List Of Meteorites On Mars
Martian rocks and outcrops have been studied ''in-situ'' by various landers and rovers. While many of the rocks identified on the Martian surface are similar to each other, some have been considered scientifically important or otherwise notable and have been subjected to more extensive study or public interest. Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than are not to be given official names. Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion among researchers. Often rocks are named after the children or family members of astronauts or NASA employees. The rocks at the landing site of the ''Sojourner'' rover were given names of cartoon characters. Among them were P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Martian Meteorites
This is an incomplete list of Martian meteorites i.e. meteorites that have been identified as having originated from Mars. , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. On 17 October 2013, NASA reported, based on analysis of argon in the Martian atmosphere by the Mars ''Curiosity'' rover, that certain meteorites found on Earth previously only thought to be from Mars, could now be confirmed as from Mars. The list does ''not'' include meteorites found on Mars by the various rovers.

Heat Shield Rock
Heat Shield Rock is a basketball-sized iron-nickel meteorite found on the Meridiani Planum plain of Mars by the Mars rover ''Opportunity'' in January 2005. Informally referred to as "Heat Shield Rock" by the Opportunity research team, the meteorite was formally named Meridiani Planum meteorite by the Meteoritical Society in October 2005 (meteorites are always named after the place where they were found). Discovery ''Opportunity'' encountered the meteorite entirely by chance, in the vicinity of its own discarded heat shield (hence the name). ''Opportunity'' had been sent to examine the heat shield after exiting the crater Endurance. This was the first meteorite found on another planet and the third found on another Solar System bodytwo others, the millimeter-sized Bench Crater and Hadley Rille meteorites, were found on the Moon. Analysis The rock was initially identified as unusual in that it showed, from the analysis with the Mini-TES spectrometer, an infrared spectrum th ...

Hadley–Apennine (Moon)
Hadley–Apennine is a region on the near side of Earth's Moon that served as the landing site for the American Apollo 15 mission, the fourth crewed landing on the Moon and the first of the " J-missions", in July 1971. The site is located on the eastern edge of Mare Imbrium on a lava plain known as Palus Putredinis. Hadley–Apennine is bordered by the Montes Apenninus (often referred to as "Apennine Front"), a mountain range, and Hadley Rille, a meandering channel, on the east and west, respectively. Data obtained from the composition of soil samples collected on Apollo 15 show that most (about 90%) of the samples from the Apennine Front are brown-glass breccias, and approximately 60–70% obtained from the mare surface are basalt. Although the basalts seem to vary in their texture, their ages appear to be approximately the same. Most of the samples obtained on the Apennine Front are KREEP (potassium, rare-earth elements, phosphorus) materials, anorthosites, Recrystallization ...

Big Bertha (lunar Sample)
Lunar Sample 14321, better known as "Big Bertha", is a lunar sample collected on the 1971 Apollo 14 mission. It was found in the Fra Mauro (crater), Fra Mauro region of the Moon. At , this breccia rock is the third largest Moon sample returned during the Apollo program, behind Big Muley and Great Scott (lunar sample), Great Scott. Big Bertha contains an embedded fragment of granite-like rock which may have been ejected from the Earth by a meteorite impact billions of years ago. If this origin were to be confirmed, that fragment would be the oldest dated rocks, oldest known Earth rock. This claim has been disputed, however.Paul H. Warren, Alan E. Rubin (2020): "Trace element and textural evidence favoring lunar, not terrestrial, origin of the mini-granite in Apollo sample 14321". ''Icarus'', volume 347, article 113771.

Enstatite Chondrite
Enstatite chondrites (E-type chondrites) are a rare form of meteorite, rich in the mineral enstatite. Only about 200 E-Type chondrites are currently known, comprising about 2% of the chondrites that fall on Earth.Norton, O.R. and Chitwood, L.A. Field Guide to Meteors and Meteorites, Springer-Verlag, London 2008 There are two main subtypes: EH and EL, classified based on their iron content. Origin E-type chondrites are among the most chemically redox, reduced rocks known, with most of their iron taking the form of metal or sulfide rather than an oxide. They tend to be high in the mineral enstatite (MgSiO3), from which they derive their name. Based on spectral analysis, it has been suggested that the asteroid 16 Psyche may be the common parent for this type of meteorite. Composition Unlike most other chondrites, the minerals in enstatite chondrites contain almost no iron oxide; they are the most oxygen-poor silicate rocks known. They were supposed to be the driest objects in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daubréelite
Daubréelite is a rare sulfide mineral. It crystallizes with Cubic crystal system, cubic symmetry and has chemical composition of Fe2+Cr3+2S4. It usually occurs as black platy aggregates. Naming and history Daubréelite was named after the French mineralogist, petrologist and meteoriticist Gabriel Auguste Daubrée. The mineral was first described in 1876 in the ''American Journal of Science''. Its type locality is the Coahuila meteorite, Bolsom de Mapimí, Coahuila, Mexico. Classification In the Nickel-Strunz classification daubréelite is part of the "Sulfides and Sulfosalts" and further a "metal sulfide with a metal-sulfide ratio of 3:4 and 2:3". Occurrences Daubréelite is found in iron meteorites as an inclusion in meteoric iron (kamacite and taenite). Further paragenesis, paragenetic minerals are alabandine, enstatite, graphite, plagioclase and schreibersite. According to one source daubréelite has been described from 34 localities.

Albite
Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. It represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula . It is a tectosilicate. Its color is usually pure white, hence its name from Latin, . It is a common constituent in felsic rocks. Properties Albite crystallizes with triclinic pinacoidal forms. Its specific gravity is about 2.62 and it has a Mohs hardness of 6 to 6.5. Albite almost always exhibits crystal twinning often as minute parallel striations on the crystal face. Albite often occurs as fine parallel segregations alternating with pink microcline in perthite as a result of exolution on cooling. There are two variants of albite, which are referred to as 'low albite' and 'high albite'; the latter is also known as 'analbite'. Although both variants are triclinic, they differ in the volume of their unit cell, which is slightly larger for the 'high' ...
