\begin{abstract}
The Newfoundland-Iberia rift, which includes the Lusitanian Basin (LB),
has been considered the archetype of a magma-poor rift, but its main
steps are still debated. The new data reported here indicate that the
LB's eastern border comprises two contrasting types of contact between
continental sediments and Variscan basement: major angular unconformity
and master bounding fault. The unconformable contact could mean a
pre-rift sag basin, or a syn-rift half-graben with flexural boundary in
the E. However, given that newly recognized master NW-SE to NNW-SSE
bounding faults displace the red continental deposits and basal
unconformity by hundreds of meters, we infer that the master bounding
fault is Alpine and displaces the base of a previous sag basin. In the
case of unconformable contact and sag basin, the age of the red
continental deposits would be older than the currently attributed Late
Triassic age, and represent the missing Late Variscan denudation
molasse. It seems therefore that the LB could be a rift basin underlain
by an older and smaller sag basin. Later, Pangaea rifting produced a
full graben, the LB, bounded to the east by a newly mapped master fault
reactivating a major Variscan shear zone in the northern half of the
Lusitanian Basin. A similar development of composite basins can be found
in NE Brazil, where some Mesozoic intracontinental basins also show
evidence of two-stage basin formation, an early sag (Palaeozoic) and a
later rift (Mesozoic).%
