This peculiar polymict breccia uniformly exposed\u00a0 at the base of the unfolded Upper Tertiary over a distance of at least 120 km is a strong clue to the Mid-Tertiary\u00a0multiple impact\u00a0<\/a>in northern Spain. A lot has already been said and written about this breccia (Ernstson & Fiebag, 1992; Ernstson & Claudin 2002, Ernstson et al. 2003; Claudin & Ernstson 2003;\u00a0http:\/\/www.impact-structures.com\/impact-rocks-impactites\/the-suevite-page\/suevites-from-the-azuara-and-rubielos-de-la-cerida-spain-impact-structures\/<\/a>,\u00a0http:\/\/www.impact-structures.com\/impact-spain\/the-rubielos-de-la-cerida-impact-basin\/basal-suevite-breccia-in-the-rubielos-de-la-cerida-impact-basin\/<\/a>), and that is why we confine ourselves to show some new varieties exposed about 2 km northeast of Olalla in the rim zone between the Azuara impact structure and the Rubielos de la C\u00e9rida impact basin. We point to the dominating Paleozoic and Triassic components, to the flow texture, to halos around many clasts, to the remarkable fitting of fragmented clasts, to breccias-within-breccias, and we think that some of the breccias are simply beautiful.<\/p>\n

Here, we want to mention that regional geologists from the Zaragoza university and the Madrid Center of Astrobiology (\u00c1ngel Luis Cort\u00e9s, Marcos Aurell, Enrique Diaz-Mart\u00ednez, and others), which basically deny an impact in that region,\u00a0 consider this typical breccia a lacustrine sediment or\u00a0 even a conglomerate (Aurell et al. 1993; Cort\u00e9s, Nov. 6, 2002, Heraldo de Arag\u00f3n).<\/p>\n<\/div>\n
