Dear Colleagues,
We would like to draw your attention to a symposium entitled "Palaeomagnetic contributions to Plate
Tectonics" to be held at the European Geophysical Society XXVII General Assembly in Nice, France,
21-26 April 2002.
Details of the symposium are given below.
The deadline for receipt of abstracts is 11 January 2002.
Submittal and general information about the meeting can be viewed at the EGS website:

With thanks for your time (and the usual apologies for multiple postings),
Antony Morris (Plymouth)

SE6.02 Paleomagnetic contributions to plate tectonics
Convener: Morris, A.; Co-Convener(s): Marton, E.; Tait, J.
Description:
Palaeomagnetic studies provided some of the critical evidence which led to the development of plate
tectonic theory in the 1960's and 1970's, principally by demonstrating: (a) that the record of
geomagnetic reversals preserved in the stratigraphic record may be correlated with that inferred
from the pattern of magnetic anomalies in the ocean basins, thereby supporting unequivocally the
Vine-Matthews hypothesis of sea-floor spreading; and (b) that the apparent position of the
geomagnetic poles had changed radically and systematically over geologic time, in a manner which can
only be explained by large-scale relative motions of the major continental blocks.
Thirty years on, palaeomagnetic studies are still providing fundamental insights across a broad
spectrum of spatial and temporal scales. This symposium will provide a forum for presentation and
discussion of recent results obtained by the international palaeomagnetic community in our attempts
to further elucidate the details of plate tectonic processes. These include: (a) the importance and
nature of rotational and translational strains in the evolution of collisional orogenic belts; (b)
the nature of deformation in fore-arc regions associated with major subduction zones; (c) the
complexities of the magnetic signal in oceanic crust; (d) rotational deformation at divergent plate
margins and during the emplacement of ophiolites; and (e) the configuration of the continents during
the Palaeozoic and Pre-Cambrian, which can only be constrained using extensive palaeomagnetic
databases.
