Tektite Locations - courtesy University of Texas
Scientists theorize that tektites are formed by rapid heating and subsequent cooling of quartz-rich soils and rocks - large meteorite impacts provide enough energy to melt and disperse soils and rocks - forming tektites

Chinese Tektite - 46.28 grams
Our sample is from the the Australasian strewn field - the largest of all of the strewnfields - covering an estimated 10% of the Earth’s surface

Chinese Tektite - 31.24
The round shape is formed if heated material ejected from the impact was rotating on all three axes keeping the force distributed evenly

Dakhla Glass Locations
Dakhla Glass was discovered by Maxine Kleindienst in 1987 at the Dakhla (Dakhleh) Oasis in Egypt - it has been found in four different locations

Dakhla Glass - 10.77 grams
A chemical analysis showed that the glass was created in temperatures so high that the meterial could only have been the result of an impact event - the samples also contain strands of molten quartz - a signature of meteorite impacts

Dakhla Glass - 10.77 grams
Our amazing specimen also contains lechatelierite which is also restricted to only being contained in impact melt-bearing materials

Flinders Ranges and Lake Torrens
Edeowie Glass is only found between Flinders Ranges (in the middle) and the dry salt Lake Torrens (to the west) in Australia - Edeowie Glass is believed to have been created by an impact event

Edeowie Glass - 21.55 grams
Our specimen is a slag-like, opaque glass found as a vesicular material or in thin masses in an area about 55 kilometers long and 10 kilometers wide along the western side of the Flinders Ranges

Edeowie Glass - 21.55 grams
The specimen displays shock metamorphism in the quartz which points to the thermal source as being an impact

Lunar breccia
This NASA moon rock is typical of most of the Apollo samples which were breccias - this really demonstrates how pervasive impacts have been throughout lunar history

Château de Rochechouart
This French Château is built from carved blocks of breccia generated during a meteorite impact - a number of different types of impact breccia are visible as different colors in the church facade

German Impact Breccia
Our specimen is a composite rock made by the solidification of a mix of irregularly sized and shaped heated rock pieces - it was formed by an impact event which first shattered and then welded the compacted pieces together

Henbury Impactite
The twelve Henbury craters are located in a protected area in the Northern Territory of Australia 145 kilometres southwest of Alice Springs - image courtesy Michael Farmer

Henbury Impactite - 2.81 grams
The craters range from 7 to 180 metres in diameter and up to 15 metres in depth - they were formed when the Henbury meteor broke up before impact

Henbury Impactite - 2.81 grams
Our impactite sample is an earth rock modified by the impact of a the meteorite - it is comprised of shock-metamorphosed material and melts - suevite

Tektite Formation
If heated material ejected from the impact was rotating and the centrifugal force was on two axes - it created an oval shape or with more speed it stretched into a dumbbell shape or even split into two tear-drops - courtesy tektites.co.uk

Indochinite - 44.04 grams
This collection piece is a good example of the dumbbell shape which results from the pulling effect of rotation on the heated material while it fell back to Earth
