Impactites

This is a must have 155.6 gram Impact Melt Rock from the Dellen Crater, north of Stokholm, 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 making a round crater which is now a lake about 11 miles wide. The term tagamite was introduced in 1975 to describe impact rock from the Popigai crater in Russia. Varieties of tagamites are described based on crystallinity, texture and clast content.   HT Tagamite differs from other material due to the complete melting of the crystalline matrix and then being subjected to rapid cooling. 

This gorgeous slice displays very well.  It is amazingly light considering its mass of 83x51x27 mm.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a must have 52 gram Impact Breccia also referred to as Suevite coming 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.

Indochinite is a variety of the mineral tektite, which is a natural glass formed by the intense heat and pressure of a meteorite impact.  These tektites are usually found as small, aerodynamically shaped objects, often teardrop or irregular in shape, resulting from the molten material solidifying as it cooled rapidly after being ejected from the impact site.

Indochinites are believed to have formed around 780,000 to 800,000 years ago, following a significant meteorite impact event that likely created the Southeast Asian tektite strewn field.  The strewn field is quite large, and the tektites can be found scattered over a vast area which includes Vietnam, Laos, and Thailand.   

This piece displays very well, showing multiple characteristics of its origin.  The specimen has a weigh of 51 grams and dimensions of 45x32x23.  Comes with a Canagem Collection specimen card.

This is a rare and fantastic 78.3 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 54x48x31 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 620 gram impact melt rock from the Gallejaur Crater, northern 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.

Rocks, interpreted as impact generated lithologies, occur in a large area surrounding the Gallejaur magnetic structure at latitude 65°10/longitude 19°30 in northernmost Västerbotten County in northern Sweden. These rocks comprise a variety of different types of breccias: authigenic The Gallejaur structure is located in the central part of the Skellefte mining district in the Precambrian Baltic Shield. The ca. 1.9 Ga old Skellefte district is an extensively mineralized, mainly felsic, submarine volcanic belt.  The rocks are described as impact-generated, have been called the Vargfors Group and overlie the Skellefte volcanics and sediments with an angular unconformity.  The youngest rocks in the area, intruding the Skellefte district supracrustals and probably the impact-generated rock, are A/I-type granitoids belonging to the Revsund-Adak granite suite, which have been dated at ca. 1.80 to 1.78 Ga.

This is a great 145.8 gram Red Suevite Fallback Breccia from the Sääksjärvi crater in Finland.

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 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.

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.
