  abstract = {{D}uring the {A}lgerian-{F}rench {SPIRAL} survey aimed at investigating the deep structure of the {A}lgerian margin and basin, two coincident wide-angle and reflection seismic profiles were acquired in central {A}lgeria, offshore {G}reater {K}abylia, together with gravimetric, bathymetric and magnetic data. {T}his 260 km-long offshore-onshore profile spans the {B}alearic basin, the central {A}lgerian margin and the {G}reater {K}abylia block up to the southward limit of the internal zones onshore. {R}esults are obtained from modeling and interpretation of the combined data sets. {T}he {A}lgerian basin offshore {G}reater {K}abylia is floored by a thin oceanic crust (similar to 4 km) with {P}-wave velocities ranging between 5.2 and 6.8 km/s. {I}n the northern {H}annibal {H}igh region, the atypical 3-layer crustal structure is interpreted as volcanic products stacked over a thin crust similar to that bordering the margin and related to {M}iocene post-accretion volcanism. {T}hese results support a two-step back-arc opening of the west-{A}lgerian basin, comprising oceanic crust accretion during the first southward stage, and a magmatic and probably tectonic reworking of this young oceanic basement during the second, westward, opening phase. {T}he structure of the central {A}lgerian margin is that of a narrow (similar to 70 km), magma-poor rifted margin, with a wider zone of distal thinned continental crust than on the other margin segments. {T}here is no evidence for mantle exhumation in the sharp ocean-continent transition, but transcurrent movements during the second opening phase may have changed its initial geometry. {T}he {P}lio-{Q}uaternary inversion of the margin related to ongoing convergence between {A}frica and {E}urasia is expressed by a blind thrust system under the margin rising toward the surface at the slope toe, and by an isostatic disequilibrium resulting from opposite flexures of two plates decoupled at the continental slope. {T}his disequilibrium is likely responsible for the peculiar asymmetrical shape of the crustal neck that may thus be a characteristic feature of inverted rifted margins.},
