TARDA is a meteorite that fell in Morocco on August 25, 2020. Writeup from MB 109 :<\/u><\/p>\n Tarda<\/strong> 31\u00b0 49′ 35″N, 4\u00b0 40′ 46″W<\/p>\n Morocco<\/p>\n Confirmed fall: 2020<\/p>\n Classification: Carbonaceous chondrite (C2, ungrouped)<\/p>\n Classification <\/strong>: (C. Agee, UNM<\/em>; K. Ziegler, UNM<\/em>; A. Irving, UWS<\/em>; L. Garvie, ASU<\/em>; D. Sheikh, FSU<\/em>; P. Carpenter, WUSL<\/em>; H. Chennaoui Aoudjehane, FSAC<\/em>; M. Zolensky, JSC<\/em>; P. Schmitt-Kopplin, HZM<\/em>) 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 \u03b418<\/sup>O-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, \u039417<\/sup>O 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.<\/p>\n Specimens <\/strong>: 18.4 g including one polished thin section and one polished thick section at UWB<\/em>; 21g and one polished thin section at UNM<\/em>; 7 g provided by A.

\nThis meteorite has been classified as C2 ungrouped, a rare type of very primitive carbonaceous.
\nTagish lake is a meteorite of the same type and sells for over 1000 euros per gram.
\nThis meteorite is composed of many very small fragments, beautiful pieces with crusts are rare.
\nIsotopic analyses show that some pieces have <\/span>values <\/span>close to<\/span> CI chondrites, <\/span>and other pieces <\/span>have Yamato<\/span> (CY)<\/span> values.<\/span>.
\nAn important meteorite at the scientific level in the years to come.<\/span><\/p>\n
