Impactites

This is a 16.51 gram Grey Melt Rock from the Köfels Structure, Austria. It measures 43x27x13 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 frictionites (fused rocks from landslide heating).

The Köfels landslide was a huge mountain rockslide (a Sturzstrom) that occurred in the Austrian Alps about 9800 years ago near the present day village of Köfels. Some of its features mystified geologists for quite some time. One hypothesis was that it had been caused by an asteroid impact — a Köfels impact event — but more recent research has rejected the idea. This didn't stop a pair of British engineers from publishing a book that claims that a) it was an asteroid impact, b) it inspired a lot of myths, and c) it was recorded on an ancient Sumerian clay tablet.

The reason for the original impact hypothesis was the presence of fused rock. At the time, the only processes known to be able to do this were either volcanism or meteor impacts. Later research found that it can be also produced by friction and similar fused rock has been found in other large rockslides.

This specimen displays very well even if not proven to be meteorite impact related.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is an outstanding specimen of Impact Melt Glass or "Flädle" glass from the Lake Mien crater, 12 km (7.5 mi) southwest of the town of Tingsryd, Sweden. Although not a meteorite, impactites are directly linked to them and their impacts.

Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite. The term encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc.

This eroded crater is marked by a 5.5-km (3.4-mi) diameter circular lake named Lake Mien. The original crater rim is estimated to have been about 9 km in diameter before erosion. Its age is estimated to be 121.0 ± 2.3 million years (Early Cretaceous).  This Suevitic breccia with clastic matrix and melt inclusions (black) and crystalline rock clasts (gray to white) is amazingly light considering its 12.67 grams with a mass of 36x34x12 mm.   It has a unique hollow sound when you tap it.

This is an outstanding Impact Melt Glass specimen or bomb weighing 1 grams.  Its dimensions are 19x17x12 mm.  Although not a meteorite, impactites are directly linked to them and their impacts.

This Henbury glass or more specifically vesicular impactite was found in the Northern Territory of Australia. Eight miles southwest of the town of Henbury, 13 craters were found, the largest of which was 720 x 360 feet.  This impactite was formed years ago when many meteorites crashed into the earth making all those craters which produced the impact glass.

This piece displays extremely well.  It is amazingly light considering its mass.  It has a unique hollow sound when you tap it.  This Australian find is very well shaped and preserved. These pieces are becoming more difficult to acquire so this is a good time to get a fine specimen.  Would be a beautiful addition to any new or existing collection.  Will come with a Canagem specimen card.

This is a must have 96.3 gram Impact Breccia, also referred to as Suevite, from the famous Rochechouart impact structure in South Western France, near the village of Chassenon.  Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.

Named after the town of Rochechouart, the Rochechouart impact structure is located on the western margin of the French Massif Central near the city of Limoges, approximately 350 km (220 mi) south of Paris. Rochechouart (population about 3800) is built with rocks created or modified by the impact (impactites). Chassenon, a third of the size of Rochechouart, is also built of impactites. Impactite was used 2000 years ago for building Chassenon's monumental Roman baths of Cassinomagus.

The very fine materials (impactoclastites) are preserved forming a very fine layered horizontal deposits on top of the melt rich suevite (breccia with a debris matrix and both rock debris and melt fragments as clasts) near Chassenon.

The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc. This impactite was formed 186 million years ago.   This deformed rock fragments and partly molten are imbedded in a melt matrix showing typical flow structures from former melt.

This beautiful Impact melt rock comes from the 11 km-diameter highly eroded Dhala impact structure in India. The Dhala structure has an estimated age of about 2Ga (2,000 Ma), making it the third oldest terrestrial impact structure.

This is a rare and fantastic 8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 32x22x15 mm. 

Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites​. Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.
