Detailed mapping of the Jurassic to pre-Albian deposits of central and eastern Asturias (NW of the Iberian Peninsula) allowed several Upper Jurassic and Lower Cretaceous outcrops, previously assigned to other ages, to be identified. Where possible, these outcrops were correlated with the well-known sequences outcropping on the Asturian coast. A new Jurassic stratigraphic unit, the Miyares Formation, was defined, consisting of a conglomerate Lower Unit, a Middle Unit composed mainly of oolitic limestones and an Upper Unit comprising bioclastic and marly limestones with a rich larger foraminiferal fauna. The Lower Unit is interpreted as deposited in a fan delta, the Middle Unit represents a shallow marine high-energy environment, and the Upper Unit deposited on a restricted shallow marine platform. The shallow-water foraminiferal assemblage from the Upper Unit is attributed to the Tithonian and the oldest Cretaceous rocks are Barremian. Therefore, there is a stratigraphic gap recorded in the study area, which might correspond to the latest Jurassic to Early Cretaceous pro parte timespan.Keywords: Late Jurassic, Early Cretaceous, Larger Foraminifera, NW Spain Resumen Una cartografía geológica detallada de los depósitos jurásicos y cretácicos pre-albienses ha permitido identificar varios afloramientos del Jurásico Superior y del Cretácico Inferior, asignados previamente a otras edades. Donde ha sido posible, estos afloramientos han sido correlacionados con las sucesiones bien conocidas que afloran en la costa asturiana. Se ha definido una nueva unidad, la Formación Miyares, formada por una Unidad Inferior conglomerática, una Unidad Media mayoritariamente de calizas oolíticas y una Unidad Superior de calizas bioclásticas y margosas con abundantes macroforaminíferos. La Unidad Inferior se interpreta como depósitos de fan delta, la Unidad Media representa un ambiente marino somero de alta energía, y la Unidad Superior fue depositada en una plataforma marina somera restringida. El conjunto de foraminíferos de agua somera de la Unidad Superior se atribuye al Titoniense y las rocas más antiguas del Cretácico son del Barremiense; existe por lo tanto, en el área de estudio, una laguna estratigráfica que abarca la parte terminal del Jurásico y una parte del Cretácico Inferior.

Background: The past few years have witnessed an increase in the availability of food products containing one or more low- and no-calorie sweeteners (LNCS) in the Spanish market, mostly due to the new massive reformulation plan. However, these are not included in food composition tables or databases, and, therefore, assessment of their intake among the population is complex. This study aims to update a database including commercialized foods and beverages.Method: A systematic search of ingredients information from the different food and beverage categories was undertaken during 2019 by recording the availability and type of LNCS declared in the information of the product from labels and online shopping platforms of retailers from Spain to update a previous food composition database compiled in 2017.Results: A total of 1,238 products were identified. The major groups were sugar and sweets (24%), non-alcoholic beverages (21%), cereals and grains (19%), and milk and dairy products (14%) accounting for >70% of total products. The mainly declared LNCS were sorbitol (19.5%), sucralose (19.5%), and acesulfame K (19.2%).Conclusion: There is a wide variety of products that include LNCS as a main ingredient with higher availability than when compared with the results of database of 2017, consequently, it might be expected that LNCS are commonly consumed at present in the Spanish diet.
