Drilling for Iron

Posted by
Steve Rice (Olympia, United States) on 30 January 2014 in Landscape & Rural.

In 1891, the chief geologist for the U.S. Geological Survey concluded the crater was caused by a volcanic steam explosion. However, in 1903, mining engineer Daniel Barringer suggested the crater was caused by an iron meteorite. He staked a mining claim to the area surrounding the crater and began drilling in the crater floor to find the large iron meteorite he believed was buried under it. Exploration went on for 26 years until money ran out.

The reason no large iron deposits were found is because the asteroid was largely vaporized or melted into tiny pellets by the extreme heat and shock of the impact. The energy released is estimated in the 10 to 20 megaton range.

A few large fragments broke off, probably before impact, and landed a few miles away. The largest of these is at Meteor Crater.

Here, we see the cylindrical boiler and other machinery, used in drilling, next to the drill site. The flag on the fence is 6 feet X 3 feet (1.8 meters X 0.9 meters) and is barely visible to the unaided eye from the rim.

Fortunately, the meteorite did not hit the city. An interesting commentary.

Did they find pieces of meteorite iron ? Thanks for this explanation.

30 Jan 2014 8:26am

@Veronique: Yes, they found iron in two forms. One was tiny pellets of melted iron created by heat of the impact. The second was good sized chunks that probably broke off the meteorite before impact and landed a few miles away from the crater. The biggest of these is at the visitors center at Meteor Crater. You'll see it in a couple of days.

Incredible view from on high - we can imagine a future meteor strike of such force.

I had to zoom in several times in order to spot the flag. Thanks for suggesting that. The description of the search was very interesting and informative.

Beautiful textures captured in this shot! The flag sure helps establish the grand scale seen here. Thank you also for the informative background.

great info to go with this interesting shot! so he was looking not for the pot of gold at the foot of the rainbow, but for the ton of iron below the meteor ... ;-)

Baldwin Vandewalle from Bejuma, Venezuela

What most catches my attention is the huge crater created maybe by the blast pressure, because no meteorite was found on the site ... Very interesting image and fabulous explanation !!!

30 Jan 2014 11:44pm

@Baldwin Vandewalle: Yes, the blast was equivalent to a 10 - 20 megaton nuclear explosion. The crater and rim were formed in an instant. A pressure wave radiated out in all directions for some distance destroying everything in its path. Also, molten iron and rock were falling like rain all around the crater. It would not have been a pleasant place to be.

wow Steve, This is a fantastic shot in large detail !! Very interesting and great text !!
