Abstract— Dengli is a highly weathered 243.5‐g chondrite that was found in 1976 in the Karakoom desert, Turkmenia. The meteorite contains olivine, high‐Ca and low‐Ca twinned pyroxenes, plagioclase, merrillite, cryptocrystalline material, and opaque minerals: metallic Fe, Ni, troilite, chromite. Based on the texture and the compositions of olivine (Fa 19.6 , n = 52, C.V. = 19.3) and low‐Ca pyroxene (Fs 18.2 , n = 27, C.V. = 17.0), Dengli is classified as an H3.8 breccia.
