Aquifers’ storability potential in Alice, comprising rocks of the Beaufort Group in the Karoo Supergroup, is examined based on the mineralogical and diagenetic implications of sandstones and mudstones. This investigation is focused on SEM + EDX...
The Southern Ocean waters exchange freshwater, nutrients, carbon, heat, and salt to the Equator and influence the global carbon budget. Therefore, it is essential to understand the variations in Southern Ocean circulation during the last deglacial pe...
The phrase “Mesozoic marine revolution” refers to the Mesozoic origin of durophagous predators and the co-evolutionary response of their prey as well as an increase in infaunalization. However, using “revolution” for a process...
Snow is one of the most important sources of water in most parts of the world, supplying approximately a third of the water needed for agricultural activities, drinking, and underground water sources. The runoff caused by melted snow can be destructi...
The nature of carbonate rock’s heterogeneity under subsurface conditions is still under debate due to significant variations in mineral composition and changes in rock texture during/after diagenesis. However, several studies have utilized faci...
Geophysical natural hazards, such as earthquakes and volcano eruptions, can have catastrophic effects on the population depending on the location and quality of construction. From the geophysical point of view, several aspects are still debated in th...
The last volcanic eruption in Western Samoa, which occurred between 1905 and 1911, produced a complex scoria and lava spatter cone and an extensive lava field that destroyed Sale’aula village, near the Pacific coast. This eruption, referred to...
The Arxan–Chaihe volcanic field (ACVF) is a Pliocene to recent intracontinental monogenetic volcanic field. Within the ACVF, at least 47 vents are preserved in a ~2000 km2 area, forming two major NE-SW trending structural elements. The youngest...
In the Brazilian state of São Paulo, the coastal municipalities have watersheds in mountains with active relief evolution (Serra do Mar). The coastal regions are more vulnerable to flooding and landslides. A large number of people live on the...
Currently, the Moulay Bousselham lagoon faces a pressing issue of sediment buildup, particularly in the inlet zone, which has led to the formation of sandy areas known as “sandpits” and poses the threat of inlet closure. This environmenta...
Since its last eruption in 1990–1995, the Unzen volcano (Shimabara Peninsula, Japan) has been quiescent. At its summit, a complex dacitic dome spreads toward the East, in the direction of the Mizunashigawa valley. In a precarious equilibrium, s...
Geology, as a basic science within the natural sciences, is one of the key areas of knowledge for students in both primary and secondary education. However, when teaching the areas related to geology, many doubts arise both for teachers and students....
Droughts during the growing season are projected to increase in frequency and severity in Iran. Thus, area-wide monitoring of agricultural drought in this region is becoming more and more important. Changes in precipitation patterns are caused by ext...
When a disaster occurs, society at risk is not only threatened by the consequences of this event. Stable and trigger factors generate a natural hazard, which in turn induces changes in some trigger factors, and thereby, these changes can induce anoth...
In the Canary Islands, sixteen historical eruptions have been documented in Lanzarote, Tenerife, El Hierro, and La Palma. The latest eruption, the Tajogaite eruption, occurred in 2021 in La Palma and the richness and diversity of the natural and cult...
Geosites, meaning the places of geological interest, have gained notoriety nowadays, positioning themselves as one of the most important resources in educational strategies for earth and environmental sciences. The possibility of observing the result...
This study proposes a methodology to calculate the C-factor using remote sensing data: NDVI from LANDSAT image and MAPBIOMAS Land Use (LU) classification of Atibaia river watershed, Brazil, to improve the estimation of risk of soil loss using equatio...
Glacier velocity is one of the critical parameters for understanding the current health status of a glacier. According to the momentum law, mass is inversely proportional to velocity. A higher velocity may indicate a lower mass. Fifteen transboundary...
Typhoon hazard assessment is the basis of loss estimation and disaster prevention and mitigation. This study investigates the use of the grid fixed-point method to assess typhoon hazards. We conducted experiments on the southeast coast of China based...
A total of 91 geological sites of scientific, touristic, and educational interest were inventoried, following a survey under the project “Development of geotourism products in the tourist destination Patagonia Verde”. This project was dev...
The phylogenetic relationships of turtles (Testudines) challenge cladistics by demonstrating the inherent weaknesses of this non-Darwinian method of phylogenic reconstruction. Recent cladistic analyses have identified sauropterygians as the closest r...
The coastal area of Safi between Cap Beddouza and Jorf Lihoudi is dominated by different forms of marine cliffs forming the coastline, with rock formations ranging from Jurassic to Quaternary. The main coastal geological risk is the instabilities of...
The paleontological analysis of the fauna of ammonites collected in the marl–limestone series of the Pliensbachian and The Toarcian of the Es-Saffeh Mountains (Tiaret, western Algeria) brings new data to the Oceanic Anoxic Event of the lower To...
The relict (palimpsest and lowstand) deposits of the Cilento continental shelf were analyzed based on the geological interpretation of Sub-Bottom Chirp sections, calibrated with core data. A progradational unit, which is overlying the acoustic baseme...
In recent decades, heavy metal contamination in soils has caused global concern. Quantitative apportionment of heavy metal sources in the surface soil is a complex task. This study indicated a receptor model to evaluate the heavy metal concentrations...
The travertines of El Ksiba form cliffs with an extension of about 8 km and a variable height that can reach about thirty meters. They are developed on lacustrine limestones and conglomerates of early Quaternary age. The results reveal the high scien...
The Spanish education system is undergoing a profound transformation due to the implementation of a new education law. In this work, we will make a comparison between the old and new educational laws about content related to Geology in primary educat...
The Known Fossil Record represents museum collections and the published literature, and it is subject to multiple large-scale megabiases grouped into four major categories: (1) taphonomy; (2) rock preservation; (3) fossil discovery; and (4) fossil st...
Flood is one of the most damaging natural hazards, and timely detection of it is very important to save human lives and assess the level of damage. The occurrence of floods in cloudy weather conditions makes the use of radar-based sensors for real-ti...
The Ouzoud syncline, in central Morocco, is one of the kingdom’s wealthiest areas of natural and cultural heritage. This syncline has significant potential for geotourism development; it contains the Ouzoud waterfalls, one of the most coveted t...
In the last decade, rainfall radars have been deployed at volcanoes such as Mt. Merapi in Indonesia and can even cover a whole country such as in Japan, where the X-Rain (eXtended Radar Information network) product has been available for local resear...
Changes in Southern Ocean physics are dynamically linked to westerly winds, ocean currents, and the distribution of Antarctic sea ice in the Southern Hemisphere. As a result, it is critical to comprehend the response of Southern Ocean physics to the...
The studied section, up to 10 m thick with 17 different carbonate beds, showed the interaction between a giant slide and the pre-existing normal faults during the upper Cretaceous time. There are three major points of consideration in the studied sec...
