Ancient geology could insulate Iran’s nuclear centrifuges under Pickaxe Mountain from bombing

Head Of State Donald Trump has restored risks to bomb Pickaxe Hill, a website near Iran’s Natanz nuclear enrichment site where the country’s nuclear centrifuges may sit in subterranean passages.

But high as the geology of the Strait of Hormuz offers Iran a slim canal to strangle international profession, the geology of the hill, known in Iran as Kuh-e Kolang Gaz La, gives powerful security for nuclear tools. And both have the very same beginning in a large accident between continents.

Pickaxe Hill remains in central Iran, regarding 77 miles north of the city of Isfahan. It is inland from the nation’s most famous range of mountains, the Zagros Fold-Thrust belt, which leaves the coast of the Persian Gulf in lengthy creases. The fold-thrust belt, and the associated mountains, are the outcome of the Arabian Plate colliding with the Eurasian Plate. This crash additionally formed the Strait of Hormuz right into a slim passage, prone to Iran’s control.

The beginning of Pickaxe Hill starts previously in the procedure of this collision. The ocean that initially divided both plates, the Neo-Tethys, subducted under the Eurasian Plate like a conveyor belt, bringing the Arabian Plate right into its contemporary placement. And that is where Pickaxe Mountain and its neighbors, which are part of the Urumieh-Dokhtar Magmatic Arc, come from.

“It’s generally a volcanic arc over a subduction zone,” states Richard Pedestrian, a teacher of tectonics at the College of Oxford, that has studied in the area.

When nautical crust dives below a continent, the water-enriched rock it brings causes melting, producing magma. And this magma makes its method to the surface in the type of volcanoes. Contemporary subduction zone volcanic arcs can be located in Alaska, where the Pacific Plate subducts under the North American Plate, developing the highest possible focus of energetic volcanoes in the united state And Mount Saint Helens in Washington State is the outcome of the Cascadia subduction zone, where the Juan de Fuca Plate dives below The United States and Canada. The Andes Hills in South America are populated with volcanoes that are the outcome of the Nazca Plate subducting under South America’s continental crust.

Pickaxe Mountain and its surrounding optimals are no longer active: subduction halted in the region around 30 million years back, when the Neo-Tethys Sea closed and the Arabian and Eurasian Plates butted together. But further into southerly Iran and surrounding Pakistan, there are still active volcanoes as a result of proceeding subduction in the Arabian Sea.

The mountain is made of a difficult volcanic rock called andesite, grouped through limestone that was set beside the long-lost Neo-Tethys. Andesite obtains its name from the Andes, where the same rock appears for the same geological factors. On the Mohs range of hardness, which ranges from 1 to 10, andesite is a 7, similar to quartz and more immune than a steel nail.

Pickaxe Mountain is near Iran’s Natanz Nuclear Complex, where a surge in July 2020, perhaps caused by a concealed Israeli assault, created severe damage to the country’s nuclear program. The center was attacked once again in 2021

In 2020 Iran began digging tunnels 300 -plus feet below Pickaxe Mountain to replace the centrifuge setting up facility that was damaged at Natanz, according to the Institute for Science and International Security The difficult andesite provides a 5, 275 -foot guard for these passages, providing extra safety. The united state “bunker buster” bomb GBU- 57 Huge Ordnance Penetrator can penetrate a few hundred feet via relatively soft material, such as earth and clay, however likely only a few lots feet via more challenging rock

According to the Institute, an attack would require to target weak, human-made points, such as air flow shafts or tunnel entrances, to damage any kind of equipment hidden listed below. This was the technique utilized throughout June 2025 battles at Natanz and a close-by nuclear site called Fordow that are believed to have broken devices such as centrifuges. Iran’s highly enriched uranium is thought to be sealed in underground tunnels that are buried under debris from air raid.

Iran has actually not accepted the International Atomic Energy Agency in allowing nuclear website assessments because the June 2025 strikes, however the nation is not thought to have developed a nuclear weapon
