“…As a reference section for Global Correlation, the Murtinheira section integrates the recently established Portuguese framework with international relevance "Jurassic record in the Lusitanian Basin" (Brilha et al, 2005;Henriques and Ramalho, 2005). Its classification as a Natural Monument, according to Portuguese legislation on Geoheritage, was ratified in October 2007.…”

The detailed study of benthic foraminifera in 28 samples from Late Toarcian-Aalenian-Early Bajocian hemipelagic sediments of the Murtinheira section (Cabo Mondego, Lusitanian Basin, West Portugal), has permitted the recognition of the assemblage composition and the analysis of their evolution throughout this time interval. The representatives of the Suborder Lagenina dominate all the assemblages and, in the majority of them, the most abundant species is Lenticulina münsteri. The Late Toarcian and Early Aalenian assemblages are very similar. From the Comptum Subzone, a gradual replacement of the Early Jurassic forms by characteristic Middle Jurassic taxa takes place. During the Late Aalenian-Early Bajocian interval, a significant number of last occurrences (LOs) of taxa are recorded. The assemblages composition, the estimation of the relative taxa abundances and the data obtained from the calculation of several diversity indexes, together with the previous sedimentological and paleontological works in this area, indicate that these assemblages were developed in a shelfal basin environment. This platform showed normal marine salinity values, good oxygenation and was always located above calcite compensation depth (CCD). However, the environmental conditions were not always the best for the development of rich and diverse foraminiferal assemblages. These conditions were probably unstable during the Late Toarcian (Aalensis Subzone)-Early Aalenian (lower part of the Comptum Subzone). From the Comptum Subzone to the lower part of the Limitatum Subzone (Late Aalenian), conditions were more stable and more favourable for the development of foraminiferal communities. However, in the Aalenian-Bajocian transition the environmental conditions changed again and affected the development of this group. In the Limitatum Subzone a decrease in the diversity of the assemblages was recorded. This fact seems to be related to a global perturbation in the carbon-cycle that could have affected the foraminifera, together with other marine and continental organism groups.

“…To assess the potential of the mining landforms for the geotourism and geoeducational purposes, the specific procedure should be carried out. The specific steps were discussed in various papers (e.g., Reynard et al, 2007;Reynard et al, 2016;Kubalíková, 2013;Kubalíková & Kirchner, 2016;Pereira et al, 2007;Brilha, 2016Brilha, , 2017Fuertes-Gutierréz & Fernández-Martínez, 2012) and generally, they can be described as follows: 1) inventorying and detailed description of the mining geo(morpho)sites, 2) assessing the geo(morpho)sites (including the SWOT analysis), 3) synthesis (management proposals or conservation measures).…”

Mining Landforms: An Integrated Approach for Assessing the Geotourism and Geoeducational Potential

Anthropogenic landforms (especially the mining landforms – quarries, pits, mines) have undoubtedly a great potential for the geotourism development. In addition, they are important from the geoconservation and geoeducation point of view as they allow to see the Earth-science features that would normally remain hidden (e.g., stratigraphic boundaries or soil profiles). However, the potential of these landforms in some case is not fully recognized and the sites themselves can even be endangered. The article presents guidelines for inventorying and assessment method for geotourism and geoeducational purposes of these specific landforms (respectively, the mining geosites and geomorphosites which are going to be used for geotourism and geoeducation) and gives an example from the area in which geotourism has not been fully developed yet (Červený kopec/Red Hill in Brno, Czech Republic).

“…The majority of the Portuguese protected areas are focused on biological objects rather than geological, resulting on a higher number of protected areas based on bio aspects even though this trend has been facing some changes in recent years (Henriques, 2004). Regardless the vast scientific knowledge concerning the Jurassic relevance of Cape Mondego and the fact that it has been included in the inventory of the Portuguese geological heritage within the framework ''Jurassic record in the Lusitanian Basin'' (Brilha et al, 2005) and also the protection as Natural Monument, no systematic geosites inventory was ever carried out in this protected area.…”
