Besuchen Sie unsere Liste ausgewählter Marsmeteorite: Derzeit sind um die 35 Marsmeteorite bekannt. ( by chemical analysis confirmed to be pieces of the Red Planet Mars, which have been launched from the surface Mars by an asteroid impact.) The mean distance between the Earth and Mars is approximately of 78,300,000 km, that is, roughly half the distance from the Earth to the Sun. As compared to the Moon, which is some 380,000 km away, Mars is at appr. 200 times the distance. Among the 27000 meteorites known on earth to date, only 33 were torn off on the surface of Mars by violent impacts. These specimens are such the rarest matters on Earth. The rocks then orbited the sun and hit the Earth as meteorites. The SNC's (Shergottite, Nakhlite, Chassignite) have always been the most desired meteorites for collectors and are also some of the most valuable.

How do we know these Mars Meteorites are from Mars? |
Science is almost certain the SNC Group of meteorites derived from Mars because of their young ages, basaltic composition, and inclusion of gases with the same composition as the Mars atmosphere. Composition of gases of Mars meteorites are almost identical to those of samples tested on the Mars surface by the Viking probe. |

From which region on Mars did these meteorites come
from? The majority of shergottites seem to have a crystallization age of ~175 Ma, while others have ages of 330 to 575 Ma. The Shergottite group defines a big variety of scientifically interesting igneous samples from Mars. All are roughly built up by basaltic compositions and mineralogy but the isotopic compositions and trace elements cover a larger diversity. Element trend for shergottite melts and their source materials (Y. Ikeda and Shimoda) We classify the Shergottites according to their thermal history and mineralogy: Basaltic, Olivine-orthopyroxene-phyric and Olivine-Phyric-(olivine bearing porphyritic) group (You can view the 3 types of shergottite groups our sample list below ) There is also another system for the grouping of shergottites by: Textural study of basaltic Shergottites using crystal size distribution (Click) |

Unique type of Mars Shergottite: Almost pure Maskelynite (plagioclase glass ) - Dho-378
Galaxies most incredible meteorite recent
discovery!
One
fresh Mars Meteorite covered with almost 100% complete fresh black
fusion crust was discovered on June 17th 2000. It turned out to be one of the most interesting and unique meteorite discoveries ever. Dho 378 is only one of four Calcium poor Martian Meteorites in the world (beside ALH84001, Chassigny, and NWA 998) . Due to the presence of titanomagnetite the Dhofar 378 belongs to the rare titanomagnetite-bearing basaltic shergottite group. There is an extremely high possibilty that this glassy Martian rock will give us the possibility to get insight into intercrustal magmatic differentiation process on Mars and give hints for potential mining (Ti) missions on Mars. The high Fs content of the pyroxenes(Fs 40 to 93) and the high proportion of feldspar suggest that Dho 378 is a late Martian magmatic differentiate. Among basaltic shergottites Dho 378 represents the most evolved Martian magmatic liquid composition. Dho 378 experienced a 2 stage thermal history. A secondary melting at extremely high temperatures was followed by slow cooling (what the recrystallization of various plagioclas segments seem to confirm). Polished thin sections show that Dho 378 consists mainly of Maskelynite,, plagioclase glass, with minor minerals of hedenerbergite and ferroan clinopyroxenes (augite and pigeonite) pyrox-ferroite, fayalite, silica, titanomagnetite, ilmenite, sulfide, phosphate, and rhyolitic glass as the main minerals. Studies on Dhofar 378 undertaken by J. PARK and K. NAGAO, 1Laboratory for Earthquake Chemistry, Graduate School of Science, University of Tokyo, Hongo, Bunkyo-ku, Tokyo 113-0033, Japan proved that heavy fractionation occurred on Ne isotopic composition in Martian atmosphere. Neon is highly enriched in DHO 378 compared to those of other
shergottites.The trapped 20Ne is not enriched in the plagioclase glass NEW INSIGHTS ON MARTIAN ATMOSPHERIC NEON FROM MARTIAN METEORITE, DHOFAR 378: http://www.lpi.usra.edu/meetings/lpsc2006/pdf/1110.pdf) In terms of mineralogy Dhofar 378 is more similar to LA 001/002 than to other members of shergottite groups. CRYSTALLIZATION EXPERIMENT; IMPLICATIONS FOR THE CRYSTALLIZATION OF LOS ANGELES 001 AND DHO 378. Similar to Los Angeles the Cr is very low. Dho 378 is the first shergottite with a positive Eu anomaly. The amount of phosphates, mainly whitlockite, is only 1 % as deduced from the REE abundances. The host mineral of the REEs in all shergottites is whitlockite, which controls the bulk rock REE concentrations. Whitlockite has a negative Eu anomaly. But, in the case of Shergotty, Zagami, and Los Angeles the absolute Eu content of whitlockite is high enough to compensate the positive Eu anomaly of maskelynite. Only in Dhofar 378, with about 50 times more plagioclase glass than whitlockite, we observe a positive Eu anomaly. |

