594 Figure 9. Thickening of the edges of a block by over- (C) or underthrusting (B) due to compression from within the weak zones (A). a synform (fig. 9). This scenario offers an alterna tive to the first one although both may concur and joinedly affect the block interior. The re-orientation of the axes of maximum compres sion towards perpendicularity with the trend of the weak lineaments impedes strike-slip faulting within the lineaments if the edge of the blocks are shear free and the principal axes of stress respectively parallel and perpendicular to the edge (fig. 10a). If however the axes are not refracted into a normal po sition, they are inclined to the edges of the block. The lineaments, filled with material of low shear strength, then offer ideal pathways for strike-slip faulting (fig. 10b). This fully confirms the obser vations in 2.2 which testified of oblique-slip strain inside the lineaments. SUMMARY Geological structures with precise tectonic signifi cances and indicative to various degrees of the orien tation of the paleo-stress field in which they were created, can be circumscribed within a framework of transverse lineaments visible on satellite imagery. Structures of this kind are tensional joints, verti cal faults like rift boundary faults, quartz dykes, sedimentary basins of pull-apart origin. Even struc tures of compressive nature seem to relate to the same framework. The latter though might be the sequel of the presence of discontinuities like synsedimentary faults which were later reactivated during compression. During the opening phase the basin marginal faults were seemingly related to the framework. The are res ponsible for two directions of shortening (B normal to B) operative during the same orogeny. The good positive correlation between the theoreti cal stress field within some homogeneous elastic triangle with observed large-scale tectonic features in the northern Andes confirm the validity of the approach. A second order factor in control of the stress field in the framework of intersecting weak discontinuities. The weak zones reflect stress tra jectories in a way which is compatible with the ob served variability of rift directions. This effect de pends on the one hand on the physical conditions in the weak zones and in the blocks and on the boundary loading conditions on the other hand. The refraction of the trajectories inside the lineaments explains how several azimuthal groups of lineaments can give way in coeval strike-slip faulting under the same stress field.
