Witrynaophiolites and SSZ ophiolites has to be done carefully and by integrating several geochemical tools. Consequently, in order to accurately assess the geochemical fingerprinting of ophiolites, it is necessary to look at the fluid-immobile element data.

As most MOR ophiolites get …

However, applying the resulting methodologies to … WitrynaThe ophiolitic rocks of the Attic-Cycladic crystalline belt are considered of key importance for understanding the Mesozoic tectonic evolution of the Aegean region. Unresolved questions concern their tectono-stratigraphic relationships across the region. The mode of occurrence of the Cycladic ophiolites varies, as they appear as: (a) dismembered …
