abstract = {The Cadomian Orogeny produced a subduction-related orogen along the periphery of Gondwana
and configured the pre-Variscan basement of the Iberian Massif. The architecture of the Cadomian Orogen
requires detailed structural analysis for reconstruction because of severe tectonic reworking during the
Paleozoic (Variscan cycle). Tectonometamorphic analysis and data compilation in SW Iberia (La Serena
Massif, Spain) have allowed the identification of three Cadomian deformation phases and further constrained
the global architecture and large-scale processes that contributed to the Ediacaran building and early Paleozoic
dismantling of the Cadomian Orogen. The first phase (DC1, prior to 573 Ma) favored tabular morphology in
plutons that intruded during the building of a continental arc. The second phase (DC2, 573–535 Ma) produced
an upright folding and contributed to further crustal thickening. The third phase of deformation (DC3,
ranging between ∼535 and ∼480 Ma) resulted in an orogen-parallel dome with oblique extensional flow. DC1
represents the crustal growth and thickening stage. DC2 is synchronous with a period of crustal thickening
that affected most of the Gondwanan periphery, from the most external sections (Cadomian fore-arc) to the
inner ones (Cadomian back-arc). We explain DC2 as a consequence of flat subduction, which was followed by
a period dominated by crustal extension (DC3) upon roll-back of the lower plate. The Ediacaran construction
of the Cadomian Orogen (DC1 and DC2) requires ongoing subduction beneath Gondwana s.l., whereas its
dismantlement during the Early Paleozoic is compatible with oblique, sinistral convergence.},
