Hello dear
congratulations for the meeting. I will be in Corsica at a school on
exobiology at that time. Too bad because sounds interesting.
I did try make a package of several hundreds microns of filements
scratched from the sample your student send me but we failed to have a
good signal mainly because there were too much rock mixed and not enough
filaments. All filaments do not contain NiS2 core and therefore serpentine
host was too important.
The physicists on the line would be OK to do again the Buk analysis. IT
would be necessaty to have a thin layer of filaments put in between two
mylar (thin plastic devoid of chemical pollutant) to be installed on a
sample holder dedicated to the line. I have taken n Paris the stuff to
prepare it. If you have more samples of filaments lining on
calcite-serpentinite interface to be delicately scrtched on the support,
it would be great so we can test if we found the SH radicals signal.
Hope eveything is OK and that you enjoyed your WE
kisses

> 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

> 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.
