“Crown of Flame”

Chondrite, unclassified
Found near Enafor Rig # 40
Taghit, Béchar Province, Algeria
Find: October 2016
TKW: 4.080 g (one mass)
Individual: 4,080 g

This remarkable stone meteorite was found by Sidi Hamada in the vicinity of Enafor Oil Rig # 40, in Béchar Province, Algeria, in October 2016.

 

The pentagon-shaped mass shows a convex breast side, and a rather flat trailing section. In cross section, the meteorite has an airfoil profile. The trailing surface is shaped by two planar fractures that show only minor traces of atmospheric ablation.

 

Fluted regmaglypts in radial array are framing the breast side like a crown of flame. Their apparent point of origin is located slightly outward the post-fall edge of the mass (a), where the meteorite has the least diameter. This, however, would indicate a flight orientation with the center of gravity trailing instead of leading – an orientation which is highly improbable and unlikely to result in aerodynamic stability.

 

Since surface texture and atmospheric sculpting of the mass are controlled by a stable and lasting orientation of the meteorite during its ablative flight, a flight orientation with the center of gravity in the lead has to be assumed. Thus, the regmaglypts and ablation furrows at the N-surface‘ B-edge must be understood as directed rimwards towards „a“, rather than conversely.

 

This is an well-preserved and exceptional example of a distinctly oriented stone meteorite in the multiple kg-range.

SARATOV

Stone, chondrite, L4, W0
Saratovskaya Oblast, Russia
Fall: September 6, 1918
TKW: ~1 MT
Fragment: 2,554 g

October 6, 1918, about 5:00 in the afternoon: Startled by a bright flash, peasants all over the northern counties of Saratov Oblast looked up to what appeared to be a group of fireballs coming from the Samara Oblast and moving to the west in a shallow arc, impressively highlighted by the sinking sun. The sighting was followed by what was described as “a powerful roar”, perceived by some as the advent of the Last Judgement. Two large fragments of the meteorite, reportedly weighing 500 kg each, were later recovered from a depth of 2 meters, one near the village of Dongus in Volsky District, and the second close to a settlement near Petrovsky. According to the reports, a third mass that was seen to fall in the Khvalynsk area on the border of Samara Oblast remains missing to the present day. This specimen is a 2.5 kg Fragment from one of the 500 kg pieces dug out from the Impact pits. Specimen is uncleaned, red Russian soil is still adhering to the fresh fusion crust.

Stone, chondrite H5, S2, W0
Bassikounou, Hodh Ech Chargui, Mauretania
Fall: October 16, 2006, 04:00 hrs
TKW: > 93.85 kg
Individual 581.0 g

„A fireball was witnessed in the area, but no records of the direction of movement were recorded. A single stone of 3,165 g was found by A. Salem El Moichine, a local resident, on the same day at 13:00 hrs local time. The sample for classification was provided to NMBE by M. Ould Mounir, Nouakchott, who obtained it from his cousin who recovered the meteorite. According to S. Buhl (Hamburg, Germany), more than 20 specimens were later recovered by locals and meteorite finders. These finds define a 8 km long strewnfield. The total recovered mass is 46.00 kg.“ (Meteoritical Bulletin, no. 92). This is a pristine wedge-shaped fragment with 90 percent fusion crust and distinct flowlines on its largest surface. Flowlines and frothing can also be seen on one of the trailing surfaces. One fractured surface shows tertiary fusion crust developed at the latest stage of the hot flight.

Northwest Africa 7707

Stone, chondrite, L6, S3, W1
Northwest Africa
Find: 2012
TKW: 2.441 g
Individual w. small cut surface: 2,343 g

Heavily sculpted and regmaglypted chondrite with well preserved fusion crust. The 2.3 kg chondrite is 90 % coated with dark black fusion rind and bears the marks of a violent atmospheric ablation in the shape of distinct regmaglyps. A small corner shows effects of mechanical abrasion (corrasion), indicating it was recovered from an environment with abundant wind-borne sand. The Absence of desert varnish as well as the very low weathering degree points to a relatively recent fall event. The small cut surface, resulting from the removal of the classification sample, reveals intense shock veining, indicating a catastrophic impact event on the meteorite’s parent body. True museum-grade display specimen.

Museum grade display specimen

The specimen up for sale is the main mass of NWA 7370. With its well-preserved texture, bottle-green matrix and olive drab patina this rare HED achondrite is an exceptional showpiece and unique collection specimen.

Northwest Africa 7370

Stone, achondrite, diogenite-olivine
Gao, Mali
Find: May 2009
TKW: 2.29 kg
Half individual: 426.0 g

 This is one of only a handfull meteorites that are classified as olivine-, or harzburgitic diogenite (greater than 40 vol% olivine). Out of the 419 diogenites presently known, only ten qualify as harzburgites (olivine + magnesian orthopyroxene in contrast to conventional / ferroan orthopyroxene diogenites). NWA 7370  is also quite high in chromite (15 wt%). Chromite can be seen as black notches protruding from the crust. Due to its higher melting point, the chromite resisted atmospheric ablation better than the matrix.

Write up (Meteoritical Bulletin 101):

History: Four meteorites were discovered by an anonymous finder east of Agaraktem, Mali, in May 2009.

Physical characteristics: Four almost complete individuals totaling 2290 g.

Petrography: (R. Bartoschewitz, Bart) Polycrystalline olivine clusters (~50 vol%) of idiomorphic to hypidiomorphic cystals (<1 mm, average about 0.1 mm) distributed in schlieren-like bands within a matrix of xenolithic to hypidiomorphic pyroxene grains (about 1 mm), with rare intergranular feldspar. Chromite and metal occurs dominantly within pyroxene and olivine grains.

Geochemistry: (R. Bartoschewitz, Bart; P. Appel, B. Mader, Kiel) Pyroxene Fs23.8-25.4Wo2.0-4.4, olivine Fa29.3-30.3, feldspar An76-83Ab1-5. Chromite Al2O3 = 14.4-15.4, TiO2 = 0.9-1.1, MgO = 4.1-4.8; Kamacite Ni = 0.3-1.1, Co = 0.7-0.9 (all in wt%).

Classification: Olivine diogenite, S1, very fresh

Norton County

Stone, achondrite, aubrite
Norton County, Kansas, USA
Fall: February 18, 1948
TKW: 1.1 MT
Fragment: 27.3 g

At about 4 p.m. on February 18, 1948, hundreds of people witnessed a brilliant fireball in the clear afternoon skies above Colorado, Kansas, and Nebraska. Several people heard loud explosions, followed by a roaring sound like the noise of a jet engine. In the smoke train behind the fireball, puffs of smoke appeared where the large meteorite that was streaking across the sky broke apart in smaller fagements. In the following days and months, hundreds of stones were recovered from a large area on the Kansas / Nebraska border, in Furnas County, Nebraska and Norton County, Kansas. The meteorite became known as the Norton County Meteorite.

This is a pristine, unweathered fragment coming from the University of New Mexico’s Meteorite collection. Specimen bears the handwritten collection # N 533. Original University of New Mexico Label included.
