“…We also found geoheritage assessments strongly influenced by ideas of magnitude in zones of plutonic intrusions and intracratonic regions (e.g. Fernández et al, 2014;Datta, 2020;Migon and Maia, 2020;Naimi and Cherif, 2021). The inventories describe excellent examples of tors, composed of a series of huge stacked granite outcrops in Mama Bhagne Pahar (India); prominent examples of different geomorphological features (highest mountains, extensive piedmont platforms, deep gorges, large erosive concavities or huge granitic boulders) in the Villuercas-Ibores-Jara Geopark (Spain); or large Hercynian plutonic intrusions (∼20 km 2 ), spectacular sets of basaltic columnar disjunctions (in a 50 m high escarpment) and deep and narrow erosional canyons, in Orania region (Algeria).…”

Since the 1990s, an international consensus has been emerging with respect to the methods used to identify and assess geosites. These conventional methodologies generally differentiate between the intrinsic or scientific-natural dimension and the social dimension in the potential value of the geological elements. The aim of this article is to analyse the possible existence of other concepts that may underlie these criteria and that could be operating as evaluation parameters even though they are not explicitly and formally described as such in the published studies. An exhaustive analysis of articles on geosite inventories published in Science Citation Index journals in the last 15 years revealed a systematic reference to conceptions of magnitude (in the sense of degree of development and physical prominence) in geosite descriptions around the world, and in particular with respect to sites of geomorphological interest. To contrast this indication, we subjected the geosites inventory of Lanzarote (Canary Islands, Spain) to a Magnitude Rule hypothesis. This inventory is part of the Spanish Geosites Inventory (IELIG, for its initials in Spanish), which was carried out using conventional assessment procedures. Applying this rule, according to which each geosite is the most prominent example of its typology within the reference geological domain, we obtained an almost complete match. That is, geomorphological sites that were selected, a priori, according to intrinsic and social dimension were also (or one could even say ‘actually’) selected, implicitly, on the predominant basis of magnitude. This paper discusses why and how the magnitude parameter may be playing a key role as a subliminal non-explicit driver in the evaluation of geosite relevance, and how this finding may open new perspectives and bring methodological advantages in the inventory of geological heritage.

“…These approaches are mixed because geoheritage is a both objective (real geological objects) and subjective (people's interpretation of these objects). The present study follows the basic principles of the "standard" geoheritage-related studies, the outcomes of which are published in professional international journals (for instance, [37][38][39]).…”

On the Duality of Marine Geoheritage: Evidence from the Abrau Area of the Russian Black Sea Coast

Marine geoheritage is an important but still underdeveloped concept. Field investigations in the Abrau area (Krasnodar Region, southwestern Russia) and subsequent interpretations allow for the characterization of its geoheritage. Two geosites, namely Abrau and Limanchik, are delineated and assessed semi-qualitatively. Their high heritage value, complexity, and appropriate “technical” properties are appraised. The Abrau geosite features Abrau Lake with its enigmatic origin and the outcrops of deformed Upper Cretaceous carbonate flysch deposits. The Limanchik geosite represents an outstanding example of coastal abrasion, Paleocene siliciclastic flysch with trace fossils, and a coastal lagoon separated from the sea by a bar. The heritage aspects of the study areas are related to the development of the Late Cretaceous, Paleocene, and Pliocene seas, as well as to the active dynamics of the Black Sea coastal zone. The duality of marine geoheritage is linked to its relation to both ancient and modern marine environments.
