Shatter cones from the Rubielos de la Cérida impact structure (Spain)

Although in the Rubielos de la Cérida structure competent rocks are widespread and especially exposed in the central uplift, only very few shatter cones have been found so far. This is believed to be mainly due to limited outcrop conditions (freshly exposed rocks are rare) and to the lack of a detailed mapping.
