                NWA 2705 (Ureilite) - 3.2g Endcut with Interstitial Metal  Northwest Africa 2705 
                (NWA 2705) was discovered during 2005 in the Sahara Desert. A 
                tiny 30g  crusted and oriented shield-shaped meteorite 
                is all that was found. It has since been classified as a rare 
                Ureilite with a Shock Rating of S2 and is virtually unweathered 
                with a Weathering Level of just W0. NWA 2705 displays 
                beautiful green/yellow/orange olivine crystals which are 
                actually separated by black interstitial 
                carbon (Diamonds). There is also a large amount of fine grained 
                graphite inclusions in olivine and pyroxenes. The average values (vol. %) for silicate 
                analyses are - Olivine: 95%, Pigeonite: 3%, and Orthopyroxene: 
                2%. Within this particular endcut, it is also evident that there 
                is a small amount of metallic iron veinlets, webbing around the olivine 
                crystals like a tiny road-map. Some of the metal has fallen out 
                which probably occurred during slicing and polishing. The last 
                image indicates the metal in a magnified view as white specks 
                and lines trailing through the dark matrix. Virtually all 
                Ureilites have metal veinlets but they are quite low in Nickel 
                and are easily oxidised from weathering. For this reason, only 
                fresh Ureilites will still have these metal veinlets 
                present.  Only 5 pieces were 
                available to collectors after the type-specimen and 
                cut/polishing loses were taken into account. They were a 3.8g 
                and 3.2g Endcut along with complete slices weighing 2.9g, 2.7g 
                & 2.4g. This specimen is the 3.2g Endcut (2 of 5) and is part 
                of the Meteorites Australia Collection (MA.05.0099).
