Abstract
Some spinel Iherzolitic xenoliths scavenged by basanites and leucito-n ephelinites from Northern Lodevois (Bas-Languedoc, Southern France) di splay mineralogical evidence of interaction between lithospheric mantl e and carbonated fluids. This interaction is associated with a recent thermal event which may be the precursor of the Plio-Quaternary alkali volcanism of Bas-Languedoc. The carbonated fluid source could be a ca rbonate-bearing mantle reservoir at depth near 100 km.
