Geological map and cross-section of the area around the hamlet of Barlet showing the lithologies in the Barlet unit and Langeac basin. The Barlet unit is a tectonic melange of gneiss lenses in a schist matrix and is richly mineralized with Sb and F deposits. Positions and maximum depths of the Marsanges coal mine (1) and La Dreyt fluorite mine (2) are shown in the cross-section. Sample localities are shown on the geological map.
Mineral analyses have been performed by WDS electron-microprobe analyses 232 and results are provided as a
supplementary datafile.
