Abstract– Among the several hundred, mostly small meteorite fragments, recovered within the Almahata Sitta strewn field, one fragment (MS‐CH), weighing 5.68 g, was detected that represents a new type of chondritic meteorite. The detection of short‐lived cosmogenic radionuclides clearly indicates that this chondrite fragment results from a fresh meteorite fall consistent with the Almahata Sitta event in October 2008. The fundamental mineralogical characteristics of the Almahata Sitta fragment MS‐CH can be summarized as follows: (1) the almost equilibrated olivine has high Fa contents of about 36 mole%. The fragment is of petrologic type 3.8 ± 0.1; (2) the metal abundance of the rock is on the order of 2.5 vol%; (3) the mean chondrule size has been determined to be roughly 450 μm; (4) point‐counting and imaging indicate that the matrix abundance is approximately 45 vol%; (5) Cr‐spinels have much lower TiO2 concentrations than typical spinels within R chondrites; (6) calcium‐aluminum‐rich inclusions are spinel‐rich and severely altered having abundant Na‐ and/or Cl‐rich alteration products. Spinel also contains significant concentrations of Fe and Zn; (7) magnetites and platinum‐group element‐rich phases (sulfides, tellurides, and arsenides) characteristic of both R and CK chondrites were not found in fragment MS‐CH; and (8) the mean oxygen isotope composition of three small fragments of Almahata Sitta MS‐CH is δ17O = +4.35‰, δ18O = +4.94‰, and Δ17O = +1.76‰. The oxygen isotopes relate MS‐CH to R chondrites. No established chondrite group having all these characteristics exists.
