Paradise for geologists

Welcome to incredible Iran: Paradise for geologists!

Give us your hands until to familiar with beauties of Iran. Geological history of Iran is full of events, created widespread volcanic, magmatic and metamorphic outcrops. Thick stratigraphic sequences are naked across the country.

Our country hosts so many major faults, long anticlines and perched synclines, the beauty phenomena for structural geologists. Iran also is the country of Quaternary deposits and landforms extend from mountains top (glaciers) to the hill slope (alluvium) and from there to the lowlands in central Iran where the fascinated deserts, salt lakes, sand dunes and Yardangs have created a very attractive landscape for geologist and geomorphologists.

West of Iran is domain of karstic features, such as beautiful caves and large sinkholes which are formed during the last glacial stage.

Landslides are frequent in everywhere, including the Seimareh landslide with kilometers in length and width, well known as the largest landslide in the world.

The Zagros Mountain is located in the south and southwest of Iran. The famous structural – sedimentary zone contains the largest oil and gas reservoirs.

Our international guests can see the continuous stratigraphic sequence with several kilometers thick from Jurassic up to Pliocene, bare and easily to investigations.

The south of Iran also is the best place for visit unique salt domes, mud volcanoes and recent reefal limestone.

Iran also has an exceptional geographic and climatic conditions. The difference temperature between north and south sometimes reaches to 30 centigrade.

In the North, the shore line of the Khazar Sea, as the largest lake in the world, and its surrounding area with mountainous forest, are the attractive place for millions of tourists in all seasons. In this region, the natural beauties are in your path.

Toward central and southern parts of Iran can enjoy the magnificent and beautiful deserts, Kavirs as well as salt lake and playas have extended far away.

Damavand, Sabalan and Sahand as the most famous volcanoes of Iran and their young volcano-clastic rocks welcome to all volcanologists throughout the world.

There are so many Geo-parks and Geo-sites that increase your familiar with other natural beauties of Iran.

All attractions with low cost traveling, unbeatable security and hospitable people will excite you for travelling to Iran again and again.

“ZaminGasht” is a window to meet you the natural beauty and geological phenomena of Iran. We have numbers of Iranian experts in all branches of geoscience who can identifying natural beauty of Iran to all international geoscientists and geo-tourists.

Chahkuh Gorge

Chahkuh Gorge is located in the northwest part of the Qeshm Island, near West Chahu village. This Geosite is a good example of running water erosion and formation of a canyon form valley. The erosion was the secondary parameter to create this valley; it was happened along a deep joint and crack resulting the Salakh Anticline movement. So the primary parameter was the structural forces.

Chahkuh geological formation are inside the Salakh Anticline, near the salt dome appearance location. Anticline is a ridge-shaped fold of stratified rock in which the strata slope downward form the crest. Resulting the internal pressures and stretches many cracks, joints and faults appear on the anticline flanks those are the weakest points toward erosion. Chahkuh Gorge is a primary joint developed by erosion.

There is another gorge perpendicular to the main gorge; also created by the same mechanism. In general, anticlines and unstable locations so there always appear many faults and joints.

There is variety of shapes and form namely orbicular, dished, oval and linear on the walls or floor of the gorge all created by the powerful running water after raining. In some cases pieces of rock moves fast and circular inside the gorge and curves the surface to create wells and bowl shape holes (pot-hole).

Geological formations in Chahkuh is impermeable (Aghajari Fm.); it causes rain water to run over the surface. Local people invented a genius innovation using this feature; they dug some shallow wells in the surface to reserve rain water and use it. While Qeshm Island is an extremely dry area, water is worthy and important there; that’s why this innovation is very interesting and practical.

One of the main reasons to name this place as Chahkuh (barrow-well) is because of the water wells in this area and the usage of them by local people in years.

Chahkuh Gorge is created inside alternation of sandstone and marl formation of Aghajari – Mishan (Miocene-Pliocene). This formation comprises of cream color thin bedded limestone that gets thicker on the top part. Over the limestone part, soft sandstone bed appears. The sandstone consist of carbonate particles so it is not very resistance to the erosion. There are some parameters which affects the resistance of the sandstone and creating erosion forms: context and existence of vertical joints.

Badab-e Surt

Badab Soort (Persian: باداب سورت‎‎) is a natural site in Mazandaran Province in northern Iran, 95 kilometres south of the city of Sari, and 7 kilometres west of Orost village. It comprises a range of stepped travertine terrace formations that has been created over thousands of years as flowing water from two mineral hot springs cooled and deposited carbonate minerals on the mountainside.

Badab is a Persian compound of Bād “gas” + āb “water”, translating to “gassed water”, referring to the springs’ waters being carbonated mineral waters. Soort is an old name for the Orost village and a Persian word meaning intensity.

Badab Soort’s springs are two distinct mineral springs with different natural characteristics, located at 1,840 metres above sea level. The first spring contains very salty water that gathers in a small natural pool; its water is considered to have medicinal properties, especially as a cure for rheumatism and some types of skin diseases and skin conditions. The second spring has a sour taste and is predominately orange mainly due to the large iron oxide sediments at its outlet.

Badab Soort’s terraces are made of travertine, a sedimentary rock deposited by flowing water from the two distinct mineral springs; they were formed during Pleistocene and Pliocene geological periods. When the water, supersaturated with calcium carbonate and iron carbonate, reaches the surface, carbon dioxide degases from it, and mineral carbonates are deposited. The depositing continues until the carbon dioxide in the water balances the carbon dioxide in the air. Iron carbonate and calcium carbonate are deposited by the water as soft jellies, but they eventually harden into travertine.

As a result, over the course of thousands of years the water from these two springs emanating from the mountain range have combined and resulted in a number of orange-, red- and yellow-colored pools shaped as a naturally formed staircase. The surrounding vegetation to the north consists of pine forests while to the east it mainly consists of short trees and shrubs; and rock quarries can be seen to the west of the site.

Iran is the paradise for geologists

Iran is the paradise for geologists. This sentence was said by International geologists, after visiting Iran and see the natural beauty and geological phenomena. Iran is due to being in the Alpine Himalayan orogenic belt and collision zone of the Eurasian – Gondwana supercontinents, has a complex and interesting geological history. 

Tectonic movements, compression and tensile forces, uplift and erosion, in a vast land with low vegetation,have created the beautiful and eye-catching landscapes of geological phenomena.

Deserts, plains and mountains, high plateaus, rivers and waterfalls, seas and lakes, faults, folds, salt domes, landslides and mass movements, volcanoes and associated structures, rocky outcrops, slopes and alluvial plains, beautiful caves, numerous mines, fossils and minerals varied, part of Iran’s natural and geological beauty.

You probably knew Iran in the past, with it’s magnificent and the greatness monuments, The great and monumental history, and kind and hospitable people. So give us your hands until you’re familiar with other beauties of Iran. There are many Geo Parks and Geo sites in Iran that will increase your enjoyment of travel to this country. We show you the unique natural beauty in Iran, that Like it less seen.

The hottest place on Earth, the largest lake on Earth, the biggest landslide in history, one of the world’s largest water cave, the highest volcano in Asia, one of the world’s largest salt lake, one of the world’s tallest stone wall, one of the largest deserts in the world, beautiful and unique salt domes, one of the unique stone cities of the world, and other beautiful landscapes are all in Iran.

All the attractions with low cost traveling, unbeatable security, and hospitable people, have turned Iran into an attractive destination for travel.

“Zamin gasht” is a window to meet you the natural beauty and geological phenomena of Iran. We have a number of Iranian geologists that are trying to identified beautifully of Iran’s geology to tourists and Geo-tourists in all over the world.
