A critical revision of the Liguride complex in the Pollino area (Southern Apennines)

2020
<p>The geodynamic reconstructions of the Apennine-Tyrrhenian system strongly rely on chronological and P-T data derived from the study of ophiolite-bearing units accreted in orogenic belts, frequently affected by HP-LT metamorphic overprint.

L'unité ophiolitique du rio Magno en Corse alpine, élément des Ligurides de l'Apennin septentrional

Comptes Rendus de l'Académie des Sciences - Series IIA - Earth and Planetary Science, 2001
Abstract The Rio Magno unit (eastern Corsica) is represented by an Apenninic-type (Internal Ligurides) ophiolitic sequence: N-MORB basalts, Lower Cretaceous Palombini-bearing limestones, Middle Cretaceous flysch. In addition, it is unaffected by HP–LT alpine metamorphism.

Sandstone Detrital Modes in the Paleogene Liguride Complex, Accretionary Wedge of the Southern Apennines (Italy)

SEPM Journal of Sedimentary Research, 1993
ABSTRACT The Liguride Complex is an ophiolite-bearing tectonic unit related to westward subduction of the lithosphere of the Neo-Tethys Ocean beneath the European margin. The complex includes a tectonic melange (the Calabro-Lucanian Flysch Unit) containing broken formations of ophiolites and related pelagic and clastic sediments (radiolarian chert ...

Ophiolites, Ligurides and the tectonic evolution from spreading to convergence of a Mesozoic Western Tethys segment

2001
The Ligurian formations, a stack of sediments deposited over an oceanic (containing ophiolites) basement in the Ligurian—Piedmont oceanic basin, provide unique records for reconstructing the opening, evolution and closure of the portion of Western Tethys that separated the European-Iberia plates to the NW from the Africa-Adria plates to the SE (Abbate ...

Gabbro-derived granulites from the External Liguride Units (Northern Apennine, Italy)

1996
In Santonian-Early Campanian sedimentary melanges of the External Liguride units (northern Apennine), slide blocks of subcontinental mantle and MOR basalts are associated with lithologies derived from the continental crust. One of these sedimentary melanges, the Mt.

Evidence of rodingitization process within Ophiolite Units (Liguride Units, Southern Apennines - Italy)

2014
New petrological data of the ophiolitic sequences from the Liguride Units (Southern Apennine Chain) are herepresented in order to investigate some rodingite dykes preserved within un-sheared low strain domains. Liguride Unitsshows indeed pervasive shear deformations, developed during subduction process reaching HP/LT conditions typical ofblueschist ...

The Liguride units of southern Lucania (Italy): structural evolution and exhumation of high-pressure metamorphic rocks

Rendiconti Lincei, 1998
The Liguride units of southern Italy represent the remnants of a subduction complex including Mesozoic to Paleogene rocks from the Neotethyan oceanic domain. In southern Lucania, a tectonic contact separates relatively high-pressure (blueschist-facies) rocks in the hanging wall from low-pressure (unmetamorphosed) Liguride rocks in the footwall. Complex

Deformation history of the Mt.Gottero Unit (Internal Liguride Units, Northern Apennines).

1991
The Mt.Gottero Unit (Internal Ligurid Units, Northern Apennines) displays a thick sedimentary sequence ranging in age from ?Late Jurassic to Paleocene p.p. interpreted as sedimentary cover of the Jurassic ophiolites. This unit is characterized by a complex structural history due to superposition of four folding phases (D1-D4) associated with minor ...

Small scale heterogeneities in MORB mantle: insights on pyroxenite-peridotite association from External Liguride ophiolites (Italy).

2011
The occurrence of mafic layers in peridotites constitutes an important compositional heterogeneity in the mantle, and their role in mantle melting and basalt generation is currently debated (e.g. Hirschmann &Stolper, 1996; Salters & Dick, 2002).

Pyroxenites in peridotites from External Liguride ophiolites (Italy): Insights on small scale heterogeneities in MORB mantle

2011
The occurrence of mafic layers in peridotites constitutes an important compositional heterogeneity in the mantle, and their role in mantle melting and basalt generation is currently debated. We present field, chemical and isotopic data on pyroxenites and host peridotites from the western peridotite massifs of the External Liguride ophiolitic Units ...
