Scientists Discover Two Enormous Tears in a Tectonic Plate Beneath Iran
Scientists have discovered two massive tears in the Arabian tectonic plate beneath Iran's Zagros Mountains. The study, published in Nature Geoscience, suggests these ruptures are caused by the collision of oceanic and continental crusts, providing new insights into tectonic plate dynamics.
Why it matters
Understanding these geological shifts helps scientists better predict seismic activity and understand the evolution of the Earth's crust.

They are constantly moving, though, and across millions of years, that movement leads to some globally significant shifts in the landscape.
Researchers led by a team from the Chinese Academy of Sciences have now found extensive evidence of two giant tears in a tectonic plate called the Arabian Plate, underneath southeastern Iran.
The tears are being caused by different rock densities. One part of the plate is what's known as an oceanic slab and was once part of the ancient Neo-Tethys Ocean.
The basalt rock here is heavier and thinner and is being pushed under a neighboring plate (the process of subduction).
