General metadata
Data acquisition date :
from 1 Oct 2020 ongoing
Data acquisition methods :
- Observational data : The mineralogical observations were interpreted by the digital and optical microscope of the Chrono-environment laboratory.
SEM images were acquired with an APREO S (C13) at the FEMTO institute of Besançon operating at 30 kv with a current of 3.2 nA. - Experimental data : High resolution X-ray mappings were acquired with a JEOL-8200 microprobe at the Institute of Geological Sciences of the University of Bern at the following operating conditions: 15kV, 100 nA with a pixel resolution of 6 μm and a dwell time of 90 ms/pixel.
- Simulation or computational data : Perple_X and PyWerami were the two softwares that were used for the thermodynamic modelling as well as for the study of density variation.
These two softwares use the Holland and Powell database of 1992.

Additional information :
Data collected as part of a Master GAP (Besançon) Geology internship, co-supervised by Philippe Goncalves (associate professor at the Chrono-environment laboratory) and Kevin Mahan (associate professor at the University of Boulder).
Mineralogical data were observed and processed at the Chrono-environnement laboratory and the FEMTO-ST institute. Chemical X-ray mapping analyses were produced at the University of Bern (Switzerland).
