Scientists explain Italy's 'unzipping' crust via delamination process

Geologists led by Stefano Tavani propose that a zipper-like peeling of the lower crust explains the Apennines' paradoxical geology.

What to know

  • Tavani's team proposes that delamination—a zipper-like separation of the lower crust sinking into the mantle—explains why the Apennines simultaneously compress and extend.
  • The migrating delamination front, or 'hinge,' moves toward the Adriatic foreland, solving a 20+ year geological puzzle about contradictory surface movements and earthquakes.
  • The process began around 2 million years ago when the major phase of extension that opened the Tyrrhenian Sea ended, yet paradoxical deformation of the mountain range continued.

    Tavani's team proposes delamination as explanation for Apennine paradox

    Geologists led by Stefano Tavani of the University of Florence present research suggesting that Earth's crust is 'unzipping' beneath Italy through a process called delamination. The lower crust and lithosphere peel away and sink into the mantle along a single migrating front—like a zipper—moving toward the Adriatic foreland, explaining why the Apennines experience both compression and extension simultaneously.

    “Earth's crust is 'unzipping' under Italy, producing the strange geology on the land above. It's a process known as delamination, in which the dense lower crust and attached lithosphere peel away from the crust above and sink into the mantle.”
