This is a fantastic Impactite Fallback Breccia from Germany weighing 21.3 grams and measuring 60x41x6mm. Although not a meteorite, impactites and shatter cones are directly linked to them and their impacts. The Steinheim Basin today exhibits a distinct morphological depression that is ∼110 m deep and ∼3.5 km in diameter; the height of the central uplift totals to more than 140 m. The original size of the pristine crater is estimated to be ∼3.8 km with an original depth of ∼205 m.
As this drainless morphological depression was filled by lake sediments shortly after the impact, the primary crater morphology is widely preserved. The crater rim is formed by steeply inclined and intensely brecciated Upper Jurassic limestone blocks that also contain numerous shattered chert nodules, as well as some loose blocks of the host limestone. An impact breccia, referred to as the so-called ”Primäre Beckenbrekzie” (“primary basin breccia”) and interpreted as a “fallback breccia”, is known from many drillings in the Steinheim Basin.
Mainly composed of Middle to Upper Jurassic limestones, marls, mudstones, and sandstones, the impact breccia inside the morphological depression of the Steinheim Basin is overlain by lake sediments and is obviously preserved in its original thickness and position. This piece displays very well and is a very nice size showing multiple characteristics of its origin. Would make a beautiful addition to any collection.

I ordered a Myanmar ruby of 1.85 ct. and a 1.2 ct. garnet. They processed my order the same day and the package showed up at home only two business days later. Beautiful gems, beautifully presented and excellent service. The website is a joy to peruse. I immediately ordered half a dozen more for a birthstone project. The best source i found for stones in Canada. Thanks Laura & Jean!
Très belle pièce. Je commence à collectionner les météorites et cette pièce est peu dispendieuse et va enrichir ma collection. Expédition rapide et excellente communication avec les gens de Canagem. AAA+++
It wasn't until I got a new UV light that I was able to see the amazing colour of this flourite. The specimen is very attractive in natural light, and crazy beautiful under 254nm UV! I love it!
