The two main tectonic units of the Liguride Complex, namely the metamorphic Frido Unit and the non-metamorphic North Calabria Unit, have been sampled in this study. Results indicate that in the Pollino area the metamorphic grade show an overall decrease from the SW to the NE. The Frido Unit it is characterized by HP/LT metamorphism. The highest values of temperature (280-330\u00B0C) and pressure (11-13 kbar) were detected in the southern sector of the area. The intermediate values (T = 250\u00B130\u00B0C and P = 8-10 kbar) were observed in the central sector, whereas lowest values (T = 180\u00B120\u00B0C and P = 7\u00B10.5 kbar) were registered in the northern sector. These thermobaric conditions and the inferred geothermal gradient (? 8\u00B0C/km) are in accordance with the lawsonite-blueschist mineral assemblage shown in associated metabasite and with the presence of aragonite in the carbonate levels. Data obtained from pelites of the North-Calabria Unit indicate high diagenetic thermobaric conditions with temperatures of 110-150\u00B0C and pressures of 2-3 kbar. More in detail, temperature values of 130-150\u00B0C and of 110-140\u00B0C are obtained in the Crete Nere and the Saraceno Formations, respectively. These moderate variations in the diagenetic grade might be influenced by differences in the bulk rock composition. The wide range of temperature and pressure conditions documented within the Liguride Complex indicates that samples have been collected in different thrust sheets characterized by variable metamorphic overprint. Systematic variations in thermobaric conditions are particularly evident within the metamorphic Frido Unit, which is probably made up of some thrust sheets and/or slices derived from different portions of the accretionary wedge."@en ; prodottidellaricerca:prodottoDi istituto:CDS055 , modulo:ID8250 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA7763 , unitaDiPersonaleInterno:MATRICOLA12830 . @prefix parolechiave: . prodotto:ID203410 parolechiave:insiemeDiParoleChiave . ns11:ID26656 pubblicazioni:rivistaDi prodotto:ID203410 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID203410 .
