Jrifia Boujdour CM2/CO3 #3 – 13,2 g

356,71 $

Jrifia Boujdour is a carbonaceous meteorite.
But what makes it special is its analysis.
Several laboratories worked on this meteorite, and obtained different classifications, once CM2 (NWA 10574) and the other time CO3 (NWA 10580).

Writeup from MB 105:

Northwest Africa 10574 (NWA 10574)

(Northwest Africa)

Purchased: 2016

Classification: Carbonaceous chondrite (CM2)

History: Many small meteorite fragments were bought in 2016 from the Moroccan meteorite dealer Hamza Lharbi in Guelmim, Morocco.

Petrography: The meteorite shows an almost black interior and is composed of about 0.1-0.3 mm chondrules, chondrule pseudomorphs, mineral fragments and rare CAIs often surrounded by fine-grained accretionary rims set into an abundant fine-grained matrix. Main matrix phases are phyllosilicates, carbonates, and pyrrhotite.

Northwest Africa 10580 (NWA 10580)

(Northwest Africa)

Purchased: October 2015

Classification: Carbonaceous chondrite (CO3)

History: Purchased from a Moroccan dealer, October 2015.

Physical characteristics: Many identical appearing stones. Shiny, black to dark brown, smooth weathered exterior with very small chondrule pits; saw cuts reveals numerous small chondrules and a few small CAIs set in a dark-brown matrix.

Petrography: (C. Agee, UNM) Microprobe examination of a polished mount shows numerous chondrules, many fragmental or irregular, most in the size range 50-200 μm, a few up to 600 μm. Scattered metal/sulfide blebs, fine-grained matrix makes up about 50% of this meteorite. Most chondrules appear to be Type I with forsteritic olivine, enstatitic pyroxene or aluminous diopside. Very few Type II chondrules were observed.

A mystery still not cleared up.

TARDA C2 Ung #21 – 9,8 g

2.734,78 $

TARDA is a meteorite that fell in Morocco on August 25, 2020.
This meteorite has been classified as C2 ungrouped, a rare type of very primitive carbonaceous.
Tagish lake is a meteorite of the same type and sells for over 1000 euros per gram.
This meteorite is composed of many very small fragments, beautiful pieces with crusts are rare.
Isotopic analyses show that some pieces have values close to CI chondrites, and other pieces have Yamato (CY) values..
An important meteorite at the scientific level in the years to come.

Writeup from MB 109:

Tarda 31° 49′ 35″N, 4° 40′ 46″W

Morocco

Confirmed fall: 2020

Classification: Carbonaceous chondrite (C2, ungrouped)

Classification : (C. Agee, UNM; K. Ziegler, UNM; A. Irving, UWS; L. Garvie, ASU; D. Sheikh, FSU; P. Carpenter, WUSL; H. Chennaoui Aoudjehane, FSAC; M. Zolensky, JSC; P. Schmitt-Kopplin, HZM) Carbonaceous chondrite (C2-ungrouped). The bulk mineralogy is consistent with a petrologic grade 2, based on the predominance of smectite and serpentine together with the presence of anhydrous mafic silicates, AOA, and chondrules. The oxygen isotopes give a bimodal distribution of the δ18O-values, with one group having values somewhat like those of the CI chondrites, and the other group like values for the Yamato-type (CY) carbonaceous chondrites (King et al., 2019). However, Δ17O values are lower than those for CI and CY chondrites, and plot below the TFL. These isotopic values do not overlap with those of any established carbonaceous chondrite group, hence the ungrouped designation.

Specimens : 18.4 g including one polished thin section and one polished thick section at UWB; 21g and one polished thin section at UNM; 7 g provided by A. Aaronson and 6 g provided by J. Redelsperger at FSAC; 20 g at the Ministry of Energy, Mines and Environment, Rabat, Morocco provided by A. Aaronson; total 628 g with A. Aaronson (including 99 g, 82.4 g and 52.6 g stones); 540 g with M. Farmer and A. Karl, 260 g with J. Poblador; 480 g with D. Dickens; 145 g with M. Oulkouch; 146 g with J. Redelsperger; 31 g with B.

AL HAGGOUNIA 09 Eucrite #6 – 24,7 g

234,83 $

In April 2013, I prospect for meteorites in Morocco with a group of friends.
After an unsuccessful search for the Martian meteorite NWA 7397, we met a group of meteorite hunters who took us to the site of a new meteorite discovery on April 18.
The day before, a meteorite of 219 grams was found, the meteorite hunters thought at first that this meteorite was a lunar meteorite.
It finally turns out that this meteorite is not a lunar meteorite but an eucrite.

Other fragments will be discovered later including the supposed main mass (332.85 grams) on April 24, 2013 by Lahcen Oukhouya meteorite hunter and native of Smara.
I was able to acquire the main mass of this fall, as well as 8 other fragments through Ali Oulmaleh (meteorite dealer in Erfoud) and Mohamed Elguirah (meteorite hunter in Tan Tan).
This meteorite was found 120 km northeast of Laayoune in the Western Sahara, in a place called Chwichiya (little fez) in reference to the mountain seen in this region in the shape of a fez.
Chwichiya is an area rich in meteorites, and in particular achondrites, 4 different achondrites have been discovered within a radius of 6 kilometers!

This meteorite is a brecciated eucrite, composed of 11 pieces for a total of 1038 grams. This meteorite has the particularity to have two different textures.

Petrography: Breccia with coarse basaltic clasts in a fine-grained matrix. The matrix has a doleritic texture with plagioclase grain size of several mm. Dominant minerals are exsolved pyroxene and mm-sized calcic plagioclase laths. Minor phases include chromite, silica, Ca-Phosphate, troilite and metal.
