AB In the central part of the Cameros basin (NW Iberian Chain) has been analysed the orientation of calcite c-axes and e-twin from the sparitic grains that filled extension veins in this region. The c-axls orientations allow to establish that during the mesozoic extensional episode, when was developed this basin, besides of an extension NE-SW also existed another with a NNW-SSE trend, this last extension direction probably has a regional character.The calcite e-twins show the existence of two different orientations for strain ellipsoids. A first group has orientations that would be compatible with structures associated with the development of the basin inversion and with the NE-SW schistosity. While the other is almost perpendicular to the former and it is compatible with a NW-SE compression not described until the moment. This last deformation episode probably has a regional meaning (Cuadarrama compression? from Capote et al., 1990), and it likely also has a relative importance in the development of structures that show this region
