Northwest Africa 14425 (NWA 14425)

(Northwest Africa)

Purchased: 2021 Feb

Classification: Enstatite chondrite (EH3)

History: Purchased by Jason Whitcomb in February 2021 from an Algerian dealer.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) Mostly relatively small enstatite-forsterite-bearing chondrules (exhibiting a wide size variation, apparent diameter 380±410 µm, N = 24) are set in a fine grained matrix containing daubreelite, troilite, altered Si-bearing kamacite, perryite, schreibersite, oldhamite and albitic glass. Several chondrules contain relatively ferroan low-Ca pyroxene.

Geochemistry: Enstatite (Fs1.3±0.9Wo0.4±0.3, range Fs0.3-4.1Wo0.0-1.0, N = 19), forsterite (Fa0.3±0.1, range Fa0.3-0.4, N = 3), relatively ferroan low-Ca pyroxene (Fs13.4±3.8Wo3.0±1.1, range Fs11.4-19.1Wo4.2-1.9, N = 4).

Classification: Enstatite chondrite (EH3). The presence of relatively ferroan low-Ca pyroxene in addition to the dominant enstatite has been previously documented in EH3 chondrite Yamato 691.

Specimens: 24.83 g including one polished thin section at PSF; remainder with Mr. J. Whitcomb.

Itqiy EH7-an #1 – 5,63 g

1.115,32 $

To date, Itqiy is the only meteorite in the world classified as EH7-an.

It is an enstatite chondrite, an important class of chondrites that mostly exhibit sub-solar Mg/Si and refractory/Si ratios, oxygen isotopic compositions close to the terrestrial fractionation line and highly reduced mineral assemblages (containing little FeO, Si-bearing metal and sulfides of elements normally considered lithophilic).

This highly metamorphosed meteorite has a very unique texture !

The Earth seems to have been formed from celestial bodies whose composition is close to that of enstatite chondrites.

El Hammami H5 #1 – 382 g

570,73 $

El Hammami is one of the first meteorites found in the Sahara and which was traded.

It was found in Mauritania in 1997, and yet it was also sold under the name of Mhamid, in Morocco, because they are Moroccans

of this city which made the trade of it.

In 1997 November, Mr. Thompson traveled to Mauritania and collected six fresh-looking stones totaling ~200 kg (individual masses of 80, 51, 30, 26,

8 and 4 kg) at the foot of the El Hammami mountains in Mauritania (1000 km southwest of Mhamid, Morocco).

Some of the material looks weathered and rusts easily, but most of it is fairly fresh.

A legend tells that the most oxidized specimens are the ones that were in direct contact with the skin of the camels used to transport the specimens.

Orconuma H3-4 #7 – 2.8 g (Copie) (Copie)

118,91 $

The Orcunama meteorite fell in the Philippines in 2011.

It has been classified chondrite type H3-4.

A single stone of 7800 g covered with a dark fusion crust was discovered.

On the clear and sunny morning of March 7, 2011, three farmers (Fredo Manzano, Edgar Francisco Senior and Enrico Camacho Junior) in Orconuma, Bongabonga, Philippines were clearing their field when they were startled by six consecutive loud explosions. The sound of the explosions seemed to last for half a minute. At first they thought it was thunder because the ground was shaking. As they looked up to the sky, they saw a “burning red object with sparks coming out of it”, leaving a thick trail of smoke and making a characteristic hissing sound before it hit the ground. By their own admission, the farmers initially thought it was a bomb and considered that it might be “the end of the world.” They remember that the birds flew away immediately at the sound of the explosions. They went to look, and less than 10 meters away, they found a hole in the ground, surrounded by stirred up dirt and what looked like burnt grass. Inside the hole, about 1 m deep, they saw a stone object and, lacking tools, they used a piece of wood lying nearby and their bare hands to dig it up. Not knowing what this strange stone was, they started asking around, and showing the stone to the locals, but then they were afraid someone would try to take it from them. This fear led them to wrap it in a sealed plastic container before burying it underground for a year. They finally decided that no one would come looking for it, so they dug up the stone and stored it in Fredo Manzano’s closet for the next 8 years. In 2020, they were interviewed for a local TV newscast (later posted on YouTube with over 5 million views), and during the filming, the stone was visually examined by geologist Jocelyn Villanueva, who concluded that it might be a type of basaltic volcanic rock. The farmers, however, remained convinced that it could be a meteorite and hired Ramelle Baquil Ramirez to help them find a buyer. Subsequently in April 2021, with the assistance of an experienced tektite dealer (Carmelita Cepe), the stone was acquired jointly by John Higgins and Jasper Spencer.

