Description: Item for auction is a 9.93g fragment of NWA 4482 pallasite meteorite, that was found in Algeria in 2006, with >5.81kg of material TKW. *This particular specimen belonged to Ryan Dillon, and is a fairly flat fragment with a window ground and polished to a mirror finish to reveal the internal structure of the pallasite. Olivines in the window displays translucence and sparkle, while all metal phases have weathered into iron hydroxides. There is a large olivine inclusion that protrudes out of the fragment and acts as a mineralogical ‘kick stand’ to hold the piece upright while on display. The meteorite consists of dark, magnetic fragments containing yellowish-green silicate in a dark brown matrix. Petrography consists of large olivine grains (up to 8 mm across) with interstitial, porous, banded iron hydroxides enclosing sparse angular grains of terrestrial quartz, and accessory chromite, schreibersite and fresh metal (both kamacite and taenite). Olivine (Fa12.2-13.0, FeO/MnO = 41.1-42.5). Oxygen Isotopes: (D. Rumble, CIW) analysis of acid-washed handpicked olivine by laser fluorination gave δ18O = 3.65, δ17O = 1.72, Δ17O = -0.198(all in ‰). The meteorite is classified as a Pallasite (main group). This specimen comes with a Big Kahuna Meteorites Certificate of Authenticity. Scale cube is 1cm on each side and not included.
