  Meteor Crater - Wikipedia, the free encyclopedia
The crater is somewhat misnamed, as it was actually excavated by a meteorite, not a meteor.
Barringer and his partner, the mathematician and physicist Benjamin C. Tilghman, documented the evidence for the impact theory in papers presented to the U.S. Geological Survey in 1906 and published in the Proceedings of the Academy of Natural Sciences in Philadelphia.
Barringer's arguments met with skepticism, as there was a general reluctance at the time to consider the role of meteorites in terrestrial geology.

 Impact crater - Wikipedia, the free encyclopedia
An impact crater (impact basin or sometimes crater) is a circular depression on a surface, usually referring to a planet, moon, asteroid, or other celestial body, caused by a collision of a smaller body (meteorite) with the surface.
In the center of craters on Earth a crater lake often accumulates, and a central island or peak (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake.
Few underwater craters have been discovered because of the difficulty of surveying the sea floor; the rapid rate of change of the ocean bottom; and the subduction of the ocean floor into the Earth's interior by processes of plate tectonics.

The Barringer Crater, also known as the Meteor Crater, is a famous impact crater created by a meteorite, located about 55 kilometers east of Flagstaff in the northern Arizona desert (USA).
Barringer's company, the Standard Iron Company, conducted research on the crater between 1903 and 1905, and concluded that the crater had indeed been caused by a violent impact.
Barringer and his partner, the mathematician and physicist, presented their first papers to the U.S. Geological Survey in 1906, outlining the evidence in support of the impact theory.

After making a mining claim, Barringer and a group of investors started drilling in the crater for a large mass of meteorite he believed to be in the bottom of the crater, and the commercial profits that would be made from its minerals.
Barringer should be recognized for going against the currant science of his day and believing in the true crater's origin.
Barringer's interest was in mining the crater for a meteorite he believed to be a the bottom of the crater and the nickel content the meteorite would have.

Complex craters have a raised central peak surrounded by a trough and a fractured rim.
Craters that have been obliterated by erosion over thousands of years, leaving only a circular scar on the earth's surface, are called astroblemes.
Craters are also commonly formed at the surface opening, or vent, of erupting volcanoes, particularly of the type called cinder cones, where the lava is extruded rather explosively.

Craters are typically caused by meteorite impacts, although some are caused by volcanic activity (see volcano for more on these).
In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake.
Daniel Barringer was one of the first to identify a geological structure as an impact crater, the Barringer Meteorite Crater (or the "Meteor Crater") in Arizona, but at the time his ideas were not widely accepted, and when they were, there was no recognition of the fact that Earth impacts are common in geological terms.

 Meteor Impact Craters
Craters are bowl shaped depressions made when a meteorite collides with a planet or moon.
This peak is caused by the surface's attempt to rebound from the impact.

 Terrestrial Impact Craters
In larger craters, however, gravity causes the initially steep crater walls to collapse downward and inward, forming a complex structure with a central peak or peak ring and a shallower depth compared to diameter (1:10 to 1:20).
The central peak or peak ring of the complex crater is formed as the initial (transient) deep crater floor rebounds from the compressional shock of impact.
Chemical, isotopic, and age studies demonstrate that the crater is the most probable source for the Ivory Coast tektites, which are found on land in the Ivory Coast region of central Africa and as microtektites in nearby ocean sediments.

The story of Meteor Crater, also called Barringer Crater, began 50,000 years ago with an asteroid roughly twice as wide as this hall hurtling to Earth at about 50 times the speed of sound.
Once the dust and debris settled, the crater sat quietly for tens of thousands of years as the Arizona climate gradually grew drier, helping to preserve evidence of the impact.
When mining engineer Daniel Barringer first argued in 1906 that an impact formed the crater, he noted that the meteorites and other rock debris around the crater were randomly mixed together in one layer.

Recognizing that the Crater is a unique natural land-mark of great scientific importance, strong public interest, and significant educational value, it is the company's long-held policy to maintain the property in as nearly a natural state as possible and to ensure appropriate and controlled access to it by the general public.
Barringer's attempts to convince the scientific community of the truth of his theory were, of course, intimately connected with his growing need to raise capital for continued drilling.

Barringer Meteor Crater, AZ The Barringer Crater is a gigantic depression in the sandstone desert of Northern Arizona.
The crater was created about 50,000 years ago by a meteorite smashing into the Earth that was 150 feet across, weighing 300,000 tons, and travelling at about 40,000 miles per hour.
The meteorite was primarily made of nickel and iron, as evident by the abundance of nickel-iron meteorites found in or around the crater.

Daniel Barringer graduated from Princeton University in 1879 at the age of 19, and in 1882 graduated from the University of Pennsylvania's Law School.
Upon hearing of the existence of the crater and the meteoritic iron, Barringer became convinced that the crater was of meteoritic origin.
Barringer died of a heart attack on November 30, 1929, shortly after reading the very persuasive arguments that no iron was to be found.

Secondly, any crater on dry land would be at the mercy of the elements, and should there have been collisions with cometary debris, or asteroids, in the Amazon Basin, say, then vegetation would without doubt obscure them in a very short time indeed.

I am happy to hear Barringer crater was surrounded by sources of salts that could flow into the crater.
Since the Barringer crater is only 50,000 years young, it would be interesting to know how much more concentrated the salts are in the crater.
In an area with no surface water egress like Barringer Crater, concentrated salt deposits do form as water evaporates, and trying to backcalculate the relative salt concentration at multipple source beds would be difficult.

Drilling in the crater has shown that the rocks forming it have been shocked by an explosion, and are not volcanic in origin.
The absence of such a buried object at the Barringer crater in Arizona caused confusion as to its origins for many years, although in that case traces of the original iron asteroid have been found.
As the Tswaing crater is slightly smaller than the Barringer crater, we shall assume that the energy of the explosion there was equivalent to 10 million tonnes of TNT.

 EO Newsroom: New Images - Barringer Meteor Crater, Arizona
Barringer Crater, also known as “Meteor Crater,” is a 1,300-meter (0.8 mile) diameter, 174-meter (570-feet) deep hole in the flat-lying desert sandstones 30 kilometers (18.6 miles) west of Winslow, Arizona.
It shows the crater much as a lunar crater might appear through a telescope.
The ejecta blanket around the crater appears somewhat lighter than the surrounding terrain, perhaps in part due to its altered mineralogic content.
