Impactites

This is a 418 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 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 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.

This is a 40.7 gram Impact Melt Rock from the Dhala Impact Structure, India. It measures 53x51x9 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 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 must have 222.8 gram Metal Ore Copper rich Impact Breccia from the famous Sudbury Astrobleme Impact Structure in Ontario Canada. Its dimensions are 110x70x10 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 pieces you'll ever own. 

About 1.87 billion years ago, an object from space nine kilometers in diameter slammed into Canada, a little north of Sudbury, Ontario creating the second largest impact structure on the earth. This impact was equivalent to a billion tons of TNT. An impact so big it cracked the earth, and in fact there are still earthquakes because of that event today!  The many mineral rich deposits and strange rock formations in such close proximity has attracted attention for 100's of years, long before its impact origin was known. 

Note that this is not a meteorite but a slice of Earth rock, altered by the impact of a very large meteorite.  This came from the ring of the impact and is the harder to find gold-copper-bronze colored impactite described as a metal-rich breccia and sulfides composed chiefly of some amount of iridium, cobalt & selenium. In addition, most of these specimens will contain nickel, iron, sperrylite and pentlandite as well as minor amounts of other metals, metallic & silicate minerals."

The Azuara polymict impact breccia refers to the impact material from the 38 million year old twin (multiple) impact structures Azuara / Rubielos de la Cerida in Northern Spain.

This polymict impact breccia was found in the area of Santa Cruz de Nogueras near the center area of this large multiple impact structure.  This is partly melted and/or decarbonized limestone fragments in a dense and extremely hard matrix showing flow texture.  The breccia is considered an equivalent to suevite impactites in other impact structures. This beautiful slice has dimensions of 110x51x11 mm and weighs 122 grams.
