Testing the Sensitivity of Anisotropy of Magnetic Susceptibility (AMS) to the Regional Tectonic Strain Field in Granite Plutons; Insights From Two Orogen-scale Studies

open access: yesTektonika
Anisotropy of Magnetic Susceptibility (AMS) fabrics within many individual granite plutons have previously been interpreted as recording the regional syn-magmatic tectonic strain field. To test this hypothesis, we compiled a regional database of AMS data

“Hidden” Landscape of Prehistoric Burial Monuments: The Use of Remote Sensing in the Detection of Neolithic Long Barrows in Bohemia (Czech Republic)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

Rifting and arc-related early Paleozoic volcanism along the North Gondwana margin: geochemical and geological evidence from Sardinia (Italy) [PDF]

open access: yes, 2012
Three series of volcanic rocks accumulated during the Cambrian to Silurian in the metasediment-dominated Variscan basement of Sardinia. They provide a record of the changing geodynamic setting of the North Gondwana margin between Upper Cambrian and ...

Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Evidence of hydrological control of Sr behavior in stream water (Strengbach catchment, Vosges mountains, France) [PDF]

open access: yes, 2002
Strontium and particularly 87Sr/86Sr ratios in stream water have often been used to calculate weathering rates in catchments. Nevertheless, in the literature, discharge variation effects on the geochemical behavior of Sr are often omitted or considered ...

The Glacial Legacy of the Geneva Basin: Morphology and implications of an intricate tunnel valley system revealed from 3D seismic data

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Like other perialpine basins and glaciated margins, the Geneva Basin in SW Switzerland is characterised by buried tunnel valleys, which are elongated incisions widely attributed to subglacial meltwater erosion beneath continental ice sheets. However, an inclusive understanding of the geological control on the evolution of the glacial landscape

Thermal evolution of a Variscan syn-orogenic intracontinental basin (Servoz basin, Western Alps): RSCM geothermometry and geochronology

open access: yesSwiss Journal of Geosciences, 2022
The Variscan basement of the Aiguilles-Rouges massif (Western Alps) exposes the Servoz syncline which consists of a metavolcano-sedimentary sequence composed of (i) a volcanic unit of unknown age and origin, (ii) Early Carboniferous sedimentary series ...

Limnological characteristics of 25 lakes of the French Massif Central [PDF]

open access: yesAnnales de Limnologie - International Journal of Limnology, 2002
Les concentrations en elements majeurs des eaux de 25 lacs naturels du Massif Central ont ete determinees a partir de l'analyse chimique de 206 echantillons preleves entre mai 1996 et mai 1998. Pour chaque lac, 6 a 9 echantillons ont ete analyses. Les valeurs moyennes et les ecart-types sont calcules pour les variables chimiques telles que l'alcalinite
