On the basis of comparative stratigraphic and paleontologic analysis,
supported by some key paleomagnetic data and interpretations, it is sh
own that during the Mesozoic and the Cenozoic the Eurasian continent g
rew by accretion of microcontinents. These microcontinents separated b
asins with oceanic crust from the main ocean. During the Late Cretaceo
us and the early Cenozoic the collision of the microcontinents with Eu
rasia resulted in the closure of the basins, and Meso-Tethyan oceanic
sutures originated. In the region under consideration, from the Carpat
hians to Tibet, there are two main Meso-Tethyan sutures: the Carpathia
n-Lesser Caucasus and the Afghan-Tibet suture. The above-mentioned mai
n structures also had branches, which remained as sutures of small bas
ins: the Kamennopotock, Interpontide, Nain-Baft basins and others. In
the West Carpathians the Carpathian-Lesser Caucasus suture is overlain
by a widespread Gemeric-Tatric allochton. From the West Carpathians t
he suture passes through the Pannonian basin into the Vardar ophiolite
zone and farther to the ophiolites of the Izmir-Ankara zone. Being di
splaced along the North Anatolian right-lateral strike-slip fault, the
main suture passes from the Eastern Pontides into the Lesser Caucasus
, where it is marked by ophiolites of the Amasia area, the Shirak, Boz
um and Zangezur ridges. Subsequently, it can be observed through the I
ranian Qara Dagh mountains to Lake Urumiyeh and the North Anatolian st
rike-slip fault. Being again shifted along the strike-slip fault, the
Carpathian-Lesser Caucasus Meso-Tethyan suture ends in the Western Zag
ros near the Cenozoic Neo-Tethyan suture. The Afghan-Tibet Meso-Tethya
n suture is situated in the Pamirs in the Rushan-Pshart zone. The east
prolongation of the suture has been displaced along the Pamir-Karakor
um right-lateral strike-slip fault in Tibet. West of the Pamirs this s
uture is also displaced along strike-slip faults and continues in the
Farahrud zone in Afghanistan, and than passes through the Zabol-Baluch
and Daz Murian ophiolite zones and approaches the Neo-Tethyan suture.
The paleomagnetic data allow us to reconstruct the location of those
sutures in the Late Cretaceous-early Cenozoic. If one compares the pre
sent position of the Carpathian-Lesser Caucasus and Afghan-Tibet Meso-
Tethyan sutures with the Late Cretaceous-early Cenozoic reconstruction
s of these sutures it is possible to trace the inner deformation of th
e Alpine belt. According to these data, the Carpathian-Lesser Caucasus
suture moved northwards over 1200 km ahead of the Arabian-Turkish syn
taxis with the displacement direction across the fold belt. At the bor
der of the Dinarides and Hellenides, the displacement decreases to 400
-500 km, and its direction is along the fold belt. The amplitude of th
e suture displacement increases in the Pannonian region and again decr
eases towards the Eastern Alps. The displacement of the Afghan-Tibet s
uture was > 2000 km during the Alpine deformation.
