Proponents of the planetary growth model and other skeptics of Plate
Tectonics were quite well represented at the EGU, notably in the

No, that's not the Geodynamics session, it's the "Frontiers in Global
Tectonics - Nonconventional Ideas and Interpretations" session in the
Geodynamics group. In other words, they've accepted some papers that are
"out there" and put them in one session.
Here's the whole Geodynamics group:http://www.cosis.net/members/meetings/programme/session_programme.php...

People working with data from the Mediterranean region figure out that
Plate tectonics is outdated.
Abstracts of interest:
- CF, Pain : Fold Belts and Mountains: Collision of Plates or Collision
of Ideas?
This article states "The north-south trending Rocky Mountain Plateau is
bounded by the Park Range on the east and the Front Range to the west,
suggesting divergence." He seems to be using alternate definitions of
East and West. While the article merely states that not all mountain
ranges were necessarily formed by plate tectonics, it does not mention
expanding earth.
- Lavecchia : The Mediterranean trapped mantle plume: a lateral arm of
the Atlantic plume?
"The latter may be therefore interpreted as an independent microplate
developed in the last 35-40 Ma above a growing head plume." Uses
concepts of plate tectonics and does not mention expanding earth.
- Scalera : From Mediterranean evidence to Global tectonics and
geodynamics: a new interpretation of the active margins
Presents an alternative explanation to plate tectonics, subduction in
particular, but does not support expanding earth.
- Bell: Geochemistry of the Mediterranean mantle - geodynamic
implications
"Although a subduction-related tectonic setting has long been suggested,
many of the volcanic rocks in Italy are, in fact, similar to those
associated with intra-plate magmatism." Focuses on certain details of
the gelogy of Italy; does not support expanding earth
- Scalera : Wadati-Benioff zones
Disputes the common interpretation of mountain belts and arcs but the
abstract doesn't present what he thinks it is. Does not mention
expanding earth.
- Cwojdzinski : Supercontinents in Earth history what story do they
tell about?
Paydirt at last. "On an expanding Earth, there was only one
supercontinent - Pangea - com-posed of continental lithosphere
surrounding the planet smaller than the present Earth. The break-up
process of the supercontinent occurred only once during Earth¹s history.
Earth expansion offers a reasonable solution to main plate-tectonic
paradox that the continents could have been repeatedly separated and
returned to the same unique con-figuration within succesive
supercontinents."> - Cwojdzinski : Convection or mantle plumes?
" The presented model of the expanding Earth¹s offers a reasonable
solution to these discrepancies and paradoxes."
So basically you've picked some abstracts with interesting titles and
jumped to a delusion about their content. It will be interesting to see
how many of the articles you mentioned ever get used as references for
subsequent work.
