Scientific Commitee: Beccaluva L., Bonadiman C., Piccardo G.B., Rivalenti G., Siena FDear colleagues,

we would like to draw your attention to the above mentioned workshop, which aims to gather the petrological knowledge which has been acquired in recent years on

European lithospheric mantle by several research groups in Europe or abroad. This has been mainly achieved through the direct study of mantle material or through the

inverse approach using basic magma compositions. The various depletion and enrichment processes which affected the European mantle since Archaean times will be addressed, as well as their outcome on the origin of geochemical components and basic magma petrogenesis. Much work has been carried out on most of the principal outcrops, both peridotite massifs, mantle xenoliths and basalts. This workshop would create the opportunity to compare the various datasets and different understanding that each individual or groups have acquired trying to develop an homogeneous and coherent framework within which the petrological evolution of the European mantle would be hopefully constrained. Particular emphasis will be dedicated to the results

from in situ trace element and isotope analyses, which has been giving an outstanding push to geochemistry and petrology in recent years. Technology

development has in fact brought some of these analyses almost to the routine level allowing the accumulation of a great amount of new data, which started opening a

window for a new understanding of the relationships between lithosphere, asthenosphere and biosphere.

Contributions dealing with the direct investigation of mantle xenoliths, or larger mantle occurrences such as alpine, abyssal and ophiolitic peridotites which allow a physical observations of mantle material at various scale, are welcome, as well as those using primary magma compositions as an inverse approach to constraint the

chemical features of the mantle source on a global scale.

Ferrara, Italy, 29-31 August 2007 http://www.geoitalia.org/

The workshop is part of the 6° FIST Congress GEOITALIA2007. It will be held in the beautiful medieval city of Ferrara.
