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.
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. Hoefnagels.

NWA 14809 is a carbonaceous meteorite of type CK5 of only 31 grams.
The reference fall is the Karoonda meteorite that fell in 1930 in Australia.
Writeup from MB 111 :
Northwest Africa 14809 (NWA 14809)
Algeria
Purchased: 2021
Classification: Carbonaceous chondrite (CK5)
History: Found in Algeria. Bought by Jean Redelsperger from Mohamed Elguirah in 2021.
Physical characteristics: Dark fragments.
Petrography: (J. Gattacceca, CEREGE) Chondrule with average apparent diameter about 800 µm set in a recrystallized matrix (grain size 15 µm). Olivine is the dominant mineral. Magnetite and sulfide are abundant in the matrix and chondrules, sometimes as composite spherical grains up to 200 µm.
