The deformed rocks of Iran are formed due to strong mountain ridges and valleys in the Greater Caucasus mountain range, southwest of the Caspian Sea. Between 10 million and 50 million years ago, its growth was marked by sedimentary layers crushed during the first impact between the Arabian and Eurasian tectonic plates. The vividly coloured rocks produced by the sedimentary layers gathered over millennia range in tone from terracotta to greenish to bluish. Using satellite pictures, NASA’s Jet Propulsion Laboratory and Earth Observatory have shown how the landscape tended to cluster over time. One image depicts the different strata layers, vegetation, and the Zanjan-Tabriz freeway linking Tehran and Poznan. Interestingly, another image is of the Qezel Ozan River, which provides agricultural water in the region. The region is still converging, and fresh research suggests that a slab of oceanic crust is being shredded beneath Iraq and Iran. Iran’s Folded Rocks Expose Arabia-Eurasia Tectonic Collision According to reported NASA experts, a tectonic clash between the continents — known as Eurasia and Arabia — crunched these vividly hued strata of …
