Alçiçek, Mehmet Cihat (Pamukkale University (Turquia))
A multiproxy study of the Lower Pliocene (Zanclean) shallow lacustrine succession in the southwestern margin of the Baklan Basin (SW Anatolia, Turkey) provides new insights into the paleoclimatic, paleohydrologic, and paleovegetation evolution of an extensional basin located at the top of the western Taurides mountain range in the southeastern Mediterranean region.

Bioreduction of Fe-oxides in mine tailings deposited under marine conditions releases Fe and associated trace elements (e. g. , Ti, Ni, Cd, Pb), leading to contamination of the marine environment. Sea-tailings disposal (STD) along the northern coast of Chile (Ensenada Chapaco) and along the eastern coast of Spain (Portman Bay) results in an adverse impact on the environment. [...]

Continuous core recovery, core scanning and physical property logging for characterization and petrophysics analyses in the Chicxulub drilling projects are reviewed. We focus on the Yaxcopoil-1 borehole, one of the Chicxulub boreholes drilled in the terrace zone that sampled the post-impact carbonates, impact breccias and target Cretaceous carbonates. [...]

The precise determination of the tectonic deformation timing such as thrust emplacement has always been a challenge for understanding the evolution of fold-and-thrust belts. In the Catalan Coastal Ranges, this issue has traditionally been addressed through the mapping and the analysis of the syn-tectonic successions preserved in the SE margin of the Ebro Basin. [...]

Latest Barremian - early Aptian chronostratigraphy and sedimentary evolution of the northwestern Maestrat Basin

Moreno Bedmar, Josep Anton (Universidad Nacional Autónoma de México) ;
Calvin, Pablo (Instituto Geológico y Minero de España de España) ;
Aurell, Marcos (Universidad Zaragoza)
Some aspects on the age and correlation of the upper Barremian-lower Aptian stratigraphic units of the NW Maestrat Basin were uncertain prior to this study, due to the differing lithostratigraphy of the marginal Oliete subbasin compared to the more depocentral Galve and Morella subbasins. [...]

New spider crabs (Brachyura, Majoidea) from the early Eocene of Spain with a reassignment of the species "Periacanthus" tetracornis
/
Ferratges, Fernando Ari (Instituto Geológico y Minero de España)
Spider crabs (superfamily Majoidea Samouelle, 1819) represent a highly diverse group within Eubrachyura de Saint Laurent, 1980. This study re-examines the species "Periacanthus" tetracornis Ferratges, Ortega Fernández, Moreno and Maza, 2014 (Roda Formation, lower Eocene of Spain) which was previously consider as a member of Epialtidae MacLeay, 1838 and it is included as a new genus of majoid crabs, Eoactinotocarcinu n.

The middle-upper Campanian Allueva Formation is located in the continental Montalbán subbasin (NE Spain) at the onset of the Alpine compression. This formation consists of alluvial terrigenous sediments, but it is locally dominated by carbonates and microbialites, which are the main focus of this study. [...]
