Jc. Sibuet et al., PLATE BOUNDARIES AND EXTENSION IN THE WES TERN BAY OF BISCAY ASSOCIATED WITH THE PYRENEAN PHASE, Comptes rendus de l'Academie des sciences. Serie 2, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre, 317(9), 1993, pp. 1207-1214
A detailed bathymetric survey carried out in the vicinity of the Bay o
f Biscay fossil triple junction and available multibeam data have been
used to produce a new bathymetric map of the western Bay of Biscay. F
rom these documents, we have clearly identified the Iberia-Europe plat
e boundary which was active during the pyrenean orogenic phase and det
ermined the total extension which occurred between the two plates in t
he western Bay of Biscay.
