North Caucasus Underground Geophysical Observatory: Instrumentation and Obser…

A full-scale geophysical observatory in the North Caucasus, which was established to study volcanic activity in the Elbrus area, has been functioning for more than 10 years. Results of experimental studies performed at the observatory, located in the deep tunnel, are presented. Special attention is paid to the stability of metrologically significant parameters of precise information-measuring s…

Natural Hydrogen in Uruguay: Catalog of H2-Generating Rocks, Prospective Expl…

The increasing demand for carbon-free energy in recent years has positioned hydrogen as a viable option. However, its current production remains largely dependent on carbon-emitting sources. In this context, natural hydrogen, generated through geological processes in the Earth’s subsurface, has emerged as a promising alternative. The present study provides the first national-scale assessment …

Investigating the Structure of Detachment Faulting and Its Role in Ore Format…

The Kallintiri area (SW Byala Reka–Kechros Dome, Rhodope) hosts a polymetallic (critical, base, and precious metals) ore deposit, tectonically controlled by the late Eocene–Oligocene, top-to-SW Kallintiri Detachment System. The earliest structure associated with the Kallintiri Detachment is a ductile shear zone at the interface between the high-grade footwall gneisses of the Lower and Inter…

Innovative Approaches to Geoscientific Outreach in the Napo Sumaco Aspiring U…

The Napo Sumaco Aspiring UNESCO Global Geopark (NSAUGG) in Ecuador represents a genuine variety of geological, cultural, and natural heritage, which aims to promote sustainable development through geotourism. This study describes the significance of NSAUGG, emphasizing its geological diversity which includes a variety of geosites, and focusing on three recently annexed geosites: the Wawa Sumaco…

How Stiff Was Armorica During the Variscan Orogeny? A Reappraisal of the “B…

In collision belts, the upper plate is generally less deformed than the lower one that underwent syn-metamorphic ductile shearing, and frequently late-collisional crustal melting. Concerning the Variscan orogeny, it is widely accepted that the Armorica microcontinent represented the upper plate of the collision system. In France, the Central-North-Armorican Domain belonged to this upper plate w…

Historical Evolution of the Salento Leccese Coastal Landscape (Southern Apuli…

The Salento Leccese coast (southern Apulia, Italy) is marked both by primary and secondary coasts (cliffs and beaches); beaches, in particular, constitute about a quarter of the coastal perimeter. The Salento Leccese coast experienced dramatic change over the last two centuries due to natural and anthropic causes. This change was reconstructed through a geomorphological survey, historical carto…

Geochronology, Petrogenesis, and Geological Significance of the Longchahe Gra…

Longchahe porphyritic granite is the largest pluton within the western Gejiu complex, a series of mainly intermediate to felsic alkali intrusions in southwestern China. Our research indicates that the pluton intruded during the Late Cretaceous (82–84 Ma). The pluton is primarily a medium- to coarse-grained porphyritic granite, which shows weakly peraluminous (A/CNK = 0.92–1.82, with an aver…

Geochemistry and Petrogenesis of Permo–Triassic Silicic Volcanic Rocks from…

The western side of the Vertiskos Unit crystalline basement in northern Greece is fringed by a Permo–Triassic low-grade metamorphic volcano-sedimentary complex that belongs to the Circum-Rhodope Belt (CRB), which is an important part of the Vardar/ Axios oceanic suture zone. The silicic volcanic rocks from the CRB are mainly rhyolitic to rhyodacitic lavas with aphyric and porphyritic textures…

Geochemical Feed Zone Analysis Based on the Mineral–Solution Equilibrium Hy…

In this work we propose a method of geochemical feed zone (FZ) analysis based on the assumption of thermochemical equilibrium between geothermal fluids and hydrothermal minerals, for each FZ contributing to well discharge. Using our method, it is possible to calculate the mass fraction and the chemistry of each FZ fluid, namely (1) the pH and the concentrations of SiO2, CO2, Na, K, Ca, Mg, HCO3…
