“…In the northern part of Spain, the Basque-Cantabrian chains, Albian-Cenomanian sedimentary rocks are extensively exposed and have experienced longterm geological and paleontological investigations (e.g., Erman 1854;Feuillée 1967;Mengaud 1921;Wiedmann 1962;Ramírez del Pozo 1972;Wiedmann and Kaufmann 1978;García-Mondéjar and Pujalte 1982;Wilmsen et al 1996;Wilmsen 1997Wilmsen , 2000Najarro et al 2009Najarro et al , 2010López-Horgue et al 2009). The Bielba Formation (uppermost Albian-lower Cenomanian) was proposed by García-Mondéjar and Pujalte (1982).…”

“…The age of the Cretaceous magmatism is often constrained by stratigraphic correlations with the sedimentary formations in which volcanic or intrusive rocks are observed (Fig. 3;San Miguel de la Camara 1952;Rossy 1988;Castanares et al, 1997;López-Horgue et al, 1999;Castanares et al, 2001;López-Horgue et al, 2009). In Buzy (Pyrénées-Atlantiques), teschenites outcrop as sills intrusive in the Turonian flysch where they developed a hornblende-hornfels contact metamorphism aureole (Casteras et al, 1970).…”

Abstract. An increasing number of field examples in mountain belts show that the formation of passive margins during extreme continent thinning may occur under conditions of high to very high thermal gradient beneath a thin cover of syn-rift sediments. Orogenic belts resulting from the tectonic inversion of distal margins and regions of exhumed continental mantle may exhibit high-temperature, low-pressure (HT-LP) metamorphism and coeval syn-extensional, ductile deformation. Recent studies have shown that the northern flank of the Pyrenean belt, especially the North Pyrenean Zone, is one of the best examples of such inverted hot, passive margin. In this study, we provide a map of HT-LP metamorphism based on a data set of more than 100 peak-temperature estimates obtained using Raman spectroscopy of the carbonaceous material (RSCM). This data set is completed by previous PT (pressure and temperature) estimates based on mineral assemblages, and new 40 Ar-39 Ar (amphibole, micas) and U-Pb (titanite) ages from metamorphic and magmatic rocks of the North Pyrenean Zone. The implications on the geological evolution of the Cretaceous Pyrenean paleomargins are discussed. Ages range mainly from 110 to 90 Ma, and no westward or eastward propagation of the metamorphism and magmatism can be clearly identified. In contrast, the new data reveal a progressive propagation of the thermal anomaly from the base to the surface of the continental crust. Focusing on the key localities of the Mauléon basin, Arguenos-Moncaup, Lherz, Boucheville and the Bas-Agly, we analyze the thermal conditions prevailing during the Cretaceous crustal thinning. The results are synthetized into a series of three regional thematic maps and into two detailed maps of the Arguenos-Moncaup and Lherz areas. The results indicate a first-order control of the thermal gradient by the intensity of crustal thinning. The highest grades of metamorphism are intimately associated with the areas where subcontinental mantle rocks have been unroofed or exhumed.

“…The present study only focuses on dolomitisation events in the host limestone, since the early limestone diagenesis has been described in detail by Lopéz-Horgue et al (2009 and and Rosales and Pérez-Garcia (2010). Various calcite and dolomite phases were distinguished on the basis of excellent exposures and petrographic studies.…”
