Meteorite**Hassi el Biod 002, Pallasite Ung.**9.177 gram slice, Ultra Rare!!!

Description

Hello up for sale is Hassi El Biod 002, classified as the 10th Pallasite Ungrouped, Ultra Rare!!! This beautiful slice weighs 9.177 grams, has a nice polish and etch to 1 side, high quality, Saw cut surface shows angular cm-sized dark-orange olivine grains set in metal. There are also smaller scattered olivines set in the host metal. The modal abundances are approximately 60% metal, 38% olivine, 2% troilite.
Electron microprobe analysis and imaging reveal the presence of magnesian olivine, kamacite, and minor troilite. No other phases were detected with both EPMA and SEM searches. This slice will come with 2 COA cards, Streaming meteorites & Mark Lyon, comes with display case. Thanks for your interest and take care.

Hassi el Biod 002 (HeB 002)        28.6284, 4.7276
Ouargla, Algeria
Purchased: 2021
Classification: Pallasite (ungrouped)
History: Purchased in 2021 by Mark Lyon from a meteorite dealer in Mauritania.
Physical characteristics: Five identically appearing masses (total 10 kg) found together. Saw cut surface shows angular cm-sized dark-orange olivine grains set in metal. There are also smaller scattered olivines set in the host metal. The modal abundances are approximately 60% metal, 38% olivine, 2% troilite.
Petrography: (A. Ross and C. Agee, UNM) Electron microprobe analysis and imaging reveal the presence of magnesian olivine, kamacite, and minor troilite. No other phases were detected with both EPMA and SEM searches.
Geochemistry: (A. Ross, UNM) Olivine Fa7.7±0, Fe/Mn=24±1, n=6; metal Fe=95.4±0.4, Ni=5.2±0.1 wt%, n=5. Oxygen isotopes (K. Ziegler, UNM): 3 acid-washed fragments analyzed by laser fluorination gave δ18O= 2.820, 3.390, 3.386; δ17O= 0.338, 0.440, 0.650; Δ17O= -1.151, -1.350, -1.138 (linearized, all per mil, TFL slope=0.528).
Classification: Pallasite, ungrouped. This is a unique pallasite type both in terms of olivine composition and oxygen isotopes. Along with Milton, this meteorite is the only other ungrouped that is not a pyroxene pallasite, however Milton and this meteorite are not paired and do not have olivine compositions and oxygen isotopes that are similar.
Specimens: 25.7 g on deposit at UNM, Mark Lyon holds the main masses.

Steve Jurvetson says:
It is the result of the violent destruction of what would otherwise have been a planet during the formation of our solar system. It comes from the boundary between the silica rich mantle and the iron-nickel core of a now extinct planet, torn away by a catastrophic impact with another planet or asteroid. A mix of solid stone forming olivine crystals (37% by weight) in suspension in liquid metal (iron-nickel) was flung into space to cool over millions of years in a vacuum and zero gravity, forming this beautiful mixture (which could not be created on Earth).
