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.

Shore platform and cliff notch transitions along the La Paz Peninsula, southern Baja, Mexico / Trenhaile, Alan S. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences) ; Porter, N.I. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences) ; Prestanski, K. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences)
Increasing exposure to wave action produces a northerly transition from high tidal notches to shore platforms in the andesitic lahar deposits of the La Paz Peninsula, southern Baja, Mexico. Twenty-four notches were surveyed and wear pins were cemented into the apex of each notch. [...]

Characterization of wind-blown sediment transport with height in a highly mobile dune (SW Spain) / Navarro, M. (Universidad de Cádiz. Departamento de Física Aplicada) ; Muñoz-Perez, J.J. (Universidad de Cádiz. Departamento de Física Aplicada) ; Román-Sierra, J. (Universidad de Cádiz. Departamento de Física Aplicada) ; Ruiz-Cañavate, A. (Universidad de Cádiz. Departamento de Física Aplicada) ; Gómez-Pina, G. (Demarcación de Costas Andalucía-Atlántico)
The Valdevaqueros dune is located at one of the windiest points of Europe, where the frequent occurrence ofstrong easterly winds has generated a highly mobile dune. Several rotating cup anemometers in vertical array anda self-designed vertical sand trap, were placed to retain the drift sands at different heights over the surface in orderto determine theoretical and actual sand transport rates in the Valdevaqueros dune system.

Bedform variability and flow regime in a barrier-inlet system : the mesotidal Piedras mouth (Huelva, SW Spain) / Morales, J.A. (Universidad de Huelva. Departamento de Geología) ; Delgado, I. (Universidad de Huelva. Departamento de Geología) ; Gutiérrez Más, José Manuel (Universidad de Cádiz. Departamento de Ciencias de la Tierra)
Bedform fields from the Piedras River mouth (Huelva, SW Spain) have been studied using side-scan sonartechniques, combined with visual scuba-dives, and direct geometric measuring. The dominant flow regime hasbeen determined from the results in these tidal environments, where erosive processes dominate during ebb,transporting sand as a bedload towards the mouth and central sector of the tidal channel.

Recent evolution of the river mouth intertidal zone at the Río San Pedro tidal channel (Cádiz Bay, SW Spain) : controlling factors of geomorphologic and depositional changes / Gutiérrez Más, José Manuel (Universidad de Cádiz. Departmento de Ciencias de la Tierra) ; García-López, S. (Universidad de Cádiz. Departmento de Ciencias de la Tierra)
Sedimentary and photogrammetric analysis of a sector of Cádiz Bay (SW Spain), including the intertidal zone onthe left bank of the Río San Pedro tidal channel, were performed to understand its environmental evolution andthe main factors that controled it. [...]

Dynamics and morpho-sedimentary interactions in the lower mesotidal estuary of Villaviciosa (NW Spain) : A management proposal / Flor, Germán (Universidad de Oviedo. Departamento de Geología) ; Flor-Blanco, Germán (Universidad de Oviedo. Departamento de Geología) ; Rey, J. (Esgemar, S.A. Estudios Geológicos Marinos)
The accumulation of sediment in the mouth of Villaviciosa estuary (NW Spain) is becoming an obstaclefor the safe navigation in this estuary. One sector of its outer inlet is characterised by a broad shoal linkedwith a longshore bar of a beach, whose erosion is causing the silting of this area. [...]

GIS as a tool to detect flat erosional surfaces in coastal areas : a case study in North Spain / Domínguez-Cuesta, M.J. (Universidad de Oviedo. Departmento de Geologia) ; Jiménez-Sanchéz, M. (Universidad de Oviedo. Departmento de Geologia) ; González-Fernández, J.A. (Universidad de Oviedo. Departmento de Geologia) ; Quintana, L. (Universidad de Oviedo. Departmento de Geologia) ; Flor, G. (Universidad de Oviedo. Departmento de Geologia) ; Flor-Blanco, G. (Universidad de Oviedo. Departmento de Geologia)
The delimitation of flat surfaces, such as marine or continental terraces, can be easily done if they are wellpreserved by using classic techniques such as fieldwork and photointerpretation. However, subsequent landscapeerosion can modify their initial morphology, hindering their recognition. [...]

Reply to the comment by Michard et al. on “Evidence of extensional metamorphism associated to Cretaceous rifting of the North-Maghrebian passive margin : The Tanger-Ketama Unit (External Rif, northern Morocco) by Vázquez et al., Geologica Acta 11 (2013), 277-293” / Vázquez, M. (Universidad de Chile. Andean Geothermal Center of Excellence (CEGA)) ; Asebriy, L. (Université Mohammed V. Institut Scientifique) ; Azdimousa, A. (Université Mohammed I.

Departamento de Ciencias de la Tierra) ; Mellini, M. (Università di Siena. Dipartimento di Scienze della Terra) ; González-Lodeiro, F. (Universidad de Granada. Departamento de Geodinámica)
Michard et al. (this issue) commented on certain aspects of the Alpine metamorphism and structural evolution of the Rif belt (Morocco) that were briefly noted in Vázquez et al. (2013). In particular, they criticize our interpretation of an extensional setting during the main metamorphic recrystallization of the Tanger-Ketama Unit that we considered related to slaty cleavage (S1) parallel to the lithological layering generated during the Cretaceous.
