Description: A unique meteorite known as Hassi Messauod 001 is being auctioned. This rare Nakhlite Martian was discovered in Ouargla, Algeria, on March 11, 2020, with a total known weight of 75 grams. The individual fragment on offer weighs 0.817 grams and boasts a striking dark black color with a glossy fresh fusion crust, well pronounced flow lines, characteristic of this rare type from a Martian volcano. It includes a display case and COA cards. Thank you for your interest, and be well!" Smithsonian says: Nakhlites, Martian meteorites named for Nakhla, are igneous rocks that are rich in augite and were formed from basaltic magma about 1.3 billion years ago. Their crystallization ages, compared to a crater-count chronology of different regions on Mars, suggest the Nakhlites formed on the large volcanic regions of Tharsis, Elysium or Syrtis Major Planum. It has been shown that the Nakhlites were suffused with liquid water around 620 million years ago and that they were ejected from Mars around 10.75 million years ago by an asteroid impact. They fell to Earth within the past 10,000 years. Basic information Name :Hassi Messauod 001 This is an OFFICIAL meteorite name. Abbreviation:There is no official abbreviation for this meteorite.

Later, I was acquired in 2021 by Matthew Stream from Aziz Zad. Physical characteristics: Specimen is grayish-brown and displays a slightly weathered, minor fusion crust. Petrography: (D. Sheikh,FSU) Specimen displays a cumulate texture (~1.1 mm grainsize) consisting primarily of compositionally zoned, prismatic or blocky (sometimes twinned) augite (displaying Fs-rich rims), ferroan olivine, and plagioclase; modal abundances: 75% augite, 15% plagioclase, 5% olivine. Accessory phases (modal abundance: 5%) are primarily found either in the mesostasis or within melt inclusions in augite or olivine grains; these phases include ferropigeonite, low-ca pyroxene, titanomagnetite, Si-Al-Na-Fe-K-rich glass, and fluorapatite. Geochemistry: Olivine (Fa73.31.0, range Fa72.6-74.5, Fe/Mn = 501, n=3), Augite (Fs30.14.7Wo38.41.4, range Fs22.8-37.9Wo34.9-40.3, Fe/Mn = 324, n=47), Pigeonite (Fs58.64.9Wo9.93.8, range Fs53.3-62.9Wo6.6-14.0, Fe/Mn = 312, n=5), Low-Ca Pyroxene (Fs64.54.1Wo3.10.9, range Fs61.1-70.2Wo3.0-5.3, Fe/Mn = 352, n=8), Plagioclase (An37.21.3Or2.90.5, range An35.3-39.4Or2.0-4.0, n=27). Classification: Martian (nakhlite). Sample is a martian meteorite due to the Fe/Mn ratios of olivine and pyroxene and due to the plagioclase composition. Sample is a nakhlite due to the high modal abundance of augite and cumulate texture observed. Specimens: 15.2 g atUCLA, main mass with Matthew Stream.
