Resource extraction and nature conservation are often seen as opposing concepts.Traditionally,from the viewpoint of nature conservationists,they are only positively associated when rehabilitation efforts are made to restore biodiversity in degraded lands due to extractive activities.Despite these conflicting relationships,in UNESCO Global Geoparks(UGGps),mining and quarrying can act as opening windows in the Earth’s surface exposing geoheritage. 展开更多

This paper is focused on discussing the case of Las Loras UNESCO Global Geopark,in Spain,as an example to show the contribution of Geoparks to the dissemination of science and the relevance of preserving geoheritage by implementing simple measures based on communication and prevention.Natural and anthropic hazards derived from climate change are endangering heritage and the well-ness of the society.Geoheritage is vulnerable.Nowadays we are witnessing the destruction of monuments with high emotional significance due to wars,but climate change is also contributing to the loss of the same cultural heritage.Prevention is often the best way to protect geoheritage from disappearing and society is the best agent to implement preventive measures.Citizens are often unaware of the important treasures they have around them.Geoparks have been a great tool to bring awareness in society,since by involving the public in the whole process of recognition and promotion,they protect the space and the cultural and economic values associated with them.It is important to communicate the initiatives taking place in the Geoparks to explain the importance of geology and the risk of losing the geoheritage if natural hazards increase.Las Loras study is a good practice to implement in other Geoparks. 展开更多

This paper examines World Geopark in South Korea as a case study.It begins by outlining the geological and tectonic background of the Korean Peninsula,whose basement consists of Archean to Paleoproterozoic rocks.These rocks form three continental blocks and constitute a rich geological foundation shaped by multi-stage evolution.The distribution and characteristics of global geoparks are then analyzed.As of 2025,South Korea is home to seven UNESCO Global Geoparks(designated between 2010 and 2025),which feature diverse landforms such as volcanic,sedimentary,and structural formations,with some sites also encompassing cultural relics.Finally,the study highlights that 25 of South Korea's national parks have not yet applied for geopark status and thus hold significant potential.Due to differing evaluation criteria between UNESCO Global Geoparks and South Korea's national parks,future applications involving multiple parks could expand the scale of geoparks,providing valuable insights for geoscience research and park development across East Asia. 展开更多

The fossil shells on the sedimentary rocks were collected from The Historical Park,Ban Sap Noi Geopark,Phetchabun Province,Thailand.However,the fossils remained in this area were investigated on the characteristic species only in geological studies with taxonomy for fossil age predicting.To fill up the gap of these studies,the material characterization techniques were used to study the chemical composition and structure of fossil shells I,II and III.The results clearly showed that the morphologies of all fossil shells were Brachiopod fossils with different species.The functional group and elemental composition of all fossil shells showed that the high content of calcium carbonate was a major composition.In addition,the high content of quartz indicated the silica precipitation phenomenon in all fossil shells.The element composition of cross-sectional morphology and energy dispersive spectroscope (EDS mapping) were used to confirm the presence of Si element in each zone of fossil shells.The crystal structures of all fossil shells were investigated and indicated that the calcium carbonate compound was a calcite phase and silicon dioxide compound was a quartz phase.Moreover,the crystal structure of quartz phase was used to calculate the crystallinity index.The crystallinity index values in all fossil shells indicated a well-crystallized quartz.The age of fossil shells was estimated and found to be brachiopod fossil in carboniferous period with the age of about 359.2 to 299.0 million years. 展开更多

The soil hardness, soil water content and soil bulk density along the trails of six scenic spots in the Zhangjiajie World Geopark were measured and analyzed, and the integrated effects of tourism trampling on soils were evaluated for each scenic spots by calculating its soil impact indexes (SII) in the park. The results indicated that visitors' activities caused a serious influence on the soil in the park, especially in the two most used scenic spots-- Yellowstone Village and Gold Whip Stream. The impact of tourism on soil mainly occurred within 3 m along the trails. The impact shapes are classified into six type as single-sided node type, double-sided node type, cross node type, single-sided linkage type, double-sided linkage type and short-cut linkage type. Of six types of impact shapes, the single-sided node type and double-sided type were dominant. The average water contents of soil for six scenic spots at sample areas of 1 m, 2 m and 3 m from trial is 36.6%, 24.5% and 2.2% lower than that of the control area, respectively. The average soil hardness for six scenic spots at 1m, 2 m, and 3m from the trails tramped increased 167.9%, and 122.2%, and 15.8%, respectively, compared with the control area. Soil bulk density increased 26.5% at 1 m and 20.9% at 2 m from the trails. The main countermeasures for reducing the range and extent of tourism impact on soil are discussed. 展开更多

