Impactites

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 27.8 grams and dimensions of 33x32x21.  Comes with a Canagem Collection specimen card.

This is a fantastic shatter cone from France weighing 17.4 grams and measuring 38x26x16  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 fantastic Impactite Fallback Breccia from Germany weighing 67.3 grams and measuring 75x59x10mm. 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 great 19.5 gram Impact Melt Breccia from the Gardnos Crater in Norway.  It is amazingly light considering its mass of 60x51x3 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. 

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

This is a must have 24.4 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 41x31x27 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.

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.
