Middle Triassic palaeogeography of the Alpine region: a Definition of the location of the Adria-Apulia continental lithosphere. The grey area represents continental lithosphere and white oceanic lithosphere. Continuous orange lines: active rifting; dashed orange: initial rifting; red: spreading centres; green: transform faults. Ad: Adria; Ap: Apulia; Ar: Arabia; Eu: Eurasia; Ib: Iberia; NEA: Northeastern Africa; NWA: Northwestern Africa; IB: Ionian basin (which is related to the Neotethys oceanic domain). Modified from Schettino and Turco (2011), and b Definition of the four main palaeogeographic domains in the Alps: Helvetic and Penninic (Eurasia continental lithosphere at the northern margin of the Alpine Tethys Ocean), Austroalpine and South-Alpine domains (Adria-Apulia continental crust at the southern margin of the AlpineTethys Ocean). Dashed orange line represents the initial rifting of the South Penninic – Ligurian Ocean. Dashed black lines represent boundaries between palaeogeographic domains. Names of present day basement units are given for geographical reference. Modified from Pfiffner (2009)
