processes occurring in the present-day mantle. Geochemical
analysis of trace elements can be used to estimate temperature
and depths of melt generation. Histories of large scale
horizontal and vertical lithosphere motion recorded in the
stratigraphic data hold important information on the evolving
mantle buoyancies. Altogether these classes of observations
would provide powerful constraints for geodynamic forward and
inverse models of past mantle convection.<br>
This session aims to provide a holistic view of the Earth
mantle and their evolution through time. We welcome
contributions from seismic tomography, anisotropy studies,
geochemistry, plate kinematics, structural geology and
theoretical models that address questions surrounding Earth’s
mantle an its evolution in the Cretaceous and Cenozoic times.
Studies using a multidisciplinary approach are particularly
encouraged.</p>
