Jrifia Boujdour CM2/CO3 #2 – 7,87g

219,97 $

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 #19 – 0,34g

141,49 $

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.

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.

The Tissint meteorite fell on July 18, 2011 in the region of El Aglâb, in eastern Morocco, near the town of Tata.
It is the nomads who told the scientists that in the early morning of Sunday, July 18, 2011, they were awakened by a strong detonation as well as the military present in the area.

Tissint is a Martian meteorite classified as shergottite.
A Martian meteorite fall is observed on Earth about every fifty years, so it is a very rare event on the scale of a human life.
The Tissint fall zone is perfectly located with gps points and has been studied by Moroccan scientists.
