Impactites

This is a great 85.2 gram Impact Melt Breccia from the Sääksjärvi crater in Finland. It is amazingly light considering its mass of 95x51x15 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. There are impactite rocks in the southwestern region from the crater confirming its extraterrestrial origin. At the time of its discovery, only one impact crater (Lappajärvi) was known in Finland.  

Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is a rare and fantastic 5 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 25x14x13 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 an outstanding Impact Melt Glass specimen or bomb weighing 1.8 grams.  Its dimensions are 18x17x13 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.

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. 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 17 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 65x38x4 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.

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 15.4 gram Impactite, monomict impact breccia from the Agoudal, Imilchil impact structure, Morocco.  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. According to the state of conservation of the meteorite into the sedimentary layers "Soltanian" and the dating of ancient lake sediments of the Isli lake, we can estimate their age limit to 40,000 years. 

More than 183 structures of meteoritical impacts are highlighted on the Earth, including only three reported dual impact craters. The impact craters of Isli and Tislit are respectively located at 10 km and 4 km from the Imilchil village on the Central High Atlas in Morocco at respective altitudes of 2272 and 2266 meters. They are spaced apart from each other by 9.4 km. The origin and the date of formation of these two lakes are still unknown today. Surveys undertaken near them and in the surrounding areas leads to believe that they correspond to a dual meteoritical impact crater.

Polymict and monomict breccias were observed at the edges of these craters but they don’t form big masses because of erosion. They consist of irregular fragments with millimeter and centimeter sizes, in a carbonate matrix. In the breccias collected on the southern edges of the Isli crater, we noted the presence of several shocked quartz grains in planar structures associated with rolling extinction, indicators of shock metamorphism. 

This gorgeous specimen displays very well with a mass of 38x31x21 mm. Would be a beautiful addition to any new or existing 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.

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.
