Possible impact crater in Switzerland?
« on: 21/01/2010 08:43:28 »
Hi,

I was got curious when I read the following article newbielink:http://www.telegraph.co.uk/science/science-news/3337909/Clay-tablet-holds-clue-to-asteroid-mystery.html [nonactive] about an asteroid that might have impacted somewhere near Kofels, Austria. I'm no Geologist, but curiosity got the best of me. I ran a search on the areas near Kofels up to the Large Hadron Site in Switzerland and found

Google Maps 46.692666,7.224884

any ideas?

Thanks!  :)

I don't think that an air-explosion would have created such a crater and the presence of shocked quartz and shatter cones within the area will confirm that it's the result of an asteroid strike.  These features only occur as a consequence of hypervelocity impacts.

Having no knowledge of this area, I have to agree with LeeE, one should look for corroborating evidence such as shocked quartz, shatter cones, breccia, etc.

Circular geomorphic features can also be created by intrusive rocks.

Actually, I was just thinking that it looked more like a big lava dome in the middle of a caldera than an impact crater.

This is produced by thrusting - only thrusting. There is no listing in the earth impact database for this and the geologic map for the area does not show any unusual structures. The nature of the Swiss is not to leave much information out. The black lines are the aprox. edges of the feature. Match the streams up with those on the plain topo map for a good match.



The closest listed impact feature is Steinheim, Germany
   
N 48° 41' E 10° 4'

The geologic community seems to be s yet unconvinced. Don't know what these people are on about.

Discover Dave - The article, when read, says there is no surface expression of the impact. Köfels is just southwest of Umhausen, Austria. Look it up on Google maps.

I also thought of it as a lava dome, but Switzerland doesnt have volcanoes right?

I agree with JimBob, the topo map certainly shows that it is a feature made by thrusting. It looked promising when viewed on top, but on closer magnification using NASA World Wind it showed all the normal features of a montain chain/range caused by thrusting.



I was really hoping the Swiss just forgot or never really bothered to check it out. Anyway, I'm still intrigued on the idea of the tablet and asteroids.

Thanks everyone for the information and insight.

SO? I have a dyslexic keyboard!   [:(!]

"Thrusting" is when a large sheet of the earth's crust is pushed on top of and over another piece of the earth's crust.

I must have a dyselxic monitor. I read it is thrusting. I was going to reply with something like "well, if you don't know by now I'm not sure I can help you", but I thought it might lower the tone a bit (as if it could actually be any lower ;D)
