A: Tectonic sketch map of the North of Basse-Terre where the main faults observed are reported with measures of the dissolution-schistosity planes and the extension of their trajectories. The red dotted line indicates the boundary between the volcanic complexes of the Basal Complex and the Northern Chain; B: Simplified map of the orientations of lava flows and horizons surface (S₀); C: Rose diagram displaying the faults measured in the Basal Complex; D: Paleotensor obtained by inversion of field data (faults with kinematics criteria, fractures).
