ABSTRACT: A broad set of samples
from the CVP has been analyzing Pb isotopes. Campanian Volcanic Province (CVP)
has been produced by various ranges of mixing between three components: 1)
MORB, 2) Hercynian basement and 3) upper crust. Anyhow, the upper crust that
has modified the Pb isotopic composition also shows trends towards an Achaean
upper crust. This is consistent for all Mediterranean area. This is not in
contrast with the past plate tectonic reconstruction. Also the surface
sediments (GLOSS) may have been a mixing between the Achaean upper crust and a
Hercynian component with an implication worldwide due to the rock cycle
processes.
