"Meteorites" is a great introduction to the entire science surrounding these enigmatic little rocks from space. It is written at an accessible level that would be ideal as a reference for high school students or for someone just developing an interest in the field of meteorites/5(17).
Meteorites are the last stage in the existence of these type of space rocks. Before they were meteorites, the rocks were meteors. Before they were meteors, they were meteoroids. Meteoroids are lumps of rock or metal that orbit the oids become meteors when they crash into Earth’s atmosphere and the gases surrounding them briefly light up as “shooting stars.”.

In general, meteorites are heavier than Earth rocks of the same size because they have a higher nickel-iron content.
Naturally-occurring Earth rocks are usually poor in metals, particularly nickel, in comparison to meteorites. The softball-sized iron meteorite (Losttown) on the left weighs over pounds, while the large, regmaglypted iron on. Stone Meteorites. The largest group of meteorites is the stones, and they once formed part of the outer crust of a planet or asteroid.
Many stone meteorites-particularly those that have been on the surface of our planet for an extended period of time-frequently look much like terrestrial rocks, and it can take a skilled eye to spot them when meteorite hunting in the field. Below are the approximate properties of four different typical asteroids which probably exist, based on four meteorites.
(Chemical analysis in weight percent. Extracted from NASA SP, except for the iron meteorite.) Minerological, chemical and physical properties of four different asteroids based on four different meteorites.
Chemical Composition of Meteorites. Magnesium & Iron. MgO, Fe 2 O 3 (T), & MgO / Fe 2 O 3 (T) vs. Fe 2 O 3 (T) + MgO. MgO. Among meteorites, MgO necessarily increases with Fe 2 O 3 (T) + MgO.
Some terrestrial rocks lie off the trend because they have MgO/Fe 2 O 3 (T) ratios outside the range for meteorites (below). High-MgO terrestrial rocks are mainly ultramafic. A meteorite classification system attempts to group similar meteorites and allows scientists to communicate with a standardized terminology when discussing them.
Meteorites are classified according to a variety of characteristics, especially mineralogical, petrological, chemical, and isotopic properties. Meteorites range in age. The oldest particles in a meteorite, calcium-aluminum-rich inclusions from carbonaceous chondrites, have been dated at years old Meteorites that originate from asteroids are all ~ billion years old.
Meteorites that originate from the Moon range in age from to billion years old. The Handbook of Iron Meteorites was originally published by the University of California Press in for the Center for Meteorite Studies at Arizona State University. It has been digitized at the University of Hawai‘i as it is still an extraordinarily valuable resource and is no longer in print.
Put in the simplest of terms, meteorites are rocks. Like ter-restrial rocks the majority of meteorites are made of aggre-gates of crystalline minerals. For the most part the minerals of meteorites are common to terrestrial rocks but the way in which they are displayed in meteorites is unique to Size: KB.
Meteorites, by Alain Carion. This is a really great book, full of photos and tons of information about many meteorites, their origins, various falls. I met Alain a few years ago at the Tucson Gem Show and marveled at his collection and items he had for sale.

Building Blocks of DNA Found in Meteorites from Space. By Charles Q. Choi 08 August Shares. a very rare type of meteorite with a different chemical composition.
This was. However, some meteorites may contain elements and minerals that are not common on this planet. For example, scientists found oldhamite in a meteorite they recovered in California. Oldhamite is a calcium sulfide that you rarely find on Earth.
Inhundreds of meteorites fell over Colorado, Nebraska and Kansas. Put these in chronological order from oldest to youngest: Chondrules, Martial Basalt, Chondrites, CAI's. CAI's, chondrules, chondrites, Martial basalt. Name the pattern which forms in iron meteorites because of the segregation (or exsolution) of Ni-rich and Ni-poor alloys.
The bencubbinites are strange meteorites that contain more than 50% nickel-iron. If you consider this, they could be easily regarded as true stony-irons, but their mineralogical and chemical properties clearly put them into the clan of the carbonaceous chondrites, or more strictly speaking into the CR clan.
Right: The chemical structure of glucose and other naturally occurring sugars. Glucose is the primary "fuel" molecule used for generating energy in cellular respiration. Sugars like these are larger than the ones Cooper et al found in the Murchison and Murray meteorites.
There is, however, preliminary evidence that these larger sugars might be. Buy meteorites Meteorite books Contact me More These are some great books to get you started. Field Guide to Meteors and Meteorites Is a great book for collectors that are just starting out and gives a nice overview of everything about collecting and searching for meteorites.
It also goes in depth in a lot of topics and offers simple ways to. significantly more abundant in meteorites, was found in unusually high amounts in the sedimentary rock of the K-T boundary.

Meteorite Chemicals May Have Started Life on Earth--and Space Take one simple compound, add powdered meteorite and the solar wind, and you get building blocks of life By Anthony King, Chemistry Author: Chemistry World.
the composition of meteorites is virtually identical to asteroids. This means that ostensibly there are only 2 possible options: either asteroids are made up of meteorites just smashed together, or meteorites are just pieces of asteroids broken off.
It turns out that both of those options are true.
