Hallo Karl, Ich selbst habe auch schon einige Impaktkrater selbst besucht. Das bild vom Tabun Khara Obo-Krater ist wirklich super! Leider ist ja gutes Bildmaterial von den abgelegenen Impaktkratern auf der Erde nur sehr schwer bis gar nicht im Netz zu finden. Meines Wissens ist Dein Bild hier auch das einzige echte Gelände-Bild von Tavan Har im Netz. Wenn Du magst, kannst Du es ja mal Jason Hines von der "Earth Impact Database" senden - dann wird das Bild sicherlich auf der Kraterseite eingebunden werden.

Sag mal: Hast Du eventuell sogar Impakt-Steine von Tavan Har mitgebracht???

Viele Grüße aus Stuttgart Martin

Hello Martin. Despite my German-sounding name, I live in the U.S. and my German is very poor... so you will have to suffer through my email written in English (sorry).

Thanks for your message about the Tabun Kara Obo Crater. I will send the photo to the folks at the Earth Impact Database. I personally did not bring any of the rocks back from the crater, but one of the students who I was working with did, He wrote a senior thesis at Colorado College on the geology of the impact structure. However, that was in 2004. I'm not sure what has happened to him or the samples since he graduated. You can read a short version of his thesis that he published with the Keck Geology Consortium (which funded our research-educational trip to Mongolia at the following web site:

I spoke with Christian Koeberl - Univ. of Vienna, at the GSA meeting this past October and he told me that he has a Mongolian student doing research on the Tabun Kahara structure and that they might drill it next summer. I'm sure you could get more info from him. His web site is:
