                NWA 2933 (L3.3 Regolith Breccia) with Black Inclusion 
                
                 Northwest Africa 2933 
                (NWA 2933) was found in the Sahara Desert, Africa as a single 
                stone weighing 511g. NWA 2933 has been classified as a very rare 
                L3.3 Regolith Breccia, with a Shock Rating of S2 and a 
                Weathering Level of W2. A regolith can be described as a mixing 
                of different compositions and/or petrologic stages with a fine 
                matrix at the surface of an asteroid, or moon, etc. This can be 
                discerned (especially under magnification) in the sample below 
                where there are areas of smaller brown/orange chondrules/matrix 
                set amongst the pale grey matrix. There are numerous unusual 
                chondrules and inclusions within this slice such as the large 
                obvious black inclusion at the bottom centre. This inclusion is 
                relatively featureless apart from a few small pieces within it. 
                These look like small chondrules or chondrule fragments. In 
                fact, these type of inclusions have been theorised to be heavily 
                altered pieces of CM or CI material with phantom chondrules. 
                This specimen is part of the Meteorites Australia Collection 
                (MA.05.0103).
