Complementary data of the Quaternary Map of Spain: active faults, extent of glaciations and key sites

20th Congress of the International Union for Quaternary Research (INQUA). Dublin, 25th and 31st July 2019, AbstractThe basic information of geological maps about formations sometimes needs other kind of complementary data that helps to inform about significant subjects such as the relationship between the formations and the internal and external geodynamic, to indicate geological materials that cannot be represented with their real dimension at the map scale, but singular, or to highlight remarkable sites of special science interest. As a general rule, the usefulness of complementary data will increase as the scale of the map decreases and as the geological complexity and diversity of the territory rises. Adding information about active faults to the Quaternary Map of Spain is not a simple cosmetic exercise. In the SE of Spain there is a set of small intermountain sedimentary basins originated during the upper Miocene (Tortonian) with continuous deposition until the Pleistocene (basins of Granada, Guadix - Baza, etc.) and related to sets of faults of the Betic orogen (Iberian – Africa plate boundary). Therefore, the Quaternary-Active Fault Database of Iberia or QAFI is an important source of complementary data for the Quaternary Map of Spain and helps to understand these tectonic relations (Figure 1). The QAFI is an inventory of faults showing evidence of activity during the Quaternary. The QAFI is a project created, supported and periodically updated on the basis of the available scientific literature by the Instituto Geológico y Minero de España (IGME, Spain) and the Laboratório Nacional de Energia e Geologia (LNEG, Portugal). To catalogue geosites of interest has been a usual task of the IGME in recent decades. The IGME, in collaboration with experts from other scientific institutions, has also developed the "Global Geosite Project” (IUGS - UNESCO) in Spain, result of which was the selection of 20 geological frameworks of international significance for conservation. One of these frameworks is named “Vertebrate deposits of the Spanish Pliocene and Pleistocene” and it includes 20 selected paleontological sites, most of them in karstic environments, spread out from the north (Cantabrian Mountains and Pyrinees) to the south (Betic range), with a great faunal diversity and an almost a continuous record of the Quaternary (Figure 2). These deposits are the minimum of key sites that should be indicated in the maps of the Quaternary of Spain and in the European one. Quaternary glaciers of the Spanish mountains were small and scattered, except in Piryenees. and their moraines are impossible to represent at the map scale. Therefore, the limits of the last glacial maximum is an important dataset for the Quaternary Map of Spain and the only way to show these glaciated areas.Instituto Geológico y Minero de España, EspañaGeolag, Españ
