A tectono-stratigraphic analysis of a broadband 3D seismic survey over the outer slope of Côte d'Ivoire margin, west Africa, revealed that Cenomanian and younger strata seal well-developed rift fault blocks up to 15 km across. Growth strata indicate that these were formed during rifting that culminated in seafloor spreading in the late Albian, challenging existing plate reconstructions for the opening of the equatorial Atlantic ocean. A previously unrecognized system of volcanic edifices linked at depth to a network of sill complexes has also been identified. These are aligned along a NE–SW trend, concordant with kilometre-wide ridges, interpreted as folds formed by steep, crustal faults with an oblique-slip component. These trends are similar to those of fracture zones in the region and indicate that the Côte d'Ivoire was a transform margin in the late Albian. These results highlight the potential of offshore Côte d'Ivoire for deep-water rift plays with large traps formed by extensional fault blocks together with prospective Albian reservoirs ponded in their hanging walls. In addition, the volcanoes and ridges generated seabed relief along the newly created transform margin, forming confined basins for potential deposition of Turonian and younger turbidites and the generation of stratigraphic traps.

The communication relates the experience of a Workshop held at the Patio Herreriano Museum of Spanish Contemporary Art in Valladolid, on the occasion of the celebration of World Architecture Day, in 2019. Through a collaborative practice between teachers, architects, artists and students, a series of temporary installations were executed to accompany an exhibition under the motto "Valladolid Efímera". Participation was open to students and professionals related to the matery and took place outside specifically academic programs. The objective was to exploit the possibilities of an auxiliary element for construction, such as scaffolding, to generate playful spaces, investigating its ability to interact with an existing architecture and highlight its ceremonial character. In the process to carry it out, different learning methodologies have been involved that have shown how ephemeral architecture can be considered an effective pedagogical tool. La comunicación relata la experiencia de un Workshop realizado en el Museo de Arte Contemporáneo Patio Herreriano de Valladolid, con motivo de la celebración del Día Mundial de la Arquitectura, en el año 2019. A través de una práctica colaborativa entre profesores, arquitectos, artistas y alumnos, se ejecutó una serie de instalaciones temporales, para acompañar una exposición bajo el lema “Valladolid Efímera”. La participación era abierta a estudiantes y profesiones afines a la materia y se desarrollaba fuera de programas específicamente académicos. El objetivo era explotar las posibilidades de un elemento auxiliar para la construcción, como es el andamio, para generar espacios de carácter lúdico, indagando en su capacidad de interacción con una arquitectura existente y resaltar su carácter ceremonial. En el proceso para llevarlo a cabo se han visto implicadas distintas metodologías de aprendizaje que han puesto de manifiesto cómo la arquitectura efímera puede considerarse una eficaz herramienta pedagógica.
