The Sierra Bermeja Pluton (∼60 km 2 surface area) exemplifies a type of controversial granites of the Iberian Massif (European Variscan Belt), the cordierite-bearing 'Serie Mixta' (mixed series) monzogranites. The pluton is included almost completely in the Cornalvo Natural Park (Badajoz, Spain), a relevant target area in Roman times. The geological mapping summarised in the presented map at 1:10,000 scale has revealed a complex intrusive assemblage. Three main cordierite-bearing monzogranite types that show local varieties constitute most of the massif. Monzogranite intrusions are younger towards the centre of the pluton and gave rise to outstanding mappable mingling/mixing zones in some areas. A NE-SW trending reduced dyke complex composed by vaugnerite series rocks, lamprophyres, aplites and quartz dykes, completes the lithological assemblage of the pluton. An inventory of Geologic Points of Interest to promote the geological knowledge of this remarkable protected area and its geoconservation is also presented.
A detailed geomorphological map at 1:25,000 scale is presented for the Valdegovía valley (Álava, Northern Spain), located at the central zone of the Basque-Cantabrian Basin. The map has been developed after several field surveys, with the aid of GIS techniques and high resolution digital terrain models (DTM) derived from LiDAR datasets. The high resolution LiDAR DTMs have revealed uncountable ground features and slope breaks that frequently are hidden by dense forests. Considering the tectonic control and the current sub-Mediterranean climate of the studied area, most landforms and deposits in the Valdegovía valley respond to lithostructural, gravitational, karstic, fluvial, and anthropogenic morphogenesis. We conclude that the geomorphological evolution of the Valdegovía valley has been strongly conditioned by a structural control related with two main NW-SE trending asymmetric folds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
