Northwest Africa 4814 (NWA 4814)

NWA 4814 was discovered in the Sahara Desert in Northwest Africa during 2006 in the form of a single stone weighing 1120g. This visually spectacular meteorite was classified as a Rumurutiite chondrite breccia with a specific classification of R3-6. NWA 4814 has a Shock Rating of S3 and a Weathering Level of W3.

The photos below depict a meteorite with obvious clasts of different size and type. Some of the more notable are the darker ones with the plentiful array of small closely packed chondrules. These represent the primitive and unaltered material which formed the Rumurutiite parent body. The larger and lighter clast at the top centre of the first image shows a part of the same body which underwent metamorphism. Therefore the chondrules are less discernible and appear to ‘fade’ into the matrix. This specimen is part of the Meteorites Australia Collection (MA.08.0006).
