International audience; Although they are famous among Earth scientists, the Lherz peridotites are exposed within geological formations of the North Pyrenean Zone (NPZ) still lacking detailed investigations. Our study focuses on the metasediments of

Hercynian metamorphism in the axial zone of the Pyrenees is mainly represented by a low-pressure (LP) episode with andalousite–sillimanite, but a later kyanite-bearing medium-pressure (MP) event has been described in the most oriental part of the c

Slices of ultramafic rocks from the subcontinental Pyrenean mantle, emplaced in the north Pyrenean zone, mainly consist of layered lherzolites and anhydrous pyroxenites. In the lherzolite massifs of the Ariege, the layering is cross-cut by dykes of a

The Cretaceous alkaline magmatism from the North-Pyrenean Rift Zone consists of a variety of effusive and intrusive rocks: basalts, trachytes, lamprophyres, gabbros, teschenites, ultramafic cumulates and nepheline syenites. An extensive survey of the
