Further evidence for a relatively high sea level during the penultimate interglacial: open-system U-series ages from La Marina (Alicante, East Spain) Goy Goy, José Luis Hillaire-Marcel, Claude Zazo Cardeña , Caridad Bassam, Ghaleb Dabrio González, Cristino José González Ureña, Ángel Bardají Azcárate, Teresa Civis Llovera, Jorge Preda, Michael Yébenes, Alfonso Forte, Alessandro M. The elevation and timing of high sea stands during Oxygen Isotope Stage (OIS) 7 are not as well constraíned as those of OIS 5e. Conflictíng values are reported from Medíterranean coastlines, and fossil dating is inaccurate because of ubiquitous open U-series systems. New morphostratigraphic data from La Marina (eastem Spain) supported by open-system U-series coral ages shed light on the maximum sea level duríng OIS 7. Fossil corals (Cladocora Caespitosa) underlying an OIS 5e marine unít yielded U-series ages from 178 ± (0 to 208 ± 1) ka (± 20σ n=7) with an outlier al 240 ± 18 ka. Mean open-system limit ages of 170 ± 10 (minimum age after correction for 234Th-230Th uptake) and 237 ± 20 ka (maximum ase after correction for 238U - 234U uptake) were calculated to have a probable age closer to the minimum value, for an assignment of OlS 7a or 7c. The occurrence of a warn-water "Senegalese" fauna (Strombus bubonius) in OIS5e and OIS 7 marine units confirms the arrival of tropical species to the Mediterranean before the last interglacial periodo Morpho-sedimentological and neotectonic studies suggest that the maximum paleo-sea level during OIS 7c or 7a was a few melers below that of OlS Se. 2023-06-20T09:24:37Z 2023-06-20T09:24:37Z 2023-06-20T09:24:37Z 2006 journal article https://hdl.handle.net/20.500.14352/49387 0985-3111 10.3166/ga.19.409-426 eng open access Lavoisier (Hermes Science Publications)
