Impactites

This is a must have 17.4 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 39x28x20 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

This is an outstanding Impact Melt Glass specimen or bomb weighing 4.51 grams.  Its dimensions are 27x16x14 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. 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.

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 fantastic shatter cone from France weighing 7.8 grams and measuring 29x23x15 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.

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 is a great 24.3 gram Impact Melt Breccia from the Gardnos Crater in Norway.  It is amazingly light considering its mass of 67x44x4 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.

This impactite was formed between 385 and 900 million years ago in Precambrian time when a meteorite crashed into the earth making a ~5 kilometers wide crater locally known as the Hallingdal Impact Crater.

This is a fantastic Impactite Fallback Breccia from Germany weighing 22.9 grams and measuring 60x37x6mm. Although not a meteorite, impactites and shatter cones are directly linked to them and their impacts. The Steinheim Basin today exhibits a distinct morphological depression that is ∼110 m deep and ∼3.5 km in diameter; the height of the central uplift totals to more than 140 m. The original size of the pristine crater is estimated to be ∼3.8 km with an original depth of ∼205 m.

As this drainless morphological depression was filled by lake sediments shortly after the impact, the primary crater morphology is widely preserved. The crater rim is formed by steeply inclined and intensely brecciated Upper Jurassic limestone blocks that also contain numerous shattered chert nodules, as well as some loose blocks of the host limestone. An impact breccia, referred to as the so-called ”Primäre Beckenbrekzie” (“primary basin breccia”) and interpreted as a “fallback breccia”, is known from many drillings in the Steinheim Basin.

Mainly composed of Middle to Upper Jurassic limestones, marls, mudstones, and sandstones, the impact breccia inside the morphological depression of the Steinheim Basin is overlain by lake sediments and is obviously preserved in its original thickness and position.   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.

This is a must have 27.4 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 67x37x5 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.
