Table 1 List of samples collected on the field with their occurrence (fracture infillings (F.I.) or host rock (H. R.), locality, with their GPS coordinates when available, clay mineralogy, and petrophysical parameters [ρb: bulk density (g cm⁻³), Φw: water porosity (%), K: permeability (m², measurement limits 10⁻¹⁹–10⁻¹¹ m²)]
