Megasutures

Megasutures

Megasutures include orogenic zones and associated sedimentary basins. During the formation of a megasuture, the compressional tectonic regimes associated with the subduction zones are predominant. Extensional tectonic regimes and development of sedimentary basins play, also, an important role.

A megasuture can be considered as a suture created by collision between :

Continent - Continent or Continent -Volcanic arc

with a more or less important mobilization more of the substratum granito-metamorphic.
