“…Geoheritage related to Devonian reefs is not abundant on the global scale [Ruban, 2023]. Two representative examples include the Schlade Valley in the Rhenisch Massif of Germany [74] and the Jebilet region in the Jebel Ardouz massif of Morocco [64].…”

“…They are covered only marginally in the famous PARED database [29], although their consideration can be important to better understand the shift from reef abundance in the Early-Middle Devonian to their decline at the Devonian-Carboniferous transition [30]. Moreover, the geoheritage-related knowledge of pre-Quaternary reefs, including those of Late Devonian age, remains poor [31], and, thus, investigations of the Devonian reefs of the Altai will help to fill this gap. The objective of the present paper is to analyze the Neverovsky palaeoreef and some associated features at the western edge of the Altai in terms of their geoheritage.…”

The Rudny Altai is a western segment of the Altai orogenic belt. Its geological richness makes its geoheritage exploration an urgent matter. Investigations in the Loktevsky District (Altai Region, Russian Federation) have led to the finding of three notable localities, which are proposed as geosites. Field investigations and both qualitative and semi-quantitative (scoring by criteria) studies were carried out to characterize and value the geoheritage properties of these localities. The Neverovsky palaeoreef is a relatively large geosite, representing a Frasnian reef developed on a volcanic edifice. The Zolotukha section and the Razdolnoe section are smaller geosites representing deep-marine facies of the Giventian–Frasnian transition and the late Frasnian, respectively. Seven geoheritage types are established in the Neverovsky palaeoreef, and four geoheritage types are established in the other two geosites. Examination of rarity, accessibility, vulnerability, and other properties allows the ranking of the Neverovsky palaeoreef globally and the other two geosites regionally. The three proposed geosites need special geoconservation measures (especially regarding their rich fossil content). The palaeoreef can be used for the promotion of local tourism.

“…Thus, the IB witnesses the climatic optimum at the Mesozoic/Cenozoic transition. A similar direct link to ancient environments different than the present-day one can be explored at geosites exposing reef limestones, whose very existence points to warm climate at the time of coral reef growth [66]. The Lesvos Island UGGp in Greece includes several localities where petrified (silicified) wood is exposed, uncovered from beneath pyroclastic deposits of Miocene age [40].…”

Geosites and Climate Change—A Review and Conceptual Framework

Geosites are windows into the geological past, which may be recorded in rocks and their properties, the fossil content, and landform produced by processes no longer operating. Since the histories of sedimentation, life, and landscape evolution are to a certain extent controlled by climatic conditions, some geosites may be used as illustrations of various themes linked to the issue of climate change. In this paper, a coherent systematic framework is proposed for how to look at geosites through the lens of climate change. Four major aspects of relevance are recognized: (i) geosites providing evidence of changing climatic conditions in the past; (ii) geosites providing evidence of an environment different than that of today at the place; (iii) geosites providing evidence of extreme weather events; and (iv) dynamic geosites, subject to change as a response to ongoing climate change. The use of geosites to raise awareness and educate the public about climate change faces various interpretation challenges. In particular, linking with ongoing climate change requires caution and balanced presentation as most geosites record changes which occurred without any anthropogenic component. The preferred focus should be on environmental instability in general rather than on any specific reasons for change.

“…As such, the aim of this work is to characterize the submerged geoheritage of four offshore volcanic swells located in the Gulf of Guinea in light of the origin and evolution of the coral reefs' morphology as proposed by Darwin and sea-level changes during the last 30 My. Based on the "art of storytelling" [24], each of them is described as representing successive subsidence stages on foundering volcanic island bases according to Darwin's hypothesis and considering its potential use for geoeducation and geotouristic purposes [25]. The purpose of this work is to support and contribute to ongoing initiatives within the Community of Portuguese-speaking Countries that aim to promote the African geological heritage [26] and to help put local projects into action that will help promote local socio-economic sustainable development [27].…”

A Geo-Itinerary to Foster Sustainable Tourism in West African Islands: Storytelling the Evolution of the Ancient Cameroon Volcanic Line Coral Reefs

This study characterizes the submerged geomorphology around Annobón, São Tomé, and Príncipe Islands, and the De Santarém–Escobar seamount in the Cameroon Volcanic Line or CVL (Gulf of Guinea, West Africa) through analyses of topographic relief and coastal bathymetry, and data from fieldwork and historical fossil collections. The clear relation between each submerged island and the seamount morphology of the CVL and the various stages of coral reef development according to Darwin’s subsidence hypothesis meets the concept of intangible geoheritage. This type of geoheritage is related to phenomena rather than to a thing, and it is usually highly evaluated by scientific communities. Academics tend to use science-based discourse to explain this theory, but it is rarely understood by non-specialist audiences. This work proposes a virtual geo-itinerary along the submerged geomorphology of the CVL islands and seamounts, which aims at telling the geohistory of the coral reefs’ origin and evolution according to Darwin’s theory, and disclosing its geoheritage contents for further sustainable uses. The resulting narrative can be used to support geotourism initiatives and to support the United Nations’ objectives for Small Island Developing States.
