N-S-striking geological cross-section (see location on Fig. 1) across the Central Pyrénées from the Axial Zone to the south to the Aquitaine Foreland Basin to the north. (a) Geologic cross-section associated with the distribution of the HT/LP metamorphism and relevant graph (T_max versus distance). The isograds were plotted with a margin of error. (b) Close-up on the Mesozoic basins.
