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...

... of the central uplift chain right through the middle of the Jiloca graben, as it has always been interpreted so far, becomes evident. Apart from the geologically fundamentally alien stratigraphic elevations in the middle of the graben, this insight is made possible above all by the high-resolution DTM (Fig. 15) and aerial imagery (Google Earth, Fig. 16) , which clearly show impact-related features. small image inset, Fig. 17 shows the profiles of the terrain elevations taken from the Google map. The topographical peculiarities should not be overstressed here, especially since the geological maps give practically no better stratigraphic itemization of a transpression at the crater ...

... shows the profiles of the terrain elevations taken from the Google map. The topographical peculiarities should not be overstressed here, especially since the geological maps give practically no better stratigraphic itemization of a transpression at the crater rim, but the conspicuous correspondence of the peculiar structures exactly in this area (Figs. 16, 17) strongly supports the reality of this Singra-Jiloca complex impact structure as a lateral companion to the main impact chain extending between the Rubielos de la Cérida uplift and Teruel. For the time being, questions remain unanswered regarding the extension of the SingraJiloca structure in the form of the inner ring to the north ...

... a lateral companion to the main impact chain extending between the Rubielos de la Cérida uplift and Teruel. For the time being, questions remain unanswered regarding the extension of the SingraJiloca structure in the form of the inner ring to the north (Figs. 15, 16) and a certain topographic west-east asymmetry at the edge of the Sierra Palomera (Figs. 16). From the point of view of a complex impact cratering, the formation of the central mountain chain with primary compression and subsequent partial collapse and laterally strong pressure to the outside - here especially in the area of the Palomera uplift - cannot have remained without influence on the more or less simultaneous formation ...

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.
