Dear all,
this is the first anouncement of PERIDOTITE WORKSHOP 2005 a four-days
meeting on mantle processes organized by the Working Group on Mediterranean
Ophiolites (GLOM).
It will be held on September 27-30, 2005 in Brione di Val della Torre,
Torino, ITALY.
Abstract and registration deadline is June 30, 2005.
The Workshop consists of two days of oral/poster presentations and two days
of field excursion on the Lanzo Peridotite Massif.
Some invited key-note speakers (J-L. Bodinier, F. Boudier, H. Downes, G.
Manatschal, A. Nicolas, G. Ranalli, M. Seyler, J. Snow, G. Suhr, R.L.M.
Vissers) will give general lectures on the “state of art” on the most
preminent mantle processes from different geological-geodynamic and
petrologic-geochemical approaches.
This Meeting is aimed to compare the up-to-date mineralogical, petrologic,
geochemical and structural knowledge of mantle rocks brought to the surface
during volcanic activity (peridotite xenoliths), exposed at the surface as a
result of tectonic processes (orogenic and ophiolitic peridotite massifs) or
sampled on the ocean floor (abyssal peridotites). Recent researches
demonstrate that most of the mineralogical and geochemical features of the
mantle rocks sampled at lithospheric levels, i.e. xenoliths in basalts and
kimberlites, orogenic and ophiolitic peridotite massifs, and abyssal
peridotites, are the result of the interaction with melts migrating through
the lithospheric mantle column. Accordingly, particular attention will be
dedicated to the processes of depletion, refertilization, thermochemical and
thermomechanical erosion of the lithospheric mantle, and of
asthenosphere/lithosphere interaction that are produced by the diffuse and
reactive percolation of asthenospheric melts through the mantle lithosphere.
The Meeting is of particular interest for presenting results of petrologic,
geochemical, geophysical, structural and isotopic researches on orogenic
continental and ophiolitic peridotites, abyssal peridotites and mantle
xenoliths in basaltic and kimberlitic volcanites.
The abstracts will be published in a regular Ofioliti issue. Critical
reviews and original papers presented at the Meeting will be published in a
Special Issue of Journal of Geodynamics.
