“…Oceanic crust emplacement occurred first in the Vavilov basin ($3 -4 Ma) and then shifted toward the east in the Marsili basin ($2 Ma) [Sartori, 1990]. The volcanic activity of the Aeolian Islands started about 1.3 Myr ago and is still active on three of the seven major islands, namely Lipari (last eruption in 729 AD), Stromboli (persistently active), and Vulcano (last eruptions in 1888 -1892) [Beccaluva et al, 1985;Peccerillo, 2003].…”

Tectonics and seismicity of the Tindari Fault System, southern Italy: Crustal deformations at the transition between ongoing contractional and extensional domains located above the edge of a subducting slab

The Tindari Fault System (southern Tyrrhenian Sea, Italy) is a regional zone of brittle deformation located at the transition between ongoing contractional and extensional crustal compartments and lying above the western edge of a narrow subducting slab. Onshore structural data, an offshore seismic reflection profile, and earthquake data are analyzed to constrain the present geometry of the Tindari Fault System and its tectonic evolution since Neogene, including the present seismicity. Results show that this zone of deformation consists of a broad NNW trending system of faults including sets of right‐lateral, left‐lateral, and extensional faults as well as early strike‐slip faults reworked under late extension. Earthquakes and other neotectonic data provide evidence that the Tindari Fault System is still active in the central and northern sectors and mostly accommodates extensional or right‐lateral transtensional displacements on a diffuse array of faults. From these data, a multiphase tectonic history is inferred, including an early phase as a right‐lateral strike‐slip fault and a late extensional reworking under the influence of the subduction‐related processes, which have led to the formation of the Tyrrhenian back‐arc basin. Within the present, regional, geodynamic context, the Tindari Fault System is interpreted as an ongoing accommodation zone between the adjacent contractional and extensional crustal compartments, these tectonic compartments relating to the complex processes of plate convergence occurring in the region. The Tindari Fault System might also be included in an incipient, oblique‐extensional, transfer zone linking the ongoing contractional belts in the Calabrian‐Ionian and southern Tyrrhenian compartments.

“…Extension in the Liguro-Proven•al Basin was then relieved by the opening of the Tyrrhenian Basin. Although rifting in the Tyrrhenian Basin may have started as early as Lower Miocene (post lowerBurdigalian?, Sartori, 1990), the entire basin was not rifted until Tortonian (9 Ma, Sartori, 1990;Kastens, Mascle et al, 1990). Extension was however already active in Alpine Corsica in Late Oligocene or Lower Miocene time, since ductile extension there ended with the deposition of well dated Burdigalian limestones in Corsica and Langhian sediments in the Corsica Basin (Jolivet et al, 1990(Jolivet et al, , 1994.…”

Ce rapport prŽsente un travail commun avec le Laboratoire de gŽodynamique de lÕƒcole normale supŽrieure (ENS). Ce travail doit •tre resituŽ dans son contexte : lÕŽtude rŽgionale du golfe du Lion a ŽtŽ possible dans le cadre du projet europŽen Integrated Basin Studies. Le dŽveloppement du code dÕinversion 3D avait fait lÕobjet de conventions avec lÕENS pendant les annŽes prŽcŽdentes. La mise en Ïuvre dÕune telle inversion est dŽsormais possible ˆ lÕIFP.

LÕaide des coll•gues de lÕENS est souhaitable pour la mise en forme des donnŽes.Il a paru opportun, compte tenu des dŽlais imprŽvus de publication du volume du BSGL* pour lequel cet article a ŽtŽ acceptŽ, de montrer lÕexistence et les potentialitŽs de cette mŽthode.

CONSTRAINTS ON MOHO DEPTH AND CRUSTAL THICKNESS IN THE LIGURO-PROVEN‚AL BASIN FROM A 3D GRAVITY INVERSION: GEODYNAMIC IMPLICATIONS3D gravity modelling is combined with seismic refraction and reflection data to constrain a new Moho depth map in the LiguroProven•al Basin (Western Mediterranean Sea). At seismically controlled points, the misfit between the gravimetric solution and the seismic data is about 2 km for a range of Moho depth between 12 km (deep basin) and 30 km (mainlands). The oceanic crust thickness in the deep basin (5 km En este informe se presenta un trabajo comoen llevado a cabo conjuntamente con el Laboratorio de geodin ‡mica de la Escuela Normal Superior (ENS).

“…We show that (1) extensional processes first started during nappe stacking at the top of the wedge and subsequently continued in backarc environment as in the southwest Tyrrhenian region [Kastens and Mascle, 1990;Sartori, 1990 information is left about the kinematics of the Eocene compressional stage or the geometrical links with the Alps. In an alternative model it is assumed that the polarity of subduction has always been as it is today and that the west vergent thrusts of Alpine Corsica are back thrusts in a large accretionary complex [Principi and Treves, 1984].…”
