Impactites

This is a great 34.2 gram Red Suevite Fallback Breccia from the Sääksjärvi crater in Finland. It has dimensions of 76x39x6 mm.  Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection item 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.

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.

Sääksjärvi is a lake in Kokemäki, Satakunta, western Finland, east of the town of Pori. The lake is notable because it overlies an impact crater.  The crater is 5 kilometres (3 mi) in diameter and is completely buried under the lake and is not visible at the surface. The age of the impact structure is estimated to be about 543 ± 12 Ma (million years ago), at the boundary between the Ediacaran and Cambrian periods. The enormous heat and pressure at the impact explosion created an interesting melt, a Suevite, and shattered rocks and dust which fell back into the crater area becoming cemented together over the centuries.  These rock formation is known as Fallback Breccia.

These are some of the best looking breccias we've found. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a rare and fantastic 26.8 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 51x40x25 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.

This is a must have 17.8 gram Impactite from Norrbo, Sweden.  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.

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 approx. 89 million years ago when a meteorite crashed into the earth.

This gorgeous slice displays very well.  It is amazingly light considering its mass of 42x38x9mm.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

Here we have for you an amazing 1.2 grams premium shaped Irghizite Tektite from the Zhamanshi Crater in Kazakhstan. Its Dimensions are 28x8x5 mm.  These specimen were first found in 2003 and date back 900,000 ± 100,000 years.

This stretched and twisted Irghizite is typical of this material. Unlike other Tektites which can be found hundreds of miles from their point of origin, this is found in and around the crater formed by the impacting body.  In this case it is speculated to be of cometary origin due to analysis of the elements contained within the Irghizites and other impactite found in the crater which are called Zhamanshinite.

This piece displays very well and is a very nice size showing multiple characteristics of its origin.  Would be a beautiful addition to any new or existing collection. Comes in a small specimen box and with a Canagem Collection specimen card.

Here we have for you an amazing 2.08 grams superbly shaped Irghizite Tektite from the Zhamanshi Crater in Kazakhstan. Its Dimensions are 23x10x7 mm.  These specimen were first found in 2003 and dates back 900,000 ± 100,000 years.

This is a must have 25.3 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 74x31x6 mm.  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.

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 beautiful Impact melt rock comes from the Stac Fada impact structure in Scotland. The structure has an estimated age of about 1.2Ga (1,200 Ma). The Stac Fada Member of the Precambrian Stoer Group in Scotland has previously been described as volcanic in origin. However, shocked quartz and biotite provide evidence for high-pressure shock metamorphism, while chromium isotope values and elevated abundances of platinum group metals and siderophile elements indicate addition of meteoritic material. Thus, the unit is reinterpreted as having an impact origin.

This gorgeous slice displays very well.  Would be a beautiful addition to any new or existing collection. Comes with two a Canagem Collection specimen card.

This is a must have 28.9 gram Impact Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in South Western France, near the village of Montoume.  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).

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 is a fantastic shatter cone from Montoume France weighing 19.6 grams and measuring 45x27x16 mm. Although not a meteorite, impactites and shatter cones are directly linked to them and their impacts.   Shatter cones are evidence that the rock has been subjected to an extreme shock with very brief high pressures.  This particular specimen from Montoume is classified as subvolcanic dike rock.

Shatter cones are rare geological features that are only known to form in the bedrock beneath large meteorite impact craters. They have a distinctively conical shape with thin grooves (striae) that radiate from the top (apex) of the cone. Shatter cones can range in length from 1 centimeter to several meters. The azimuths of the cones's axes typically radiate outwards from the point of impact, with the cones pointing towards the center of the impact crater.

This impactite was formed 186 million years ago.  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. Comes with a Canagem Collection specimen card.

This Henbury glass, or more specifically vesicular impactite, was found in the Northern Territory of Australia. Thirteen craters were found 8 miles southwest of the town of Henbury, the largest of which was 720 x 360 feet.  Henbury impactite was formed by a meteorite impact that occurred around 4,700 years ago. The meteorite is believed to have exploded upon entering the Earth's atmosphere, creating multiple craters which produced the impact glass.

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 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.
