Dear Geodynamics community,
<div class="">
<div class="">
<div class="">
<div class="">
<p class="">we would like to draw your attention to a new
session focussing on the evolution of cratonic lithosphere
that will be hosted at next year's EGU,<span
class="link-coloured"><br>
</span></p>
<p class=""><span class="link-coloured">GD 7.2 - Evolution
of cratonic lithosphere: Variability, geodynamic
interactions and resource potential</span><span
class="toggle-arrow"></span> <br>
</p>
<p class="">Inputs of multiple disciplines are essential to
address this fascinating and multifaceted topic. This
session welcomes therefore contributions from a wide range
of disciplines, which include, but are not limited to,
seismology, gravity and magnetic studies, geodynamics,
tectonics, geochemistry, and petrology.<br>
</p>
<p class="">Would you be interested in submitting an
abstract, we invite you to read the session description
below for more details.<br>
</p>
<p class="">We are happy to have Graham Pearson and Heather
Bedle as keynote speakers in our session. </p>
</div>
</div>

<div class="">
<p class="">Looking forward to seeing many of you at EGU,</p>
Peter Haas, Nicolas Celli and Andrea Tommasi (Conveners<span

<div class="">Cratons form the ancient, stable cores of most of
the Earth’s continents. Knowledge about the present-day
architecture of cratons is the key to understand the evolution
of continental plates. In addition to that, cratons concentrate
many economically relevant mineral deposits, which are
indispensable for a modern society. For many cratonic regions
however, little is still known about the present-day
lithospheric structure and how it evolved since the Archean,
mainly due to their remoteness and harsh local environmental
conditions. Ongoing data acquisition, as well as the usage and
optimization of remote and passive techniques have shed new
light on the lithospheric architecture of cratonic regions.
Recent advancements across several disciplines show that cratons
are more varied and fragmented than previously assumed, which
has strong implications for geodynamic interactions with the
convective mantle and long-term stability.<br>
In this session, we welcome contributions across different
scales that describe the cratonic lithosphere and its evolution
with time, up to the dawn of plate tectonics. We aim to address
topics like: characterization and evolution of cratonic crust
and lithosphere; coupling between cratonic crust and mantle;
mechanisms to form, maintain and destroy cratonic roots;
craton-plume interaction; the role of cratons in supercontinent
configurations; connection of cratons to mineral deposits.<br>
We would like to raise discussions within a multidisciplinary
session and therefore welcome contributions across a wide range
of disciplines, including, but not limited to geodynamics,
geology, tectonics, seismology, gravity, geochemistry,
petrology, as well as joint approaches.</div>
