Pan-African Paleostresses and Reactivation of the Eburnean Basement Complex in Southeast Ghana (West Africa)

Table 1

Synthesis of the results of the processing of fracture planes studied at all faulted sites in southeast Ghana. The table summarizes, for each site, the geographic coordinates, the rock type (Rt) involved (DC = dolomitic carbonate, S-Q = sandstone or quartzite, MQ = micaceous quartzite, QS = quartzite and schist, G = granulite, OG = orthogneiss, MG = migmatitic gneiss, M-G = migmatite and granite), the number of planes (Np), plane type (Pt) analyzed (SSF = strike-slip faults, RF = reverse faults, and NF = normal faults), and trend and plunge of main paleostress axes ( 𝜎 1, 𝜎 2, 𝜎 3) obtained.
