Northwest Africa 5245 (NWA 5245)

NWA 5245 was discovered in the Sahara Desert during 2007 as a single stone weighing 418g. This fascinating meteorite was classified as an extremely rare unbrecciated R3 chondrite with a Shock Rating of S2 and a Weathering Level of W2. Most of the Rumuruti Chondrites are heavily brecciated with mixed petrologic grades ranging from 3-6. They all represent surface regoliths from their parent-body/asteroid which apart from their mixed grades, is also evident from xenolithic inclusions and higher levels of noble gases from the solar wind. This type-3 meteorite is a rare example of complete primitive and relatively unaltered material which formed the Rumuruti parent-body. This specimen is part of the Meteorites Australia Collection (MA.08.0007).
