Clay minerals are helpful markers of low-temperature geological processes. The combination of their characterization with geochronology is a powerful tool to constrain physical and chemical processes, improving our understanding of the evolution of the Earth system. This paper aims to present the platform along with the associated methods developed at the GeoRessources laboratory (University of Lorraine) to separate, characterize clay minerals and date illites using the K-Ar method.

In this paper, a 26-year-long time series of total ozone column above Arctic Research Center in Sodankylä is presented. The time series is produced using a uniform method, presented in the paper, for retrieving the ozone column from the measurements. The data are checked for obvious errors and filtered automatically and manually to ensure that only good-quality data are delivered to public databases. Some features of the time series are highlighted and availability of the measurements is presented.

We present a new real-time experimental setup for analysing in continuum radon emissions over variable stress-strain regimes. The setup consists of a radon accumulation chamber that can host large cylindrical rock samples and is connected to a RAD7 radon monitor. The radon signal is enhanced using a heating system. The accumulation chamber is then placed into a uniaxial testing apparatus that allows obtaining a variety of deformation conditions.
