A model for the concomitant early formation of dolomite and fibrous clays in coastal bay systems: Evidence from the Eocene (Paris Basin, France)

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.
ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...

Weak and Shallow Secondary Frictional Faults Revealed by Large Earthquakes in Haiti

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Geological, geodetic, and seismological observations show that large earthquakes damage the crust surrounding the main rupture and, sometimes, activate nearby, smaller, secondary faults. However, the long‐term tectonic role of such secondary faults and their behavior in response to earthquakes or tectonic loading are unclear.

Osmotische Wirkung von Kochsalz: Ein Schülerexperiment zur Bestimmung der Zellsaftkonzentration bei verschiedenen Gemüsearten

PraxisForschungLehrer*innenBildung, 2020
Salze sind für Lebewesen lebenswichtig. In hohen Konzentrationen wirken sie aber u.U. toxisch. In vorhergehenden Unterrichtseinheiten haben sich die Schüler*innen bereits mit dem Aufbau und der Struktur von tierischen und pflanzlichen Zellen beschäftigt.

Feasibility study of the AOSTA experimental campaign

EPJ Web of Conferences, 2016
The reduction of the nuclear waste is one of the most important nuclear issues. The high radiotoxicity of the spent fuel is due to plutonium and some minor actinides (MAs) such as neptunium, americium and curium, above all. One way to reduce their hazard
