Detailed Ar/Ar results. Signal values are given in volts along with ages calculated for each step (which error excludes that on J factor on individual steps). 40Ar(r) and 39Ar(k) respectively shows the percentage of radiogenic argon (corrected from atmospheric input) over the total 40Ar released, and the percentage of 39Ar resulting from 39K transmutation only over the total 39Ar released. Dashed inputs correspond to negative signal value after blanc corrections, which was often the case for 37Ar whose amount was almost null in muscovites.

Far left: field picture with sample location (Red frame). Left: thin section picture under polarized – analysed light. The red frame corresponds to the zone mapped by the Fabric analyzer. Center: quartz <C> axis orientation map (6.8 mm spatial step) with associated orientation colour wheel. Right: one point per pixel stereographic projection (lower hemisphere – equal angle) with density contours and colour scale for density. Far right: interpretation.
