Beach Rock

Beach rock (đá bãi biển-BR) hình thành khi lớp trầm tích bãi biển trở nên rắn chắc nhờ tích tụ thứ sinh của cacbonat canxi (canxit, aragonit) kết tủa từ nước ngầm trong đới dao động của thủy triều[1]. Loại đá này từ dễ vỡ tới gắn kết tốt, bao gồm hỗn hợp các loại trầm tích cỡ hạt bột, cát và cuội sạn, có nguồn gốc từ các mảnh thân mềm, san hô, mảnh đá các loại, cả các vật liệu khác như mảnh gỗ, dừa, thậm chí cả vật dụng như chai lọ, mảnh gốm... BR thường là cát sạn kết, nhưng cũng có khi là dăm kết và cuội kết, có cấu tạo phân lớp nằm nghiêng, thường được hình thành dưới một lớp phủ mỏng trầm tích bở rời. Chúng lộ ra do xói lở bờ biển và cát phủ trên bị cuốn đi. BR thường hình thành trong đới gian triều vùng nhiệt đới hoặc cận nhiệt đới, được tìm thấy ở vùng biển Caribe, Địa Trung Hải, Biển Đỏ và vịnh Ả Rập, bờ biển Brazil, Nam Phi, Úc và ở Đông Nam Á.

Morphological System

A planície costeira brasileira, em especial a do Nordeste do Brasil, apresenta um sistema morfológico que sofre diversas pressões do ponto de vista do uso e ocupação dos seus espaços. Logo, o entendimento da dinâmica natural e espacial desse ambiente requer a adoção de metodologias que contemplem uma abordagem em múltiplas escalas. Neste sentido, este trabalho tem o intuito de analisar as múltiplas morfologias associadas a praia das Fontes, em Beberibe-CE, em diferentes escalas taxonômicas. Esta análise auxiliou na realização de um prognostico das condições ambientais e de sua capacidade de suporte. Metodologicamente aplicou-se a proposta de Bertrand (1971), adotando-se apenas as unidades inferiores que inclui os níveis taxonômicos regionais e/ou locais, compreendendo os geossistemas, geofáciese os geótopos. Os resultados alcançados foram satisfatórios, uma vez que as unidades mapeadas foram validadas em atividades de campo para reconhecimento do produto cartográfico.Palavras-chave: Análise Multiescalar.

Therefore, the understanding of the natural and spatial dynamics of this environment requires the adoption of methodologies that contemplate a multi-scale approach. In this sense, this work has the purpose of analyzing the multiple morphologies associated to Praia das Fontes, in Beberibe-CE, at different taxonomic scales. This analysis assisted in the accomplishment of a prognosis of the environmental conditions and their support capacity. Methodologically Bertrand's (1972) proposal was applied, adopting only the lower units that includes regional and / or local taxonomic levels, including geosystems, geophysics and geo-objects. The results were satisfactory, since the mapped units were validated in field activities to recognize the cartographic product.Keywords: Multiscalar Analysis. Coastal Geomorphology.

From the middle of the 1990s, geotourism was introduced through the first geotrails, their evolution, and the first geopark worldwide in Gerolstein/Vulkaneifel, Germany. The latter is one of the founding members of the European Geoparks Network, which was established in 2000 at the International Tourism Bourse (ITB) in Berlin. The main goal of the first geopark was to link geological heritage with tourism in a rural area that was trying to create new perspectives to inspire young people to stay in their home territory. Geotourism was initiated as part of sustainable tourist development and for future sustainable development at that time in the Gerolstein region. The first steps to implement the Gerolstein/Vulkaneifel Geopark, Germany, were taken in 1992. The core aspects included geological heritage, science transfer, and education as tools for developing geotourism in the broad sense and integrating local people and municipalities in the geopark activities of the rural region. Close collaboration with the local and regional tourism organizations highlighted the need to both define tools and demonstrate their success. Up to now, practice has shown that such success can be demonstrated by the infrastructure created, as well as adjacent measures and activities. A network of factors was determined to play a significant role in ensuring the successful sustainable development in a geopark across the field of geotourism. There are many activities and publications on geological heritage, geosite assessment, significance, and use, but there are fewer which reflect on the network of factors highlighted in this contribution which were first presented in 2002. In many publications and investigations, one factor in particular is emphasized, e.g., infrastructure development, such as panels or other items. Not all of the mentioned factors, however, are being addressed. As a result, a selection of good practice examples of UNESCO Global Geoparks (UGGP) working on the network-oriented conceptual basis has been studied here, in line with the conceptual principle set forth about 25 years ago. The geopark examples in this study include Lesvos Island UGGp (Greece), Naturtejo UGGP (Portugal), Vulkaneifel UGGp (Germany), and Hong Kong UGGP (China), as well as the example of the Messel Pit World Heritage Site (WHS) (Germany). The latter was integrated to present an example which is not a geopark, showing that this concept can also be transferred to a WHS as a tool for sustainable development according the UN 2030 Agenda. The information on the development of the selected examples was obtained by visiting the geopark territory and from the geopark’s websites and published material as a combined methodology.

