Suretta nappe shear zones

Dataset
Collected date : from 15 Sep 2011 to 29 Feb 2016

The database "Suretta nappe shear zones" contains petrological, structural and microtextural data of millimetre-scale shear zones from the Roffna rhyolite (Suretta nappe, Eastern Alps, Switzerland). The data consist of structural orientations, optical and electronic images of the mineralogy of the ...

Clay mineralogical and geochemical expressions of the "Late Campanian Event" in the Aquitaine and Paris basins (France): Palaeoenvironmental implications

Dataset
Collected date : from 15 Aug 2013 to 15 May 2014

Campanian sediments from two French sedimentary basins were studied, using clay mineralogy and stable isotope (δ13C and δ18O) geochemistry, in order to investigate the Late Campanian Event. The clay fraction of the Campanian sediments from the Tercis-les-Bains section (Aquitaine Basin) and from the ...

Continental weathering as a driver of Late Cretaceous cooling: new insights from clay mineralogy of Campanian sediments from the southern Tethyan margin to the Boreal realm

Dataset
Disciplines : geology mineralogy
Collected date : from 15 Aug 2014 to 15 Aug 2016

New clay mineralogical analyses have been performed on Campanian sediments from the Tethyan and Boreal realms along a palaeolatitudinal transect from 45° to 20°N (Danish Basin, North Sea, Paris Basin, Mons Basin, Aquitaine Basin, Umbria-Marche Basin and Tunisian Atlas). Significant terrigenous ...

TEOM (Tapered Element Oscillating Microbalance) desert dust measurements in Dédougou (Burkina Faso)

Dataset
Collected date : from Mar 2012 ongoing
Creators : Nadège Martiny

The TEOM (Tapered Element Oscillating Microbalance) instrument was settled in Dedougou (Burkina Faso) in March 2012. It automatically measures the PM10 (particulate matter which diameter is lower than 10µm) mass concentrations at the surface (at 2m) at a 15mn time-step, and day and night. The ...
