NWA 2711 / Northwest Africa 2711

NWA 2711 was discovered in the Sahara Desert, Northwest Africa during 2004 in the form of a single completely crusted stone weighing just 433g. It was classified as a Mesosiderite with a Shock Rating of 1 and a very fresh Weathering Grade of just 1 also.

NWA 2711 has been described as a unique Mesosiderite and the classification states that "the specimen contains a relatively even distribution of metal and silicates with coarse orthopyroxene grains with margins that are recrystallized and contain numerous Merrillite inclusions. The matrix is recrystallized." In the photographs below, there are the above mentioned coarse-grained orthopyroxene grains/crystals which are interstitial to the metal grains. This specimen is a 10.8g fresh crusted partslice and is part of the Meteorites Australia Collection (MA.05.0121).
