The NWA 1109 Meteorite – Polymict or Something

The Meteoritical Bulletin database lists NWA 1109 as a polymict eucrite – at least a 2.54 kilogram portion of the find was classified that way. I know that in 2002 and 2003 some material was sold as NWA 1109 howardite. For some of the discussion of Eucrite versus Howardite you can Google NWA 1109 howardite.

There are more than 20 different basaltic textures in this meteorite according to Adam Hupé. Here is a small sample.


And some frothy fusion crust.
