Item for auction is a 3.67g individual of a pallasite meteorite found in North West Africa in 2010, with 170g of material received. A pallasite is a type of stony-iron meteorite that consists of cm-sized olivine crystals of peridot quality in an iron-nickel matrix, and to me are like the jewels of the meteorite world. Dr Anthony Irving classified this meteorite, noting the primary interstitial metal in this specimen has undergone complete terrestrial weathering leaving remnant fragments composed of fresh olivine (Fa12.9-13.3.9; FeO/MnO = 39.0-43.9) with accessory chromite (containing inclusions of kamacite and troilite). This endcut is loaded with olivine, clearly visible by naked eye, and also contains remnants of its iron-nickel matrix in the cut face polished to a mirror finish. Currently theory is that pallasites are impact-generated mixtures of core and mantle materials, and are quite rare. Only 61 are known to date, including 10 from Antarctica, with only 4 being observed falls. Pallasites from the hot deserts of Africa are rarer still, which would make this olivine encrusted jewel a perfect addition to your collection.
