摘要: Abstract Mesostructural analysis carried out in several localities of western, southern-central and southeastern Iceland shows an unexpectedly frequent occurrence strike-slip faults parallel to, or lying at relatively small angles with, the axis rifting. Some can be interpreted terms shear to rifts, whereas others form conjugate systems referable rift-parallel compression. Axial explained by accommodation differences directions tectonic extension between different segments axial rift system subordinately lateral (rift-parallel) displacements major lithospheric plates. compression may attributable rift-oblique transform mantle transport spreading compensating local deficiencies upwelling. The data regard 1974 fault surfaces, mainly small-scale.
