THE MEDITERRANEAN LOWER CRETACEOUS

Peridotites of Aptian-Albian age are observed in the Pyrenees at Bestiac,
southeast of Tarascon (Peybernes, 1976). In this region the Aptian-Albian
sediments are slightly metamorphosed.
Alkaline intrusions (nepheline syenites) of Albian age occur in Corbier (Fig. 33).
