The Mediterranean region traditionally represents a difficult but intriguing study area for plate tectonic modeling. These pages illustrate, through reconstruction maps, animations and few comments, the main results of a new quantitative model of the tectonic evolution of the Tethyan realm since Early Jurassic. Details of this model can be found in the following paper [in review]:

Schettino, A., and C. R. Scotese, Global kinematic constraints to the tectonic history of the Mediterranean region and surrounding areas during the Jurassic and Cretaceous, in: Rosenbaum, G. and Lister, G. S., Reconstruction of the evolution of the Alpine-Himalayan orogeny, Journal of the Virtual Explorer, 2002.

A QuickTime(TM) animation illustrating the modeled pattern of sea-floor spreading and the formation of new plate boundaries during the Jurassic and the Cretaceous can be found here (Warning: 4432 KB).

Reconstruction at 200.0 Ma (Lower Sinemurian)

This is the assumed starting configuration of the continents around the Tethys at the beginning of the Jurassic.

Reconstruction at 172.0 Ma (Upper Bajocian)

- Onset of seafloor spreading in the Central Atlantic;
- Rifting in the Atlas region;
- Collapse of the Pindos Ridge;
- Subduction of Triassic Tethys under Sanandaj-Armenia

Reconstruction at 170.0 Ma (Upper Bajocian)

- Spreading in the Liguride Ocean;
- Spreading in the Alpine Tethys;
- Formation of a transform boundary between Iberia and Morocco

Reconstruction at 154.3 Ma (Chron M25 - Upper Oxfordian)

- Spreading in the Eastern Tethys and formation of the Vardar plate;
- Drifting of Northern Turkey towards Eurasia;
- Formation of the Inner Tauride Ocean

Reconstruction at 147.7 Ma (Chron M21 - Middle Tithonian)

- Iberia separates from North America;
- Strike-slip motion along the North Pyrenean Fault

Reconstruction at 139.6 Ma (Chron M16 - Upper Berriasian)

- Iberia remains attached to Northwest Africa;
- Extinction of the Liguride Ocean spreading center

Reconstruction at 131.9 Ma (Chron M10 - Lower Hauterivian)

- Opening of Valais oceanic trough by separation of the Sardinia-Corsica-Brianšonnais domains from the southern French margin

Reconstruction at 130.0 Ma (Chron M9 - Lower/Upper Hauterivian Boundary)

- Convergence in the Liguride Ocean;
- Transpression at the boundary between Iberia and Africa;
- Rifting in the North Atlantic

Reconstruction at 126.7 Ma (Chron M4 - Hauterivian/Barremian Boundary)

- Transtension at the boundary between Iberia and Eurasia

Reconstruction at 120.4 Ma (Chron M0 - Barremian/Aptian Boundary)

- Seafloor spreading in the North Atlantic region;
- Collapse of the Vardar Ridge;
- Rifting in the South Atlantic region

Reconstruction at 110.0 Ma (Lower Albian)

- Seafloor spreading in the South Atlantic region;
- Opening of the Biscay Bay;
- Onset of Alpine subduction;
- A new trench forms at the southern Eurasian margin (Rodophe-West Pontides);
- Right-lateral motion along the Central African Shear Zone

Reconstruction at 83.5 Ma (Chron C34 - Santonian/Campanian Boundary)

- Compression in the Valais Trough;
- Sakarya and Kirsehir collide with Eurasia (87 Ma);
- A new trench is established South of the Sakarya-Kirsehir block;
- Subduction of the Inner Tauride Ocean;
- Northwest Africa and Iberia rotate clockwise with respect to Northeast Africa;
- Small component of convergence in the Liguride Basin

Reconstruction at 74.3 Ma (Chron C33n - Upper Campanian)

- Motion of Sakarya and Kirsehir is a combination of right-lateral sliding along the trench and clockwise rotation;
- Onset of the Pyrenean orogeny;
- Upper Campanian rifting and possibly spreading in the Southern Mediterranean region

Reconstruction at 67.7 Ma (Chron C31n, Upper Maastrichtian)

- Closure of the oceanic connection between Tethys and the Indian Ocean;
- Onset of compressive tectonics between the Tauride Platrform and Arabia;
- Subduction in the Liguride Ocean;
- Right-lateral motion of Sakarya and Kirsehir with respect to Eurasia
