“…The international and national relevance of the geosites has been proposed because of the existence of bibliographic references and research projects. The sites include: Miera glacier valley [17,27,35,[37][38][39][40][41][42][43][44]; iron mineralisation in Peña Cabarga Paleokarst (included in the Global Geosites Project); the Matienzo polje [32,[45][46][47]; the Mortillano hydrogeological system [18,22,[48][49][50][51][52]; the Liendo diapir [31,32]; the Sonabia dunes [26,32,42,53,54]; the Asón estuary [24,[55][56][57][58][59][60][61][62][63][64], and the Covalanas cave, a UNESCO World Heritage Site since 2008 [64][65][66].…”

UNESCO-designated geoparks, intended for conservation, seek to drive economic development via geological heritage education and tourism. Since 2018, within the framework of the European project Atlantic Geoparks (Interreg Atlantic area program), the Valleys of Cantabria project has been promoted to declare a UNESCO Global Geopark (UGGp) in the Cantabria region (northern Spain). The Valles de Cantabria proposal, aligning with UNESCO objectives, evaluates the region’s geopark potential, emphasizing sustainable development and societal education. Covering 600 km2 in eastern Cantabria, the territory involves 19 municipalities and has a population of 60,600. The geological context, ranging from the Triassic to the Quaternary periods, reflects the complex evolution of this territory, which has been influenced by tectonic forces, geomorphological processes, and sea-level changes. Detailed reviews and fieldwork performed by experts, including university researchers, have identified 66 sites of geological interest (SGI). The geosites, which have different geological–geomorphological significances, have been assessed according to their scientific value (including educational importance), potential of use (mainly geotouristic use), and vulnerability or risk of degradation. The geological heritage is directly related to the high biodiversity of the area. The challenges of this territory, such as depopulation and the low income of the inhabitants, can be improved with the declaration of a geopark, which would help to create new job opportunities related to geotourism and sustainable development. UNESCO recognition could catalyse scientific research, address socioeconomic challenges, and foster rural revitalization, strengthening the symbiotic relationship between geoconservation and local economic growth. Collaboration with other Atlantic geoparks has enabled the exchange of experiences that will hopefully deepen in the future. Consequently, the aim of this work is to explore the potential of this territory in terms of high-quality geological features and biological and cultural heritage, as well as to evaluate the socioeconomic context that makes the territory potentially suitable for promoting a UGGp.

Dynamics and sedimentary assessment of a rock-bounded estuary: a case study—Tina Mayor (NW Spain, Iberian Peninsula)

2022

Based on a comprehensive study of the Tina Mayor estuary, a conceptual morphosedimentary model is proposed for one of the best-preserved limestone sectors of the Iberian Peninsula. This mesotidal and rock-bounded estuary consists of a significant proportion of quartzitic gravel fractions, which is distinctive compared to the other nearby estuaries of Northwest Spain on the Iberian Peninsula. Fluvial discharges allow for high coarse fraction inputs to be distributed to all the geomorphological estuarine zones, particularly the mouth, the bay and the inner areas. Moreover, the narrowing of the rocky boundary affects the outermost sector of the mouth of the estuary, developing two coarse grain spits; the inner being much more extensive, while tidal flats occupy a greater reclaimed area than the natural ones. The dominant sedimentary flow regime was established based on tidal and current records during a tidal cycle. The flood currents crossing the bay change trajectory at the mouth boundary as a result of rocky narrowing from the western mouth to the eastern inner side in a reverse response to the Coriolis effect. Estuarine morphosedimentary units are mapped, including the large and minor bedforms in each estuarine zone. These have been characterised according to the average values of the granulometric parameters (coarsest 1-percentile grain size or centile, mean size, sorting, skewness and kurtosis), as well as the carbonate (bioclast) percentage, including the trend maps of the mean size, sorting and biogenic carbonate content. Furthermore, taking into account the mean tidal amplitude and mixing waters (QF/QT), a suitable classification can be established for any type of estuary, including the characteristics of the confinement of the estuary mouth.
