The Iberian System in NE Spain is characterized by a distinctive graben/basin system (Calatayud, Jiloca, Alfambra/Teruel), among others, which has received much attention and discussion in earlier and very recent geological literature. A completely different approach to the formation of this graben/basin system is provided by the impact crater chai...

... the Rubielos de la Cérida basin was defined by an approximately circular uplift of Mesozoic rocks (Fig. 2, 3), surrounded by a semi-circular to elliptical depression of Quaternary and post-impact Neogene deposits ( Fig. 4; simplified and modified from the geological maps 1: 200.000 ;ITGE, 1991;IGME, 1986). This circular uplift with rocks of the Muschelkalk Fm. in the very center at the village of Rubielos de la Cérida and tectonically very ...

... and the maps 1 : 50 000, sheets Monreal del Campo (IGME 1983) and Santa Eulalia (IGME 1959). Because of its exotic stratigraphic position, the Upper Malmian (Kimmeridgian) block (C) must be considered as a dislocated megablock or assigned to downward "elevator" tectonics over enormous drop. The layer dip has been copied from the 1 : 50 000 maps. Fig. 13. Geological profile (see Fig. 12) of the uplift. The sketched dip of the units refers to Fig. ...

... can be seen in Fig. 11, the unusual topographical situation of the structure can already be seen in the DTM, which will also be discussed later. Fig. 12 shows a highly simplified geological map for the rectangle with a restriction to an indexing of the Mesozoic units. For the white profile line Fig. 13 shows a corresponding section with the corresponding legend. In principle the structural situation is roughly half of the circular central uplift of Rubielos de la Cérida (Fig. 4). The impossibility of a Jiloca graben in its previous interpretation in this area cannot be better characterized than by this stratigraphically and ...

Abstract. - We present a new compilation of previously abundantly studied and published shock effects in minerals and rocks of the Middle Tertiary Rubielos de la Cérida Impact Basin in northeastern Spain. Typologically, we organize by: shock melt - accretionary lapilli - diaplectic glass - planar deformation features (PDF) - deformation lamellae in quartz - isotropic twins in feldspar - kink banding in mica and quartz - micro-twinning in calcite - shock spallation. Included are the newly associated Jiloca-Singra impact in the so-called Jiloca graben and the Torrecilla ring structure, which immediately adjoins the Rubielos de la Cérida basin to the northeast. The compilation and presentation also opposes once more the still existing fundamental rejection of an impact genesis of the Azuara impact event by leading impact researchers of the so-called impact community and by regional geologists from the University of Zaragoza.
We use Schmieder and Kring's article to show how science still works within the so-called "impact community" and how scienti c data are manipulated and "rubber-stamped" by reviewers (here, e.g., C. Koeberl and G. Osinski). We accuse the authors of continuing to list the Azuara and Rubielos de la Cérida impact structures and one of the world's most prominent ejecta occurrences of the Pelarda Fm. in Spain 1 2 as non-existent in the compilation. The same applies to the spectacular Chiemgau impact in Germany, which has been proven by all impact criteria for several years. For the authors' dating list, we propose that the multiple impact of Azuara is included together with the crater chain of the Rubielos de la Cérida impact basin as a dated candidate for the third, so far undated impact markers in the Massignano outcrop in Italy.
