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.

21 p, 1.1 MB Fracture-related dolostones replacing Upper Jurassic-lowermost Cretaceous syn-rift deposits in the eastern Iberian Chain (eastern Spain) / Travé i Herrero, Anna (Universitat de Barcelona) ; Salas, Ramon (Universitat de Barcelona) ; Cantarero, Irene (Universitat de Barcelona) ; Baqués, Vinyet (Universitat de Barcelona) ; Cruset, David (Geociències Barcelona) ; Gomez-Rivas, Enrique (Universitat de Barcelona) ; Martín-Martín, Juan Diego (Universitat de Barcelona)
Upper Jurassic and Lower Cretaceous limestones and dolostones serve as hydrocarbon reservoirs in the offshore area of NE Spain. Since similar dolomitized rocks crop out in the adjacent onshore Maestrat Basin in the SE Iberian Range, understanding the dolomitization and other diagenetic processes is key to assessing reservoir properties. [...]

21 p, 22.7 MB Strontium-isotope stratigraphy of the Aptian-Albian transition in the western Maestrat Basin (E Iberia) / Bover-Arnal, Telm (Universitat de Barcelona) ; Moreno Bedmar, Josep Anton (Universidad Nacional Autónoma de México) ; Salas, Ramon (Universitat de Barcelona) ; Pascual-Cebrian, Enric (Universitat de Barcelona)
The Aptian-Albian transition in the Maestrat Basin (E Iberian Chain) encompasses two lithostratigraphic units: Benassal and Escucha. In some sectors of the basin, such as the western Galve and Las Parras sub-basins, this stratigraphic interval recorded a progressive shift from widespread carbonate platform settings to coastal siliciclastic-influenced and coal-bearing environments. [...]

Trace element contents in bornite, chalcopyrite and pyrite (LA-ICP-MS) from Miocene porphyry copper-gold deposits from Metaliferi Mountains, Romania / Calugaru, Mihaela-Elena (Institutul Geologic al României (Romania)) ; Munteanu, Marian (Institutul Geologic al României (Romania))
In porphyry systems, valuable elements such as Au, Ag, Te, Se and Bi are found in trace contents associated with Cu and Fe sulfides. The relations between sulfide and the trace element contents, as well as the role of physicochemical factors in the uptake of different trace elements are still being assessed. [...]

11 p, 2.3 MB Grain-size reduction reduces the impact of viscous shear heating in lithospheric mantle shear zones / Ruh, Jonas B. (Instituto de Ciencias del Mar - CSIC)
Active plate tectonics require weak boundaries that accommodate large strain over long time periods. Many studies argue that shear heating converted from dissipated mechanical energy may be responsible for the necessary weakening in the mantle lithosphere to initiate and sustain weak plate boundaries. [...]

The collision between the Arabian and Eurasian plates resulted in the uplift of The East Anatolian Province of Shortening (EAPS). Within the EAPS, the faulting mechanism is characterized by right- and left-lateral strike-slip faults, thrust faults, and a relatively limited occurrence of normal faults. [...]

26 p, 17.1 MB Shortening-controlled magnetic fabrics in the Alpine thrust front of the Cantabrian Mountains / Oliva-Urcia, Belén (Universidad de Zaragoza) ; Román-Berdiel, Teresa (Universidad de Zaragoza) ; Torres-López, Sara (Universidad Autónoma de Madrid) ; Villalaín, Juan J. (Universidad de Burgos) ; Casas-Sainz, Antonio (Universidad de Zaragoza)
The magnetic fabrics (or anisotropy of magnetic susceptibility) are used in this work to decipher thrust kinematics in the Cantabrian (western) Pyrenees. Most of the analyzed rocks (total of 51 sites) correspond to the Mesozoic rifting and post-rifting stages (Triassic, Jurassic and Cretaceous) rocks in the Asturian-Leonese region, whose alpine structure is controlled by south-verging, basement-involved thrusts.

(Institute of Geophysics (República Txeca)) ; Kučeráková, Monika (Czech Technical University (República Txeca)) ; Vratislav, Stanislav (Czech Technical University (República Txeca))
This research investigates microstructures and crystallographic preferred orientation in a high-temperature Variscan small-scale shear zone within marbles from the south-western Ossa-Morena Zone (Iberian Variscan Belt). [...]

18 p, 12.2 MB Basement structural controls on the Jurassic sedimentary sequences in the Tampico-Misantla basin, Northeastern Mexico from a 3-D seismic reflection study / Canales-Garcia, Iza (Universidad Nacional Autónoma de México) ; Pérez-Cruz, Guillermo (Universidad Nacional Autónoma de México) ; Urrutia-Fucugauchi, Jaime (Universidad Nacional Autónoma de México) ; Luna-Gomez, Victor (Universidad Nacional Autónoma de México)
The Tampico-Misantla basin is a mature oil rich province in northeastern Mexico with large unconventional oil plays currently being revitalized. Results of a 3-D seismic reflection study of the basement and Jurassic sequences are used to analyze the basement influence on sediment sequence and basin structure, by mapping the seismo-stratigraphic horizons for the (Tithonian) Pimienta, (Kimmeridigian) Taman/San Andrés, (Oxfordian) Santiago, (Callovian) Tepexic/Huehuetepec and (Bathonian) Cahuasas formations.

Departament de Dinàmica de la Terra i de l'Oceà) ; González, Lenin (Universidad Central de Venezuela) ; Esteban, Mateu (Universitat de Barcelona) ; Salas, Ramon
Based on field data collected in the northern and southern Falcón Basin (Venezuela), this paper presents a comprehensive monograph that reports on the age and sedimentary evolution of the San Luis and Churuguara formations. [...]

The Precambrian tectonic evolution and growth of continental crust in the southern part of North Odisha Singhbhum Craton discusses the possible petrogenetic process and source characteristics.
