This impact breccia was found in the area of the village of Fuendetodos near the center area of this large multiple impact structure

Single large plates or "books" of biotite can grow to considerable size and can make impressive mineral specimens

This is a must have 54 gram Impact Vesicular Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in Southwestern France

Here we have for you a nice looking individual cut fragment of a Sahara Desert NWA unclassified meteorite weighing 107 grams

Its dimensions are 75x69x40mm

Kofelsite Impact Myth | Grey Melt Rock | 22.3 grams | Köfels Structure | Austria | SO24 Natrolite This impact breccia was foundThis is a 22. 3 gram Grey Melt Rock from the Kfels Structure, Austria. It measures 38x22x21 mm. The specific origin of kofelsite rocks is uncertain & debated. The rocks are found in a landslide deposit in western Austria. Researchers have suggested that the landslide was impact triggered. The kofelsite samples in the landslide deposit thus may be impactites (fused rocks from the heat of impact). Some workers have suggested that the rocks are
