View a
list of fine mars meteorites (火星的陨星,火星の隕石):
There are now 29
meteorites known by chemical analysis 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.

Note: Most of the prices will again
increase May 30th 2009 by at least 10%:This is caused on one hand because of big demand and
limited stock in our extraterrestrail material - on the other hand due
the exchange rate is
getting more and more
a bit of a challenge-
some of you might have an idea of the reasons- ,
which seem to be surprisingly

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.

Alternate
Grouping System Shergottites |
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

Unique type of
Mars Shergottite: Almost pure
Maskelynite (plagioclase
glass )
- Dho-378
incredible meteorite discovery!
One fresh Mars Meteorite
cove red 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 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
phase but in pyroxene-rich phase of this meteorite (J. PARK and K. NAGAO,2006

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.
Special thanks to Prof. Hiroshi Takeda, Chyba Univ., Japan et al for
recognizing Dhofar 378 as true meteorite and proving its origin
to
be from Mars. Note it was previously analyzed by otherwise excellent
scientists by mistake as terrestrial lava Xenolithe (I will call no
names!), as the material looks indeed intriguing.

Shergottite - NWA
856
A single
meteorite of 320 g was found in Morocco in March 2001. The exact
location of find is unknown.
It is a basaltic shergottite - the texture is similar in appearance
as Shergotty & Zagami.
The meteorite
is a fine-grained basaltic lithology consisting mainly of
pyroxene (70 vol%) and maskelynite (23
vol%). Accessory minerals include merrillite, apatite, pyrrhotite,
chromite, Fe-Ti oxides, silica (stishovite) and baddeleyite.
Melt
pockets with phenocrysts and submicron-sized needles of stishovite
are present.

From
which region on Mars did this meteorites come from?
DaG735
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. This gemmy
Mars Meteorite consists primarily of olivine, chromite, pigeonite
, augite, orthopyroxene. It contains magmatic inclusions within the
olivine.
These consist dominantly of pyroxenes and feldspathic
glass.
The olivines have the range Fo
60-62 (phenocrystic olivine
ranges from Fo
78
to Fo
59 (Ikeda).
Magmatic inclusions
Yukio Ikeda: Unusual inclusions occur within
olivine megacrysts in the DaG735 olivine-phyric shergottite. They
consist of pyroxene and chromite in a ratio of about 2:1, and show
strange textures.
They are grouped into two types, symplectic and
non-symplectic.
The pyroxenes in unusual inclusions are similar in
composition to those in the main lithology of DaG735, but the
chromites differ in TiO_2 contents
which are lower by half than
those of chromites in the main lithology.
The symplectic textures
indicate exsolution origin of the unusual inclusions within olivine
megacrysts, and the reaction to produce the unusual inclusions
suggests
that the original olivine megacrysts may have contained
some amounts of Cr^(+2) in addition to Cr^(+3), and the Cr^(+2) was
oxidized
to Cr^(+3) during the formation of the unusual inclusions.
Whole Abstract from Y.Ikeda
The Mars Rover Spirit found in
2004 on one of its exploration raids on the Red Planets surface in several
rocks (called Mazatzal, Humphrey and Adirondack) material
composed
of olivine, pigeonite and plagioclase in a way that looks almost identical
to DaG 735
Studies of the thermal history
of this rock (e.g. rapid cooling rate of the melt) suggests that this
material originates from an extruded
lava flow near the Marss surface.

DaG 1037 - Martian Meteorite:
Shergottite
DaG 1037 is not only one of world's biggest mars meteorites it is also special because it is the missing Shergottite link from Mars!
Opx is occuring as cores in prismatic pyroxene
phenocrysts!
The
olivine is of different appearance in DaG 1037 and reveals that it was extremely heavy exposed to a major impact shock event on the Red Planet.
The numerous impact shock
veins, Melt veins + melt pockets suggest that this specific rock material was exact the zone on Mars that was hit by the asteroid that caused the material to leave Mars! It is very fresh material!
Nine stones of aTkW of
4010g were found early 1999 in the sand desert of DaG, within a few feet.
The biggest individual was a complete individual of 3090g, with perfect
orientation and fresh appearance.
The
name Shergottite describes interesting meteorite material that originated from
Mars .Mars meteorites have been launched from the surface of Mars by an
asteroid impact.
The SNC's have always been the
most desired meteorites for collectors and also some of the most valuable. This
gemmy stone consists primarily of olivine, chromite, pigeonite , augite,
orthopyroxene.
This basaltic shergottite
belongs to the Olivine-orthopyroxene-phyric Group:
The Mars Rover Spirit found in
2004 on one of its exploration raids on the Red Planets surface in several
rocks (called Mazatzal, Humphrey and Adirondack) material composed
of olivine, pigeonite and plagioclase in a way that looks almost identical
to DaG 876
Studies of the thermal history
of this rock (e.g. rapid cooling rate of the melt) suggests that this
material originates from an extruded
lava flow near the Marss surface.
Although this material looks optically different than the DaG 476, 489,
etc. (more glassy texture, large vesicles of up to 12mm with walls of
black silica glass) this material is very likely paired with this olivine-phyric
shergottites group.
Extensive searches over a long period of time by different groups in later
years for this material in this area (DaG 476, 489,DaG735.... DaG 1037)
didn't yield any further stone.
