Estructura y organización de las coladas submarinas: características de las lavas almohadilladas de edad cretácica que afloran en la Cordillera Vasco- Cantábrica

Estudios Geologicos, 1999
Durante el Cretácico superior se desarrolló en la Cuenca Vasco-Cantábrica una importante actividad volcánica submarina de naturaleza alcalina. Este vulcanismo estuvo relacionado con el funcionamiento de un rift y/o una falla transformante en corteza ...

Anatomy of the maxillary canal of Riograndia guaibensis (Cynodontia, Probainognathia)—A prozostrodont from the Late Triassic of southern Brazil

The Anatomical Record, Volume 308, Issue 3, Page 827-843, March 2025.
Abstract Investigating the evolutionary trajectory of synapsid sensory and cephalic systems is pivotal for understanding the emergence and diversification of mammals. Recent studies using CT‐scanning to analyze the rostral foramina and maxillary canals morphology in fossilized specimens of probainognathian cynodonts have contributed to clarifying the ...

Evaluation of bricks durability using destructive and nondestructive methods (DT and NDT)

Materiales de Construccion, 2003
We have studied the physical-mechanical behaviour of solid bricks treated with consolidants and/or water-repellents in accelerated aging tests to determine their durability.

Late Cambrian Syn‐Intrusive Thickening of the Ikh Mongol Arc Domains in the Mongolian Collage

Tectonics, Volume 44, Issue 1, January 2025.
Abstract Structural analysis, U–Pb monazite and xenotime dating, Ar–Ar dating of biotite and amphibole and thermodynamic modeling of peak metamorphic assemblages allow constraining the tectono‐thermal evolution of the migmatite‐magmatite domain on the southern periphery of Precambrian Zavkhan Block. The main subvertical metamorphic fabric resulted from

Tidal versus fluvial point bars: Key features from the integration of outcrop, core and wireline log information of Triassic examples

The Depositional Record, Volume 10, Issue 5, Page 793-820, November 2024.
Abstract The Triassic red beds of the Tabular Cover of the Iberian Meseta are an excellent reservoir outcrop analogue, a direct consequence of high‐quality exposures, which offer exceptional three‐dimensional outcrops, as well as a wide variability of depositional environments.

STRATIGRAPHY AND DIAGENESIS OF THE THAMAMA‐B RESERVOIR ZONE AND ITS SURROUNDING DENSE ZONES IN ABU DHABI OILFIELDS AND EQUIVALENT OMAN OUTCROPS

Journal of Petroleum Geology, Volume 47, Issue 4, Page 395-430, October 2024.
We review published studies characterizing the Thamama‐B reservoir zone in the upper Kharaib Formation (late Barremian) in Abu Dhabi oilfields and at outcrops in Oman. Available data for oxygen and carbon isotope compositions, fluid inclusion measurements, cement abundance and formation water composition are interpreted in terms of a paragenetic model ...

Carboniferous Barrovian to Permian Buchan‐type metamorphic cycles in the Mongolian Altai Zone: Implication for pressure cycles in accretionary orogens

Journal of Metamorphic Geology, Volume 42, Issue 7, Page 979-1033, September 2024.
Abstract In the Altai Accretionary Wedge, several periods of Barrovian‐ and Buchan‐type metamorphic cycles were dated from Ordovician to Permian. However, the timing and link between these cycles are not clear, and their causes are debated. In order to contribute to the understanding of Barrovian‐ to Buchan‐type evolution of the accretionary wedges, we