quality- very fresh! |
From which region on Mars did this meteorites come from? This basaltic shergottite belongs to the Olivine-orthopyroxene-phyric Group. The DAG 735 is the first ( found already 1997)and such the first and "original" Mars meteorite found in the Sahara!It is the most oriented of all known Mars Basalts found in the Sahara. It also is very fresh in appearance. Total mass was 588 g,Classification by: Frank Wlotzka, MPI and Matthias Kurz. Classification information: Porphyritic basalt with mm-sized olivines (normally zoned from Fa 28 to fa 37)in a finer grained matrix of pigeonites (Fs 25-28) and feldspar glass (An 65).A direct comparison with a PTS of DaG 476 shows that both Mars Meteorites are very similar and most probably paired.An exception is that this Mars Meteorite does not contain terrestrial carbonate veins, it appears less weathered than DaG 476/489/670.
This
meteorite is a Shergottite and is part of a group of meteorites called
the SNC's standing for Shergottites,
Nakhlites and Chassignites.

DaG 1037 - Marsmeteorit: das fehlende Shergottit Link vom Mars! Erhältlich nur bei uns!
DaG 1037 ist nicht nur einer der größten Mars Meteoriten der Welt, er ist auch deshalb so etwas besonderes, weil er das fehlende Shergottitglied vom Mars ist, denn er stammt aus genau jener Zone die vom Asteroiden getroffen wurde und daher weist dieser Stein extensive Schockspuren in Form von Adern, Impaktschmelzen und glasverwandeten Blasen (bis ca. 12mm) auf! Besonders der Olivin in DaG 1037 ist von einer unterschiedlichen Erscheinungsform und zeigt, dass er auf dem roten Planeten einem extrem starken Impakt Schock ausgesetzt war. Die zahlreichen Impakt Schockadern, Schmelzadern und Schmelztaschen legen die Vermutung nahe, dass dieses spezifische Gesteinsmaterial genau jener Bereich des Mars war, der von dem Asteroiden getroffen wurde, der die Ursache dafür war, dass das Material den Mars verlassen hat! Es ist sehr frisches Material! Glasige Textur, große Blasen bis zu 12mm mit Wänden aus schwarzem Silica Glas! Auch das Material sieht optisch etwas anders aus als DaG 476, 489 etc. (mehr glasige Textur, bis 12mm große Blasen mit Wänden aus schwarzem Silica Glas); Dieses Material ist dennoch sehr wahrscheinlich gepaart mit dieser Olivin-Phyrischen Shergottit Gruppe. Ausgedehntes Suchen nach diesem Material über eine lange Zeitperiode durch verschiedene Gruppen in späteren Jahren in diesem Gebiet (DaG 476, 489,735 .....DaG 1037)haben keinen weiteren Stein geliefert.
