Analysis of a travertine system controlled by the transpressional activity of the Alhama de Murcia fault: The Carraclaca site, eastern Betic Cordillera, Spain

open access: yesFrontiers in Earth Science, 2023
Continental carbonates, such as travertines and tufas, formed from CO2-rich groundwater degassing as it emerges at the Earth’s surface, are often associated with major crustal-scale faults.

How life affects mineral formation: A reappraisal of concepts and terminology

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
We present a moderately revised terminology of concepts how life may influence mineral formation. This framework would be more consistent and universally applicable. Abstract Numerous biological factors have been proposed to influence the formation of minerals under Earth‐surface conditions, but the underlying concepts are often confused due to ...

Characterization analyzes in the geomechanical behavior of travertine rock

open access: yesSN Applied Sciences, 2023
There is a fundamental interest in studying travertine rocks, and this is to understand their structure, their geomechanical behavior and other particularities in order to guarantee their proper use in different engineering and architectural applications,

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Petrography and U/Th dating of travertine deposits in Bongongo (Cameroon volcanic line): Implication for paleoclimate, hydrothermalism and tectonism

open access: yesSolid Earth Sciences
The studied travertine deposits have been analysed using sedimentology, petrography and geochronology to evaluate their resurgence variation, Neotectonic reconstruction, hydrothermal/paleohydrology, and tectonic influence for their precipitation.

Microfabric controls on the preservation and erosion of Late Pleistocene freshwater microbialites in northwestern Patagonia, Argentina

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
Microfabric distribution controls porosity, preservation and erosion in Late Pleistocene microbialites from the Maquinchao Basin (Argentina). Differential preservation of laminated and shrub fabrics shapes the present morphology of the carbonate build‐ups and influences their palaeoenvironmental interpretation.

Tides of the Midland: From Groundwater Into the River

open access: yesHydrological Processes, Volume 40, Issue 8, August 2026.
Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.

A New Occurrence of Terrestrial Native Iron in the Earth’s Surface: The Ilia Thermogenic Travertine Case, Northwestern Euboea, Greece

open access: yesGeosciences, 2018
Native iron has been identified in an active thermogenic travertine deposit, located at Ilia area (Euboea Island, Greece). The deposit is forming around a hot spring, which is part of a large active metallogenetic hydrothermal system depositing ore ...

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

open access: yesNear Surface Geophysics, Volume 24, Issue 4, Page 364-391, August 2026.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...