The Cenozoic Malaguide Basin from Sierra Espuña (Internal Betic Zone, S Spain) due to the quality of outcropping, areal representation, and continuity in the sedimentation can be considered a key-basin. In the last 30 years, a large number of studies with very different methodological approaches have been done in the area. Models indicate an evolution from passive margin to wedge-top basin from Late Cretaceous to Early Miocene. Sedimentation changes from limestone platforms with scarce terrigenous inputs, during the Paleocene to Early Oligocene, to the deep basin with huge supplies of turbidite sandstones and conglomerates during the Late Oligocene to Early Miocene. The area now appears structured as an antiformal stack with evidence of synsedimentary tectonics. The Cenozoic tectono-sedimentary basin evolution is related to three phases: (1) flexural tectonics during most of the Paleogene times to create the basin; (2) fault and fold compartmentation of the basin with the creation of structural highs and subsiding areas related to blind-fault-propagation folds, deforming the basin from south to north during Late Oligocene to Early Aquitanian times; (3) thin-skin thrusting tectonics when the basin began to be eroded during the Late Aquitanian-Burdigalian. In recent times some works on the geological heritage of the area have been performed trying to diffuse different geological aspects of the sector to the general public. A review of the studies performed and the revisiting of the area allow proposing different key-outcrops to follow the tectono-sedimentary evolution of the Cenozoic basin from this area. Eight sites of geological interest have been selected (Cretaceous-Cenozoic boundary, Paleocene Mula Fm, Lower Eocene Espuña-Valdelaparra Fms, Middle Eocene Malvariche-Cánovas Fms, Lowermost Oligocene As Fm, Upper Oligocene-Lower Aquitanian Bosque Fm, Upper Oligocene-Aquitanian Río Pliego Fm, Burdigalian El Niño Fm) and an evaluation has been performed to obtain four parameters: the scientific value, the educational and touristic potential, and the degradation risk. The firsts three parameters obtained values above 50 being considered of “high” or “very high” interest (“very high” in most of the cases). The last parameter shows always values below 50 indicating a “moderate” or “low” risk of degradation. The obtained values allow us considering the tectono-sedimentary evolution of this basin worthy of being proposed as a geological heritage.

AbstractThe Western Sichuan Plateau (WSP), located in the eastern margin of the Qinghai–Tibet Plateau, is the most strongly deformed region of the continental crust in China. Frequent tectonic movements shape the unique topography and landform of the WSP and have also produced abundant geological heritage resources. Based on the existing geological heritage survey data in Sichuan Province, the nearest index analysis method of employing a regional spatial point model was used to reveal the distribution rules and the genetic mechanism of typical geological relics in the WSP for the first time. Results indicate that the formation and distribution of geological relics in the WSP are generally controlled by tectonic movement and supplemented by the comprehensive action of external forces such as flowing water. Their distribution shows a condensed spatial distribution pattern and extends along the strike of a fault zone and river strike strip. Finally, based on the characteristics of geological relics in the WSP, some suggestions on the protection and development of regional geological relics were put forward.

The Zaruma-Portovelo mining district in Ecuador, and in particular, Portovelo City, is home to the oldest mining museum in the country. This museum, named Museo Mineralógico Magner Turner (MMMT in Spanish), is a centre that reflects, through its collections, the history and culture of this territory. This work aimed to evaluate the MMMT as a possible geosite by analysing its contributions to the geomining heritage of the Zaruma-Portovelo district, and thus, to enhance it and promote its collections as a geotouristic attraction. The work involved three phases: (i) describing the museum and its surroundings; (ii) a semiquantitative evaluation of the museum using the Brilha method and a geosites assessment model (GAM); and (iii) a qualitative evaluation using the Delphi and SWOT methodologies to define strategies and proposals for museum development. The results obtained by the semiquantitative evaluation of the geosite with the Brilha method reflect high scientific (330/400), educational (380/400) and touristic (365/400) appeal. The applied GAM shows the museum as a geosite with high principal and additional value, placing it in the Z33 field of the global valuation matrix. In addition, the semiquantitative and qualitative evaluation made it possible to describe the importance of the museum and its collections in the development of the area. The study carried out qualified the museum as a mining site with an appropriate valuation, an example of ex-situ geological heritage conservation and a basis for geotourism development.