NWA 13202 Chondrite Ung #1 – 4,13 g

653,96 $

NWA 13202 is a very particular meteorite, it is classified as an ungrouped chondrite.

Visually it does not look like any chondrite because it is very rich in metal.

It is a unique meteorite !

Writeup from MB 109:

Northwest Africa 13202 (NWA 13202)

(Northwest Africa)

Purchased: 2020 Jan

Classification: Ungrouped chondrite

History: A very dense, metal-rich specimen, found as two naturally-broken pieces which fit together, was purchased in January 2020 by Mark Lyon from a dealer in Zagora, Morocco.

Physical characteristics: The broken surfaces on both pieces are coated by rusty terrestrial weathering products. Polished interior surfaces exhibit dominant fresh metal (with minimal staining) and subordinate interspersed silicate-rich regions.

Petrography: (A. Irving, UWS and J. Boesenberg, BrownU) The specimen consists of two distinct interspersed components with overall proportions of ~75% metal and ~25% silicate-rich material. Metal-rich regions (up to 0.5 mm) are composed of 95% kamacite with 5% taenite, and contain fine grained metal plates ranging from 100 to 500 μm in diameter. Silicate-rich regions (up to 0.5 mm) contain a variety of chondrules (with apparent diameters ranging from ~100 to 1500 μm). Most chondrules are glass-bearing (PP, PO, POP and barred pyroxene types) but some are cryptocrystalline. Accessory phases in silicate-rich regions include kamacite, taenite, chromite, troilite, merrillite and chlorapatite.

Geochemistry: Olivine (Fa24.6±3.9, range Fa15.5-28.0, N = 16), low-Ca pyroxene (Fs15.8±1.4Wo1.5±0.9, range Fs14.6-19.6Wo0.6-3.5, N = 11), pigeonite (Fs14.8-15.1Wo8.3-9.1, N = 2), kamacite (Ni = 4.8-7.0 wt.%, N = 7), taenite (Ni = 16.5-21.3 wt.%, N = 3).

Classification: Chondrite (ungrouped, metal-rich). Paired with NWA 12273 and NWA 12379.

Specimens: 20.0 g including one polished slice at UWB; remainder with Mr. M. Lyon.

El Mrira 001 H4-melt breccia #1 – 21,7 g

148,63 $

El Mrira 001 is an ordinary H4 melt breccia chondrite discovered in Morocco in 2019.

What makes this meteorite special is its texture and its rarity; only 9 meteorites of this type classified to date.

El Mrira 001 28.467°N, 8.920°W

Morocco

Find: 2019 Jan

Classification: Ordinary chondrite (H4, melt breccia)

History: The specimens (total weight 6600 g) were found together in January 2019 in southern Morocco at 28.467°N, 8.920°W and purchased by Jesper Grønne in 2019 from a dealer in Agadir, Morocco.

Physical characteristics: A notable feature of these specimens is the presence of abundant spherical to ellipsoidal vesicles and larger vugs (up to 14 mm across) in the fine grained melt-textured matrix.

Petrography: (A. Irving, UWS and P. Carpenter, WUSL) Very fresh specimen consisting of equilibrated Type 4 chondrite clasts in a very fine grained matrix with prominent vesicles (some ellipsoidal and preferentially aligned). Lithic clasts are shock-darkened and consist of well-formed chondrules in a relatively coarse grained, recrystallized matrix containing relatively abundant kamacite plus taenite, troilite, merrillite, chlorapatite and chromite. Clasts have shock stage S4. The vesicular matrix contains distributed small silicate mineral clasts set in a partly glassy, melt-textured groundmass with dispersed composite metal+troilite spherules (up to 1.5 mm in size).

Geochemistry: Olivine (Fa18.5±0.3, range Fa17.9-18.9, N = 6), low-Ca pyroxene (Fs16.5±0.5Wo1.2±0.2, range Fs16.2-17.3Wo1.0-1.4, N = 5), subcalcic augite (Fs9.1Wo36.3), augite (Fs6.0±0.6Wo46.1±0.3, range Fs5.5-6.4Wo46.3-45.9, N = 2), plagioclase (Ab64.2An34.7Or1.1).

Classification: Ordinary chondrite (H4-melt breccia).

Specimens: 20.1 g including one polished thin section at UWB; remainder with Mr. J. Grønne.
