Hi Friends,  Offered for sale is a Meteorite Fallback Breccia Briquette From Missouri Astrobleme W/Fossils 117 Grams. This is another unique specimen with protruding fragments, grainy texture, and many excellent micros and fossils in sort of a briquette shape. This is a Missouri round rock briquette(haha) which was probably formed from green shale mud shot up gathering minerals from a meteorite strike near Weaubleau and Osceola Missouri when ocean still covered the territory 340 million years ago. These stones are a conglomerate of rock particles, fossils, micro tektite, impact debri, and most likely green shale yolk inside. Dark glassy micro-tektite have been viewed in many of these round rocks (high magnification is best), and these stones are tektite-like shape objects as well. There may even be some particles of granite in this; blown up from the bottom of the meteorite entry. Some of these specimens have green stone speckles (tektites?) in them. Each one of these round rocks is a unique specimen affected in different distance and angles to the meteorite impact. It could be said this breccia was formed while flying through the air. The Weaubleau Structure is the 4th largest impact site in the USA dating around 340 million years since impact and has a 12 mile circular eroded crater area. The probable meteorite hit in a location that was once Mississippian Era Ocean, was sealed with millions of years of limestone formation and may be one of the only preserved ancient meteorite sites in the World. Through more recent erosion stones which may have been result of or affected by the ancient impact are being found basically un-eroded with a little chalcedony seeped in. There are still many mysteries in scientific information about the Osceola Weaublueau Impact Structure. Much information can be gathered from many sources internet on this subject. The stone pictured is the one you will receive. *This stone weighs 117 grams and measures about 61mm by 55mm by 35mm. **USA FREE SHIPPING  ***INTERNATIONAL- Canada, Mexico, Europe, Australia, etc.-shipping is $10 for the 1st item, and free (combining single invoice in shopping cart before payment) shipping for additional items purchased after the first item won or ordered in cart.  Buy with confidence, I am a responsible shipper.
