(last update 15/12/13 Erich Haiderer)
Es gibt heute weniger als 50 verschiedene Meteorite, die einmal Teile des Mond unserer Erde (Mond-Meteoriten) waren
Das Gesamtgewicht aller nach extensivsten und aufwendigsten Suchen geborgenen Mond-Meteorite beträgt nur 38 kg (im Vergleich dau werden z.B: Tonnen an Diamanten in bester Schliefqualität jedes Jahr gefunden).
Aus diesen und anderen Gründen können die viele der Mondmeteorite als wirklich einzigartige und Schätze des erdnahen Weltraums betrahctet werden!
Wie gelangen Steine des Monds auf die Erde?

Wie können wir sicher sein, dass es sich tatsächlich um Mondmaterial handelt?
Mineralogische Zusammensetzung, chemische Analysien, isotopen-verhältnisse, Untersuchungen mit Mikrosonde, and textures of the lunar meteorites are all similar to those of samples collected on the lunar surface during Apollo missions.
Unlike meteorites originating from asteroids samples from the surface of earth's moon almost always contain free glass formed in space by impacts from space on the lunar surface.
Because of how the Moon formed, lunar highland material is composed predominantly of Anorthite which is a white, plagioclase feldspar that causes moons pale shimmering color.
Another plagioclase feldspar
Anortihisite is common on lunar highlands but
is quite uncommon on asteroids and on the surface of any other
planet or planetary satellites.

A completely new rare (prov. from a different unique lunar region) and interesting (extremely alkali-rich unlike any other lunaite) lunar type:
Lunar KREEP impact melt breccia
- Dho 1442
Find 2005; TkW: 120 g in total. Fusion crust absent.
Note: The mineralogy of this lunaite shows by far the highest Na2O value (appr. twice as high as
that of all other lunaites) as well as K2O content (K2O: 0.76) of all known Lunare meteorites. Most Lunaites have a K2O value of a seventh or less (of that of o 1442. Only Calcalong Creek and NWA 773 have a higher K2O value than the other Lunares but still only a third of that of Dho 1442Petrography: (Ivanova M.A., Lorenz C.A., and Nazarov M.A., Vernad.) Meteorite is a impact melt breccia containing lithic clasts, mineral fragments, glassy spherules, granulites and melt breccias embedded in a fine-grained melt matrix. It is a polymict breccia although the matrix/clasts ratio is varying from sample to sample of the meteorite. The lithic clasts population is presented by anorthosites, gabbroes, olivine gabbro-norites, gabbro-norites and norites. KREEPy and mare basalt clasts are present. The size of the clasts ranges from 0.02-8 mm; the main minerals are pyroxene and feldspar; minor - olivine, silica, chromite, ilmenite, Ca-phosphate, troilite and FeNi metal.
Geochemistry: (Ivanova M.A. and Kononkova N.N. (Vernad.) Chemical compositions of mineral phases are: feldspar An73-96Ab3.7-24.8; clinopyroxene En2.6-69.5Wo5.6-42.8 (Fe/Mn = 64 at.), orthopyroxene En60.8-77.1Wo1.2-4.1 (Fe/Mn = 69 at.), olivine Fo39.9-72.2 (Fe/Mn = 93 at.); ilmenite (MgO 5.5 wt%); FeNi metal (Ni 8.0 wt%; Co 0.6 wt%). Average glassy matrix composition (wt%): SiO2 49.6; TiO2 1.76; Al2O3 17.4; Cr2O3 0.20; FeO 10.7; MnO 0.15; MgO 7.16; CaO 11.1; Na2O 0.88; K2O 0.76; P2O5 0.84.
Classification: Achondrite (Lunare KREEP impact melt breccia with minor features of weathering.
Specimens: A total of 21.8 g of sample and two thin sections are on deposit at Vernad. An anonymous buyer holds the main mass of the meteorite.

DH0FAR 1443 - Anorthositic Breccia
DH0FAR 1443 18°25.00'N 54°25.50'E
Fund: 12 April 2001
Lunare (anorthositic breccia)
History: On April 12, 2001, one stone was found by an anonymous Funder in the DH0FAR region. Some years later three further tiny fragments were found within a few feet. The total mass of all stones is 36.7 g.
Physical characteristics: The rock is slightly weathered and relatively dark in hand specimen.
Petrography and mineralogy (A. Bischoff, IfP and E. H. Haiderer, Vienna): typical anorthositic breccia with light anorthositic clasts and abundant impact melt clasts embedded within a tough, partially molten matrix. This mostly devitrified matrix contains abundant vesicles and schlieren. Based on the optical appearance the rock has some similarities with DH0FAR 081 , however, the coordinates do not favor pairing.
Mineral compositions: feldspar ranges from An 83–98 with a mean of An 94.8 ± 3.5 ; pyroxene is Fs 12–49 ; mean: Fs 30 ± 9 ; and olivine is Fa 19–52 ; mean: Fa 35.5 ± 9 .
Classification: Lunare (anorthositic breccia).
Type specimens: 7.4 g and one polished thin section ( IfP , Mün); an anonymous collector holds the main mass.

1.Mond Meteorite - with troctolithe clasts from the original old Lunare crust and probably from the Northern region of the Far side of Mond:
4.5 Billion years ago: Earth struck by mars-sized object
4.4Billion years ago: Mond crust - radio date
This material dominates the northern
Lunare farside – an area called the Feldspathic Highlands Terrane.

Lunare anorthositic breccia: Dho 490
Very
rare, top quality Lunare meteorite (highly aesthetic), different in
appearance to other known Lunare meteorites! (It is not paired to any
other known Dhofar Lunaites)
Description and references
Beautiful material with surprising texture, very fresh:
$4 only for a gem box with appr.3mg of dust to grain sized Lunare material. (Note: due to these small sized grains the difference of Lunare dust to terrestrial dust is difficult to prove! Lunare and terrestrial grains of pyroxenes, olivine or feldspar virtually look identical). Only our Certificate of Authenticity and seal on the gem box proves that it is real Mond dust.
