Dear Colleagues, let me call your attention to the following Session at the
next EGU 2007 General Assembly (Vienna, Austria, April 15-20th, 2007):
TS6.1 Strike-slip tectonics in ancient and modern oceanic settings
Convener: Fabrizio Storti ("Roma Tre" University)
DEADLINE FOR RECEIPT OF ABSTRACTS
15 January 2007
__________________________________________________________________________________
Strike-slip deformations play a primary role on the kinematics of the outer
part of our planet. The recognition of transform faults and of their
interactions with destructive and constructive plate margins was central to
the emergence of the Plate Tectonic theory. Transform faults form active
plate boundaries. As they pass into the plate interiors, oceanic transform
faults become large bathymetric belts known as fracture zones, which are
commonly described as tectonically quiescent features. The notions of soft
plates and diffuse plate boundaries contribute to at least partially relax
one of the basic assumptions of Plate Tectonics, i.e. the rigid behaviour
of the lithosphere in the plate interiors. Consequently, the strict
separation between tectonically active transform faults and inactive
fracture zones may not work everywhere in the global plate circuit. Indeed,
there is a growing body of evidence indicating that strike-slip
deformations at transform plate boundaries may pass to fracture zones and,
eventually, to the interior of the continents, forming large intraplate
strike-slip deformation belts. The potential impact of the notion of the
intraplate accommodation of oceanic transform shear on Plate Tectonics
encourages specific studies on this, particularly on the oceanic side. The
aim of this session is to provide a forum for researchers working on
ancient and modern oceanic transform faults and fracture zones, trying to
better understand their differences and similarities, and the along-strike
transition between them. This is a typical multidisciplinary effort and,
consequently, contributions from the widest spectrum of the Earth Sciences
are solicited.
