... the south are close to those predicted from the known Moho offset (southern stations are 0.5 s later). They rule out a stacking of the Iberian and European crusts underneath the North Pyrenean zone, as postulated in some models. In contrast, rays coming from the north give residual variations opposite...

..., are only restricted to the Cretaceous orogenic axis of the range [Internal Metamorphic Zone (IMZ) and North-Pyrenean Zone (NPZ)]. They are dated in about 20 layers known from Mediterranean coast to Garonne valley. The breccias define in this part of Pyrenees a wide and long (more than 200 km) W-E trough...

... Ma), which is related to the opening of the Bay of Biscay. The boundary between the two plates, the North Pyrenean Fault (NPF), is recognized as a major tectonic feature running E-W to the north of the range. The eastern part of the range has been later affected by the Mediterranean tectonics (about...

... of the western North Pyrenean Zone (NPZ), the Urdach massif (this paper) and the Saraillé massif (paper 2). The peridotites have been exhumed to lower crustal levels during the Cretaceous rifting period in the future NPZ. They are associated with Mesozoic pre-rift metamorphic sediments and small units of thinned...

...Helen J. Anderson Abstract Lherzolites outcrop throughout the North Pyrenean Zone of the Pyrenees and are everywhere associated with metamorphosed carbonates. It has been suggested that heat from the cooling of the lherzolites was responsible for the high temperature metamorphism of the carbonates...

... collision range [Choukroune, 1992]. A major tectonic feature is the North Pyre-nean Fault (FNP, fig. 1), which separates the Paleozoic Axial Zone to the south from the North Pyrenean Zone, made of Mesozoic sediments, to the north. Lourdes is located inside this latter unit (fig. 1). Quaternary glaciations...

In this transect, the North Pyrenean Zone is bounded to the south by gently dipping thrusts of large displacement, and the Axial...

Hammouda Abstract Felsic dikes intruding an orogenic lherzolite body from the North Pyrenean zone (France) show great compositional similarities to some of the Si-Al-Na(K)–rich glasses found as microscopic inclusions in peridotite xenoliths. As shown by Sr-Nd...

An understanding of the middle Cretaceous is critical because it corresponds in time to opening in the Bay of Biscay, to postulated strike-slip along...
