Geologica Acta
Geologica Acta (ISSN 1695-6133 / ISSN electrónico desde 1696 hasta 5728) es una revista institucional y de acceso abierto, internacional y con un perfil generalista de Ciencias de la Tierra. La revista acoge tanto artículos de tipo conceptual como regional, con especial énfasis en las zonas del Mediterráneo, Sur América y el Caribe, pero sin dejar de considerar contribuciones de cualquier región del mundo. Igualmente se incentiva la publicación de números temáticos que den a conocer los resultados de proyectos o reuniones científicas internacionales.

The study of 13 micromammal localities in the southern section of the Gormaget ravine (Alcoi Basin, SE Spain) and another 4 localities in the northern section has allowed us to define four local biozones in the dawn of the Pliocene, possibly recording the Mio-Pliocene boundary. [...]

11 p, 2.5 MB Late Holocene tectonic implications deduced from tidal notches in Leukas and Meganisi islands (Ionian Sea). / Evelpidou, N. (National and Kapodistrian University of Athens.

(Laboratoire de Géographie Physique (Meudon, França))
In this paper the tectonic behavior of Leukas and Meganisi islands (Ionian Sea) is examined through underwater research carried out in both islands. A possible Late Holocene correlation between coseismic subsidences is attempted and evidenced by submerged tidal notches in both islands. [...]
