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 ...

Chemische Gärten sind selbstorganisierte abiotische Strukturen mit „lebensähnlichen” Formen. Hier zeigen wir, dass solche Prozesse auch nach Zugabe konzentrierter Sulfatlösungen zu festen Calciumsalzen ablaufen und sogenannte Gipsgärten ergeben. Die dafür nötigen Bedingungen sind weitgehend kompatibel mit den geochemischen Verhältnissen auf dem frühen ...

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

Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

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 ...
