Unclassified Australian Iron - 277g Oriented Nosecone Individual

Here is a text book example of a highly oriented shield shaped or 'nose-cone' iron meteorite. This specimen has undergone a degree of weathering and is in 'as found' condition with a natural desert patina. While it looks like most of the original fusion crust is no longer present, the shape of the specimen is clearly discernible.

From above, it has a slightly 'squashed circle' shape and from the side a domed, conical appearance which is just offset from centre. The trailing side has a slight subsidence towards the centre and shows a bumpy surface with what appears to be small shallow regmaglypts (or the remnants of). The leading side is smooth and rounded towards the centre but as you move towards the outer edge, there are small shallow elongated regmaglypts which graduate in size. and radiate from the centre towards the outer edge.

It was found in one of Australia's dry desert regions but while on the ground it seems to have developed a layer of caliche or something similar to it on parts of the surface. Particularly in the small regmaglypts which a careful cleaning later on should help to define again. This specimen is part of the Meteorites Australia Collection. (MA.05.0017)
