12 Amazing Earth scars



Our planet is covered with pockmarks so deep that they can be seen from space. Some of them were caused by the asteroid, but most of them are the result of human intervention. Below are some of the most incredible examples of scars Earth:

1. Kimberlite pipe "Mir", Russia


Quarry "The World", located in Mirny, Eastern Siberia, Russia - a huge hole left behind by the former here once quarry diamonds. Now the quarry is closed. Its depth is 525 meters (it is the fourth deep quarry in the world), the diameter is 1,200 meters. This is the second largest excavated hole in the world, after the pit Bingham Canyon (Bingham Canyon Mine).


The airspace above the quarry closed for helicopters because of incidents in which they were sucked down the downflow.


Quarry "Peace" was the first and largest diamond mine in the Soviet Union. Its development lasted 44 years, until finally, a quarry was closed in June 2001. After the collapse of the Soviet Union in the 1990s, the quarry was taken over by the Sakha diamond company, according to reports that annual profits from diamond sales exceeded $ 600 million.

2. Crater Gosses Bluff (Gosses Bluff Crater), Australia



It is believed that Gosses Bluff is the eroded remnant of an impact crater. It is located in the southern part of the Northern Territory, near the center of Australia, about 175 kilometers west of Alice Springs (Alice Springs) and 212 km north-east of Uluru (Uluru) Ayers Rock (Ayers Rock). He was named by Ernest Giles (Ernest Giles) in 1872 in honor of Henry - brother of Australian explorer William Gosse (William Gosse), who was a member of the expedition of William.


It is estimated that the diameter of the original crater was about 22 kilometers, but over time it has been blurred. Remaining recess 5 kilometers in diameter and a height of 180 meters, is now considered a remnant of the original crater, the center of which stood up over time.


Impact origin of this topographic feature was first proposed in the 1960s, the most convincing evidence to support this theory have been numerous cones, which appeared due to the cracking of the original walls of the crater. In the past, the crater were prospecting for oil, so near its center are two abandoned exploration wells.

3. Diamond mine Dyavik (Diavik Diamond Mine), Canada


Diamond mine Dyavik this diamond mine, located in the North Slave region (North Slave Region) of the Northwest Territories (Northwest Territories), Canada, approximately 300 kilometers north of the city of Yellowknife (Yellowknife). It has become an important part of the regional economy, employing 700 people, the annual revenues in the range of $ 100 million. The mine produces about 7.5 million carats (1,500 kg) of diamonds per year.


In this field study was conducted in 1992, and in 2001 construction began. Mine started to bring the diamonds from January 2003. It is related to the ice road to the airport in the Diavik having 1,596-meter runway of gravel, which regularly travel by jet aircraft such as "737".


Mine is co-owned "by Gary Winston Diamond Corporation» (Harry Winston Diamond Corporation) and "Diamond Mine Dyavika» (Diavik Diamond Mines), a subsidiary of «Rio Tinto Group». Life of the mine is expected to be between 16 to 22 years. It is located about 220 kilometers south of the Arctic Circle.

4. Meteor Crater (Meteor Crater), United States



Meteor Crater is a meteorite impact crater, located about 69 kilometers east of Flagstaff (Flagstaff), near Winslow (Winslow) in the northern Arizona desert of the United States. Because the U.S. Department of Geographic Names (United States Board on Geographic Names) usually assigns the names of geographical features derived from the nearest post office, this crater is called "Meteor Crater" from the nearest post office, called «Meteor» .


The diameter of the crater is about 1200 meters, depth - 170 meters, and it is surrounded by edges, towering at 45 meters above the surrounding plain. Center of the crater is filled with 210-240 meters of rubble, which lies on a bed of basic rocks of the crater. One of the interesting features of the crater is its square outline, which is believed to be caused by existing regional slot (cracked), formed in the layers of rock on the point of impact.


The crater is privately owned by a family Berringer (Barringer) and their companies' Berringer Crater »(Barringer Crater Company), which states that it is" the most well-preserved meteorite crater on Earth ».

5. Kimberlite pipe "Big Hole» (Kimberley Big Hole), South Africa



In the city of Kimberley (Kimberley) is an international corporation De Beers (De Beers Consolidated Diamond Mines), which owns one of the richest diamond mines in the world. Kimberly and to this day is considered the capital of the world diamond industry. When the height of the diamond rush in the late 19th century, namely in 1871, on a small hill called Kolsberg Coppi (Colesberg Koppie) diamond was found, the founders of the company started to conduct excavations there.


After just a few months after the start of the excavation, in this place desperately excavated more than 30,000 people, searching for diamonds in an area of ​​300 by 200 meters


They quickly disposed of the hill and soon plunged into the ground to a depth of 1,100 meters, to create what became known simply as the "Big Hole".


Was removed 28 million tons of mud and found 14 500 000 carats, and resulted in the biggest hole in the world and make human hand. Here was found the famous and gorgeous diamond called the "Star of Africa» (Star of Africa), weighing 83.5 carats.

6. Crater Pingalyui (Pingualuit Crater), Canada


Crater Pingalyui (translated from Inuktitut means "where the land rises") is located on the Ungava Peninsula (Ungava Peninsula), Quebec, Canada. The diameter of the crater is 3.44 kilometers. The crater is well outlined in the soil and rises 160 meters above the surrounding tundra, and its depth reaches 400 meters.


In the crater lake is Pingalyui a depth of 267 meters, it is considered one of the deepest lakes in North America. The lake is also a repository of some of the cleanest fresh water in the world. In the lake there are no open inflows or outflows, so the water is stored solely due to rain and snow, and disappeared from the lake only through evaporation. In terms of transparency, it is one of the most transparent lakes in the world, and Secchi disk is visible in it at a depth of over 35 meters.

7. Crater Tsvayng (Tswaing Crater), South Africa



Tsvayng this crater, located in the Republic of South Africa. The diameter of this astrobleme is 1.13 kilometers and a depth of 100 meters. The meteorite that formed it, believed to have been chondrite or stony meteorite with a diameter of 30 to 50 meters, and at the moment of collision with the Earth, he vanished


Zweig Title translates as "place of salt" with the Tswana language, and the crater was formerly called in English: Crater "Salt plateau Pretoria» (Pretoria Saltpan), and in Afrikaans: Crater "salt pan» (Soutpankrater). Water comes into the crater from surface water sources, groundwater and rainwater, and is rich in dissolved carbonates, chlorides and sodium.

The average diameter of the crater is 875 meters, and rise above the bottom edge of the crater 60 meters. According to scientists, the mass of the meteorite, leaving behind a crater that was approximately 50,000 tons. In the immediate vicinity of the crater were found small iron meteorites, as well as larger meteorites, known as "shale balls", round objects, consisting of iron oxide, the weight of some of them up to 250 kilograms.


The world of science has learned about the crater after it noticed during the research of aerial photography in 1947, two months later he studied at the ground, and in 1949 reported it to the publication. European name of the crater has received from its neighboring stream, which in turn was named after Robert Wolfe (early reports in his printed name misspelled as «Wolf Creek»), a geologist and a warehouse manager during the gold rush that raged in the city Halls Creek.