The author selects a thorny issue of doubled designations that bother policy-makers, professional planners and managers in the field of conservation for protected areas. The analyzed case study areas cover 5 National Geoparks of China in Sichuan Province, 18 UNESCO Global Geoparks in China, and 219 World Heritage sites in China and 8 European nations. Through analysis and synthesis, the author concludes that doubled designation, which also leads to unbalanced park distribution, is particularly prevalent in China other than in Europe. Therefore, on-site management agencies and related governments in China should carefully translate the doubled designations into responsibilities and harmonious partnerships between all stakeholders in order to enhance the management effectiveness and avoid paper park phenomenon. 展开更多

Jeju Island,Korea,was formed through volcanic activity from approximately 1.8 million to 1,000 years ago.The island was designated a Global Geopark in 2010 in recognition of its diverse geoheritage.As part of a special edition for the International Geological Congress 2024,this article shares the latest scholarship on Jeju’s volcanic geoheritage sites to enhance public understanding of the island’s geoheritage as earlier misconceptions continue to spread through books,websites,and information boards,etc.Despite long being interpreted as a typical shield volcano,for example,Mt.Hallasan has been recategorized as a polygenetic and composite volcano that formed through Strombolian eruptions,lava effusions,and magma intrusions from 200,000 to 17,000 years ago.Moreover,although once interpreted as a single scoria cone that formed a thousand years ago,Biyangdo Island(Biyangbong)formed through subaerial volcanic eruptions 26,000 years ago that produced both a scoria cone and a spatter cone.This research is presented with the latest research on other volcano-related Jeju Island Global Geopark geosites,including Suwolbong Tuff Cone and Seongsan Ilchulbong Tuff Ring.Alongside regular research and monitoring,public awareness is essential to ensure sustainable protection due to increasing rockfalls caused by rising sea levels at coastal geosites and climate changeexacerbated freeze-thaw weathering at inland sites on Mt.Hallasan. 展开更多

Since the year 2000 China has created 139 National Geoparks;it started under the guidance of the former UNESCO’s Division of Earth Science,and has therefore become one of the pioneers in this aspect.Many National Geoparks in China have been described over the past decade,but an understanding of the range of various landform features and their connection with geological and climatic constraints has not previously been published.Based on an increasing awareness of National Geoparks,the aim of this contribution is to provide a comprehensive overview of the National Geoparks of China by reviewing the geological heritage and their intrinsic linkages with geological and climatic controls.A regional comparison of the widespread clastic and karst Geopark landforms indicates that the development of these terrains can only be understood within a synthesis of tectonic constraints,climatic changes and lithological properties,whereas the variety of types,forms,scales and development patterns reflect processes in various climatic settings. 展开更多

The Yunmengshan Geopark in northern Beijing is located within the Yanshan range. It contains the Yunmengshan batholith, which is dominated by two plutons: the Yunmengshan gneissic granite and the Shicheng gneissic diorite. Four samples of the Yunmengshan gneissic granite give SHRIMP zircon U-Pb ages from 145 to 141 Ma, whereas four samples of the Shicheng gneissic diorite have ages from 159 Ma to 151 Ma. Dikes that cut the Yunmengshan diorite record SHRIMP zircon U-Pb age of 162±2 and 156±4 Ma. The cumulative plots of zircons from the diorites show a peak age of 155 Ma, without inherited zircon cores, and the peak age of 142 Ma for granite is interpreted as the emplacement age of the Yunmengshan granitic pluton, whose igneous zircons contain inherited zircon cores. The data presented here show that there were two pulses of magmatism: early diorites, followed c13 Ma later by true granites, which incorporated material from an older continental crust. 展开更多
