Discover the fascinating world of salt domes and salt glaciers found in the majestic Zagros Mountains of Iran. In this video, we explain in simple and easy language how these amazing geological structures are formed.
Salt domes are large mushroom-shaped landforms created when deep salt layers push up through heavier rocks. Over millions of years, they break through the surface and even flow down slopes as salt glaciers, similar to how ice glaciers move. You’ll also learn about salt caves, including the world’s longest salt cave, and how salt affects the shape of the Earth’s crust.
We’ll explore:
What salt domes and salt glaciers are
How they are formed
The three types of diapirism: active, passive, and reactive
The role of tectonic activity in the Zagros Mountains
How salt domes can trap oil and gas

00:00Salt domes and salt clashes are unusual natural formations found in the Zagros Mountains of
00:07Iran.
00:08These amazing landforms are made from salt that slowly rise through the Earth's layer
00:14over millions of years.
00:16Salt domes are round, mushroom-shaped hills, made when salt buried deep under the ground
00:22pushes upward through the layers of rock.
00:24Salt is lighter than most rocks, so it moves up, forming a dome shape on the surface.
00:30In the southern part of Zagros Mountains, these are more than 130 salt domes.
00:36These have played a big role in shaping the landscapes of the mountains, which are one
00:40of the world's best examples of folded mountain systems.
00:45Salt glaciers are slow-moving flows of salt that come out of salt domes and spread downhill,
00:51similar to how ice glaciers move.
00:54This happens when the rising salt reaches the surface.
00:57Because salt can bend and flow under pressure, it moves like a thick liquid.
01:02The term salt glacier was used because these salt flows behave like real glaciers made of
01:09ice.
01:10A rising column of salt, called a diaper, feeds the salt glacier.
01:15These glaciers are made of salt, gypsum, anhydrite, and clay.
01:20Besides dorms and glaciers, there are also salt caves, including the world's longest salt
01:26cave, over 6.4 kilometers long in Namakdhan Mountain.
01:30Salt valleys sink holes in salt springs.
01:34Salt forms deep underground.
01:35Over the time, layers of rock and dirt build up above the salt, becoming heavier and more compressed.
01:41But salt keeps the same density.
01:44Because of the difference in density, salt begins to rise.
01:48When salt breaks through the surface, it can form a salt glacier.
01:52There are three main ways that can salt rise.
01:56The active diaperism, when the salt rises and pushes the layers above it upward.
02:02Precessive diaperism, salt stays near the surface and layers built around it.
02:08Reactive diaperism, due to the stretching of the Earth's crust, the upper layer becomes
02:13thin and weak, letting salt rise.
02:16Salt glaciers are an important part of salt.
02:19Tectonics, which is the study of how salt shapes the Earth's crust.
02:24Salt moves when pressure is uneven or when other geological forces act on it.
02:29The movement depends on the strength of the rock above the pressure from the salt below.
02:34The Zagros Mountains are in a very active tectonic zone.
02:38The Arabian and Euro-Asian plates are slowly pushing against each other.
02:43This movement helps salt layers rise and form domes and glaciers.
02:48Salt domes are also important in the search for oil and gas.
02:52When salt pushes up, it bends the rock layers above it.
02:56This can trap oil and gas, making these places good for drilling and energy production.
03:01So that's why salt domes are very valuable in the oil and gas industry.
