“…Taking into consideration all the above data from Lanzarote and Fuerteventura, the multi-terrace model of Zazo et al (2002), including their I to IX marine terraces, does not appear to be valid. Our conclusions do not apply to the younger (X to XII) marine terraces of Zazo et al (2002), of Late Quaternary age deposits that have been studied more recently (Meco et al, 2018;Montesinos et al, 2014;Muhs et al, 2014).…”

The Canary Islands offer an outstanding context for paleoclimatic studies because their volcanic nature and the presence of datable lava flows, their antiquity, the existence of marine deposits and their location in the NE Atlantic. New records of Miocene and Pliocene coastal deposits are registered in the eastern Canary Islands, 100 km off the NW African coast. Late Miocene marine deposits are conglomerates and sandstones assigned to the Tortonian through a new 40 Ar/ 39 Ar age (9.60 ± 0.05 Ma) of an overlying lava flow at the Janubio site in Lanzarote Island. These deposits contain littoral-intertidal and intertropical genera of fossils, e.g. the gastropod Nerita and the coral Siderastrea, they are almost horizontal and were elevated up to 36 m in height by regional or local tectonics, yielding a relatively low rate of uplift of~3.75 m/Ma. Furthermore, Early Pliocene coastal deposits studied, are mainly marine conglomerates and sandstones and derived aeolianites that are spread over the south of Lanzarote and the west of the Jandía peninsula of Fuerteventura Island. No associated lava flow permits their dating, but they contain marine fossils of littoral and intertropical genera, as the gastropods Nerita and Persististrombus and the coral Siderastrea. They are all inclined toward the coast in the form of a large layer elevated up to 70 m a.s.l., in a surrounding geological environment with gypsum and aeolianites that indicate a eustatic sea-level fall with a regressive effect in the area. These deposits, previously attributed to the Quaternary, are now assigned to the Zanclean because of its similarity in lithology, appearance and fossil content with deposits in western Fuerteventura and NE Gran Canaria. The nearby existence of paleosols with particular structures indicates the start of climatic seasonality in the region; and the only possible time interval in a global context (record of deep-sea oxygen isotopes and sea-level history) fits in the most notable Pliocene global climatic change (~4 Ma) that is registered in the Canary Islands by mean of these coastal and aeolian deposits.

“…LIG marine deposits are found in the Eastern Canary Islands. In Lanzarote, these deposits have outcrops mainly at the localities of La Santa, Matagorda and Punta Penedo (Meco et al, 2006;Muhs et al, 2014), whereas in Fuerteventura they occur at the localities of Matas Blancas, Las Playitas and La Guirra (Meco et al, 2002;Zazo et al, 2002;Meco et al, 2006;Montesinos et al, 2014;Meco et al, 2018) (Figure 1b). LIG marine deposits also occur in the central island of the archipelago in Las Palmas, Gran Canaria (Meco et al, 2002).…”

“…(3) Over the last decades, the geology, sedimentology and chronology of the Canary Islands have been thoroughly investigated, as well as the composition of faunal taxa found in the marine fossil deposits and in paleosols (Meco and Stearns, 1981 ;Meco et al, 2002 ;Zazo et al, 2002 ;Meco et al, 2006 ;Meco et al, 2011 ;Muhs et al, 2014 ;Montesinos et al, 2014 ;Meco et al, 2018). This rich source of information is relevant to establishing the chronology of the deposits under study.…”

“…Así, con el cierre de América central, la Corriente del Golfo se intensifica, empiezan a cumularse hielos en el Polo Norte, se enfría la Corriente de Canarias, baja el nivel del mar y las arenas marinas quedan al descubierto y son acumuladas en forma de dunas en Fuerteventura donde quedan sepultadas por una lava datada en unos 3 Ma. Y, lo más reciente, los depósitos de playa (Figura 9) datados por Carbono catorce en unos 1.500 años (Meco et al, 2018) que corresponderían a un grado de precesión de los equinoccios. Finalmente, en la actualidad estamos trabajando en la relación, posiblemente visible en Canarias, entre los depósitos marinos cuaternarios y el origen de la Tierra actual y la Luna.…”

La comunidad universitaria de la ULPGC, y en particular la de su Facultad de Ciencias de la Educación, rinde con La investigación acompañando a la vida Estudios en Homenaje a Emigdia Repetto Jiménez un tributo a la excepcional trayectoria docente e investigadora de doña Emigdia Repetto Jiménez (1935-2020). Estas páginas quieren ser una miscelánea en recuerdo de las múltiples dimensiones profesionales que jalonaron el discurrir de la homenajeada, desde su trayectoria docente en diferentes etapas, modalidades y ámbitos educativos, hasta su prolija mentoría en investigación, sin dejar atrás su inestimable legado en la gestión académica o su liderazgo didáctico en la creación de materiales. En definitiva, muestra un reconocimiento a la pasión de Emy por la difusión de la cultura científica.
