Calcite samples dating. (a) Field picture of the sampling area of ASN201 showing the disposition with the fault plane in Figure 9d. (b) Field picture of ASN201 sample with a texture similar to dilational veins (Roberts and Holdsworth, 2022). (c) A small-scale petrographic picture under polarized light of ASN201 sample. SU5-breccias along the wall of the calcite vein are embedded by the same calcite crystals (same extinction orientations), attesting that calcite precipitated during fracturing. (d) and (e) field pictures of PN201 and PP5, respectively. PN201 calcite vein reopened barite vein. (f) A small-scale petrographic picture under polarized light of a sample from the Payré Estuary outcrop, similar to PN201. The calcite vein is crosscutting barite vein along the interface with an SU2 clasts. Another sub-parallel calcite veinlet crosscuts the barite vein in the upper left corner. (g), (h) and (i) Tera-Wasserburg Concordia diagrams of dated calcite samples, uncertainties are given without and with systematic uncertainties. See Table 1 for brittle structure nomenclature.
