| This basin is emphasized by normal fault scarps that face the river from its SW bank. |
| The current morphology of the coastal terraces suggests that oblique-slip thrust movements have recently exceeded oblique-slip normal fault movements. |
| We interpret this pattern as a Mesozoic normal fault zone whose inversion gave rise, along strike to the NW, to the south Cameros thrust. |
| Massive dolomite and dolomitic breccias are separated by a normal fault from the upper part of the sequence. |
| It is now commonly accepted that the dip of the steeper part of a listric normal fault is approximately 60 deg. |
| As there is no sign of contact metamorphism in the limestones, we interpret this to be a normal fault. |
