Impactites

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.

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 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 is a rare and fantastic 54.4 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 68x33x22 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 80.5 gram Impact Melt Rock from the Dellen Crater, north of Stokholm, Sweden. Some locals call these rocks by the name of “dellenites”, although officially they are impact melt rocks.  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 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.  Dellen impactites were divided into three impactite groups: (i) suevitic impact breccias with lithic and melt clasts, (ii) impact melt rocks, and (iii) shocked (parautochthonous) target rock. In turn, impact melt rocks were divided into (i) clast-rich, (ii) clast-poor, and (iii) clast-free types.  The Dellenite type material was classified as clast poor impact melt breccia.

This gorgeous slice displays very well.  It is amazingly light considering its mass of 87x73x6   mm.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
