Where do tektites found in the Philippines come from? I'd really like to know your opinion. I've read they're from an impact crater in Khazakstan. A picture from a small collection that I have may be viewed at http:macrocosm-magbook.blogspot.com/ Look for the article in the archives. It's one of the first. You can then follow the links for individual pictures.
