(A) Geological sketch of the Paikon zone in the Voras Tzena Mts (north of the Aridhea Almopias Plain). Same symbols as on Fig. 4B. The Paikon Massif is separated from the Tzena-Malarupa Massif by the dextral strike-slip Voras fault zone superimposed upon a Jurassic probably oceanic transform fault (see text). (B) Structural sketch of the southern Paikon Massif (drawn from Jannitsa geol. sheet, Mercier et al., 2005). Same symbols as on Figure 4B; −ster. A1: NNW-SSE striking (B₁) fold axes with a western vergence affecting the Pirghos fm. at the Megha Rema (A1-A2), site (D₁ event); −ster. A2: NE-SW (B₂) fold axes with an eastern vergence refolding the B₁ folds. It is important to underline that the small B₁ folds are numerous in the reverse limbs of the B₂ large folds (cartoons on Fig. 9). Thus, being inverted, their apparent dissymmetry may wrongly suggest that the B₁ folds (D₁ event) have an eastern vergence; −ster. A3: vergence of the folds of D₃ and D₄ events, striking ∼NW-SE and ∼W-E, respectively, indicated on figure by arrows with green and green-yellow arrow heads, respectively; ster. A4: axes of the folds of the D₃ and D₄ events. Section I in southern Paikon (see Fig. 9); Section II, double line in N. Paikon shows the thrust of the Kastaneri unit upon the Late Cretaceous Gola Tchouka unit, the Gandatch Late Cretaceous syncline is probably a Gola Tchouka klippe re-folded.
