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. [...]

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. [...]

Ibuot, Johnson C. (University of Nigeria)
Seismic refraction methods are vital in geophysical investigations to reveal subsurface geological structures. This study focuses on the Ini Local Government Area, Akwa Ibom State, Nigeria, analyzing geological features beneath the surface, with emphasis on seismic velocities and layer thicknesses. [...]
