Natural site; lacustrine drilling. 153 palynological samples + 19 radiocarbon datings.
Objective : characterize the deformation mechanisms and the crystallographic fabrics within homogeneously deformed granitic samples.
Objective : microtextural characterization within a shear zone brittle precursor
Objective : calculate the crystallographic preferred orientation (CPO) of each mineral phase in order to rebuild the elastic properties of the polyminéralic aggregates.
Objective : compare the chemical compositions of minerals within the brittle precursor and in the host rock.
Objective : characterize the chemical zonings in plagioclase and garnet related to fluid-rock interactions within a shear zone precursor
The significance of late-stage fracturing in the European Alps in a large geodynamic context is reappraised by studying brittle deformations over the entire belt. In the internal Western Alps, paleostress datasets display a major occurrence of orogen-parallel extension resulting in normal faulting ...
GNSS time-series on 6 sites in the French JURA arc, located taking into account a tectonic-neotectonic strategy. The GPS-JURA network is integrated in the French national RENAG network (CNRS-INSU) for research geodesy.
GPS/GNSS observations acquired on OMIV landslides at 24h/30s session/frequency in Rinex standardized file format. Time series of sensor positions and baselines (E, N, Up components).
Seismic waveforms continuous records acquired on OMIV landslides at 250 Hz in miniseed standardized file format. Instrumental catalogue of endogenous seismic events.
Meteorological observations acquired on OMIV landslides using a standardized protocol (6min, 15 min, 30 min, 60 min) according to the measured parameters and transfered in a Ascii standardized file format with the file database management system BD-OH OMIV. Estimation of potential evapotranspiration ...
Data from the JURAQUAKE seismological network. This temporary network is currently composed of 6 seismic stations located north of Besançon and aims to record microseismicity in the area for research purpose.
This database contains a set of petrographical, mineralogical and geochemical data from ores collected in the Bou Arhous deposit in Morocco
Estimates for the riverine export of carbon and of sediments: dissolved organic carbon (DOC) export, particulate organic carbon (POC) export, bicarbonate export, export of bicarbonate being of atmospheric origin (atmospheric CO2 consumption by rock weathering), and sediment export. Estimates are ...
Global map of the main rock types exposed on the continental areas (present day). This map has been constructed and digitized from synthetic lithological and soil maps published by the Food and Agriculture Organization (FAO-UNESCO) for each continent, and from additional other sources. The ...
