Meteorites and Tektites


Canyon Diablo Meteorites

Meteorites are rocks from outer space. The iron type meteorites shown below are classified as IA, coarse octahedrites. For lots of great educational information about meteorites (that even I can understand!), visit The Meteorite Market which is owned by Eric Twelker and his family. Eric is an old friend of mine and has a wide variety of meteorites for sale. Of course we want to sell you a specimen, but if you happen to decide to purchase one elsewhere, do it at the Meteorite Market. To visit Eric's information page click here.
The origin of Canyon Diablo meteorites is the most famous impact crater in the world: Meteor Crater, Arizona. Located in northern Arizona near the city of Winslow, Meteor Crater is about 30,000 years old .
These iron meteorites are characterized by classic meteorite features like thumb-printing, sharp ridges, holes and bowls. Many contain inclusions of graphite. When a graphite inclusion pops out of the host meteorite it is called a graphite nodule. Another interesting fact about Canyon Diablo is the occurrences of carbonados or black diamonds formed by impact on earth or in space.
Each is a unique piece and the one in the photo you order is the one you will receive. We have included a ruler in the photo to provide a fairly accurate scale of the relative size of each specimen. If you have questions, please let us know via phone or e-mail.

Small Meteorites
(Canyon Diablo, Odessa and Sikhote-Alin)

We recently purchased some smaller Canyon Diablo, Odessa and Sikhote-Alin meteorites and are offering them to you at an attractive price. If you have been thinking about starting a collection, this is a great opportunity. These meteorites are fairly uniform in size and weigh about 4-5 grams each. We are offering them at $15.00 each - our choice. Be assured we will select a great specimen for you. An information card comes with each meteorite. These make great birthday or Christmas gifts for young collectors.

Canyon Diablo

See above for information about Canyon Diablo. Canyon Diablo and Odessa meteorites are very similar. They are both iron-nickel, Group I, coarse octahedrites. About the only difference in the appearance of the two is that the Canyon Diablos are a liitle more reddish in color than the Odessas.
Odessa

The Odessa crater was discovered in 1920. The crater and the meteorites found in it were first described in 1922 by Daniel Barringer. Ironically, Barringer, a mining engineer, was also the first to recognize and describe the Canyon Diablo crater and meteorites. It is approximately 500 feet in diameter, its rim rising about 6 feet above the surrounding plain. The crater is approximately 30 feet deep and filled with sand. Drilling attempts to locate any large, surviving meteorite in the main crater and four smaller craters nearby failed, leading to the conclusion that the main body of the meteorite had probably vaporized on impact.
The Odessa mineralogy is typical of iron meteorites. It consists primarily of Kamacite (90%). Taenite, Troilite, Graphite, Cohenite and Scheibersite are also found in Odessa meteorites.
Sikhote-Alin

The The Sikhote-Alin meteorite fell in the Maritime Territory, Federated SSR, USSR on February 12, 1947. The total known weight was over 23,000 kg. The fall of this iron meteorite produced 106 impact holes up to 28 meters in diameter over an area of 100m x 660m in the thick forest of the Sikhote-Alin Mountains. Many fragments weighing up to 300 kg in weight have been recovered.

Tektites

Tektites are small pieces of silica-rich (usually 65-80% SiO2) glass found in limited areas in a few regions on the Earth's surface. They are similar in composition and appearance to volcanic glass such as obsidian with colors generally ranging from black to green. Formed under somewhat mysterious conditions that preclude a volcanic (terrestrial) origin, F.E. Suess (who introduced the name tektite in 1900) considered them to be glassy meteorites. However, unlike other meteorite types, tektites have not been seen to fall from the sky.
Tektites are found in four major geographic areas and geological and radioactive dating indicates that different geographic groups of tektites have different ages: North American tektites, 33 million years; Czechoslovakian tektites, 15 million years; Ivory Coast (African) tektites, about 1 million years; Indochine tektites from Southeast Asia and Australia, 700,000 years or less.
In 1967 microscopic glass spheres similar in composition to tektites were discovered in deep-sea sediments in the Indian Ocean west of Australia and named microtektites. Similar microtektites have been found in deep-sea sediments off the Ivory Coast of Africa.
There are two current theories as to the origin of tektites. Both agree that the production of the molten silicate needed to form a tektite is the result of the impact of comets or large meteorites. Tektites are formed when a comet or meteorite collides with the earth - or moon - with such force that melted rock is "splattered" into the upper atmosphere. Here the droplets cool and harden into the shiny glassy shapes we call tektites.
Scientists differ about whether tektites were formed from impacts on the Earth or on the Moon! If tektites are extraterrestrial in origin, the moon is the only feasible source, since scientific information implies that tektites were involved in at least a brief extraterrestrial passage. Scientists involved in work on the origin of tektites have been fairly evenly split in their opinions about whether these fascinating rocks are terrestrial or lunar in origin.

The specimens offered below are indochinite tektites which are 70-80% SiO2. Indochinite tektites are the best known of the tektites coming from the Paulin District of Thailand. They are the classic teardrop and cigar shapes found in rice paddies throughout southeast Asia in Thailand, Laos and Vietnam. Tektites are generally found in strewn fields that are sometimes thousands of miles across.

We also have some Czechoslovakian Tektites which are the result of a meteor strike nearly 15 million years ago. This collision between a meteor and the Earth occurred in the Moldau River Valley in what is now the Czech Republic. These green gems are among the rarest minerals on earth. The color varies from a gray green to an emerald green. They can be carved with diamond cutting tools into various shapes and forms. Moldavites are claimed to have mystical qualities.
