These meteorites are real meteorites that may have been proven to be another Work in progress. A solid natural object reaching a planet’s surface from interplanetary space. Solid portion of a meteoroid that survives its fall to Earth, or some other body. Meteorites are classified as stony meteorites, iron meteorites, and stony-iron meteorites. These groups are further divided according to their mineralogy and Click on Term to Read More, have questionable past and/or Meteorite not seen to fall, but recovered at some later date. For example, many finds from Antarctica fell 10,000 to 700,000 years ago. Click on Term to Read More circumstances, or have not found scientific consensus regarding their meteoritic origin.
In alphabetical order:
- Al Haggounia 001 – Listed and still often sold as an Aubrites are named for the Aubres meteorite that fell in 1836 near Nyons, France. They are an evolved achondrite that is Ca-poor and composed mainly of enstatite (En100) and diopside (En50Wo50) with minor amounts of olivine (Fa0) and traces of plagioclase (An2-8). They contain large white crystals of enstatite as Click on Term to Read More, but due existence of many Roughly spherical aggregate of coarse crystals formed from the rapid cooling and solidification of a melt at ~1400 ° C. Large numbers of chondrules are found in all chondrites except for the CI group of carbonaceous chondrites. Chondrules are typically 0.5-2 mm in diameter and are usually composed of olivine Click on Term to Read More was reclassified by Dr. Alan Rubin as a “Vesicles appear in nature when they are produced within lava (extrusive aphanitic igneous rock) whose dissolved gases come out of solution (are released) due to the drop in pressure during an eruption. The resulting lava solidifies around the gas bubbles capturing their shape inside and outside the rock. Vesicles do Click on Term to Read More, incompletely melted, EL Chondrite meteorites are the most common accounting for 83.6% of falls. Chondrites are comprised mostly of Fe- and Mg-bearing silicate minerals (found in both chondrules and fine grained matrix), free Fe/Ni metal (found in various states like large blebs, small grains and/or even chondrule rims), and various refractory inclusions (such Click on Term to Read More impact melt rock”. Also, this meteorite is extensively weathered.
- Baygorrya – Classified as an independent find from Uruguay, this meteorite was found to be Campo del Cielo. Due to Argentina’s strict rules, it appears that the scammers smuggled out a Campo del Cielo meteorite and claimed to have found it just over the border in Uruguay in a grass field near the Baygorria dam.
- Datil – This supposed find by Michael Cottingham has never been published in the Meteoritical Bulletin and never will do to its highly suspect history.
- Hambleton – This One of two main classes of stony-iron meteorite, the other being mesosiderites. Pallasites are igneous in nature and characterized by crystals of olivine, sometimes peridot (green gem quality clear olivine crystals), embedded in a matrix of Fe-Ni metal. The type specimen, weighing 680 kg, was found in the mountains near Click on Term to Read More was found in Thirsk, North Yorkshire, beside a forest track by meteorite dealer and hunter, Rob Elliot, in 2005. There is no proof of mischief, but some in the meteorite community at large find the circumstances to be suspect.
- Lovina – This meteorite is classified in the Meteoritical Bulletin as an Iron, Ataxite. However, buyers should be aware that there is a great deal of controversy among museum curators and meteoriticists as to whether it is even a meteorite. The anomalous structure of Lovina is thought by some to be the byproduct of metal smelting furnace. In the follow-up paper titled, “LOVINA: IS THIS A METEORITE?” by K. Nishiizumi and M. W. Caffee, they stated that “based oncosmogenic Radioactive isotope - Atomic nuclide that decays radioactively . Click on Term to Read More concentrations, it is our opinion that
Lovina is unlikely to be of extraterrestrial origin.”
- Mercantour – The trace elements measurements conducted by M. D’Orazio at University of Pisa reveal significant Ba and Sr enrichment, a signature similar to meteorites found in hot deserts. This meteorite is now called Nova 054.
- Shirokovsky – At the time of its introduction, many collectors, dealers and some institutions were fooled into buying this “new” pallasite. Labeled now as a pseudo-meteorite in the Meteoritical Bulletin, it is now considered by collectors as a collectible “meteor-wrong” and ironically sells for more per gram than real pallasite meteorites.
