VERY LARGE Ries Germany FLAEDLE Impact Glass Bomb IMPACTITE, 328-GRAM (11.5-OZ.)

Description

Offered here for your very kind consideration is a complete individual “impactite,” a mixture of vaporized asteroid, Earth rock and soil profoundly affected by the pressure of the asteroid impact. Specifically, it is an impact crater glass bomb known as "Flädle," a German word for a local pancake or flatbread, which they somewhat resemble. Strike it and it gives a noise like struck glass. It formed when a large asteroid or comet struck Earth in what is now part of Germany during the Miocene, some 14.4 ± 0.1 million years ago.
This classic specimen resembles a twisted mat of melt. It is 11.0 x 9.5 x 5.0-cm (about 4¼ x 3¾ x 2-inches) and it weighs 328-grams (11.5-oz.). I purchased it decades ago from Peter Bockstallar, well-known collector and occasional seller of quality impactites
The pressure of impact vaporized where it struck leaving a large crater, most commonly referred to today as the Ries Crater. Its original diameter is estimated to have been 24-kilometers (15-miles). Beneath the crater, rocks were smashed to the depth of many kilometers (miles). Many were extremely compressed and partially melted. Shattered rock, dust, and ash were hurled up, only to fall back within the crater and surrounding
it
as layers of "Bunte Breccia"
. Partially molten rock was hurled up into the stratosphere and rained back down, becoming aerodynamically sculpted in the process, falling atop the previously deposited Bunte Breccia. These specimens of Flädle somewhat resembles volcanic bombs.
I’m selling my extensive collection! This very fine specimen is among my last and certainly the largest. As you can plainly see, it has an abundant amount of fascinating melt and will have you rotating it around and around in an attempt to fathom the forces involved in its formation.
I will include a roughly 5.0-cm (2-inch) paper label. I will ship this hard unbreakable specimen wrapped in bubble pack anywhere within the USA via First Class. I can certainly add it to other auctions of mine you may have won and send everything in one carton to save you the cost of my sending multiple packages.
