Hello jj,
Although I am curious about the Albion iron, and I even remember a
discussion I had with Russ Kempton about it before he published his
Centerpiece article about it, my interest is somewhat diluted by the
overwhelming number of anomalous irons and unusual inclusions.  While we
use 12 recognized chemical classifications for iron meteorites, there are
dozens of anomalous irons that, by definition, defy our current
classification system.

One specimen I do have a serious interest in is the Laguna Manantiales. On
Friday, I was studying a slice of the Laguna with a local planetary
geologist. The Laguna has many unusual features, mineral regions, and
boundaries. Some inclusions have rims, some do not. There seems to be
evidence for impacts and reheating, and there are many hexahedrite-like
inclusions in this octahedrite. To me, this single meteorite is like having
a small collection of different iron meteorites all in one slice.

As the Albion story evolves, I imagine we will again have to rethink our
understanding of iron meteorites and their formation. In other words,
science as usual.

Cheers,

Martin
