Petrography of the fault-related calcites (slickenfibre calcite). (a) Sketch of the slickenfibre calcite growth over time. Modified from Fagereng et al. [83
]. The orientation of σ
1 is associated with the set of figures (a–d). (b) Petrography of CA18J04-3 sample. This calcite sample comes from a strike-slip fault (site 11, Figure 2
) and could not be dated. Its texture is both fibrous—with a medium and uniform degree of luminescence—and granular—with the presence of growth zonations and a relatively high degree of luminescence. The inclusion bands indicate the syntectonic nature of the sample. (c) Petrography of CA18J06-1 sample (reverse fault-related calcite, Table 2
). Under cathodoluminescence, calcite is uniform with a medium degree of luminescence. The presence of inclusion bands, inclusion trails, and elongated grains indicate the syntectonic nature of the sample. (d) Petrography of CA18J05-1 sample (reverse fault-related calcite, Table 2
). Its texture is granular with the presence of inclusion trails, and the degree of luminescence is relatively low and uniform.
