A palaeoearthquake event and its age revealed by the travertine layer along the Litang fault in the southeastern margin of the Qinghai-Tibetan plateau

Earthquake Research Advances, 2023
The Litang fault (LTF), located in the southeast of the Qinghai-Tibetan Plateau, is known for its high level of present-day seismicity, whereas its Pleistocene activity has been scarcely documented.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Physical and mechanical appraisal of two carbonatic stones widely used in the architectural heritage of eastern Andalusia, Spain

Materiales de Construccion, 2011
We present a detailed characterization of two calcareous stones from Andalusia (Southern Spain), namely Escúzar calcarenite and Olivillo travertine. Both materials can replace two stones extensively used in the architectural heritage of Andalusia, i.e ...

Assessment of radiological hazards of travertine rocks as building materials [PDF]

Iranian Journal of Medical Physics, 2019
Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human

Description of Flavicapitulum gen. nov. and two new species of Marmoreocelis from thermal habitats in the Americas

Journal of Phycology, EarlyView.
Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.

Tides of the Midland: From Groundwater Into the River

Hydrological 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.

Environmental changes and human settlement in the central Marches (Italy) during the early-middle Holocene

Physio-Géo, 2007
In the Early Holocene, the central Marches (Italy) underwent a widespread development of forest cover and soils which drastically reduced slope degradation and related aggradation processes in riverbeds.

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

Near 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 ...
