Hi, all,
 
There have been several inquiries regarding the details of the chondrite portion in this meteorite since I posted the first photos.
 
For anyone interested, I've added a few photos of the chondrules at the end of the album.
 
Metal is evident in some, distinguishable from the light glare off the alcohol needed to take pictures of the exterior relief.
I don't have the equipment or skills to do without the alcohol to capture the details. I use a cheap, 6 mp Casio nuzzled up to a microscope.
(photography tips welcomed!)

> Dear List,
>
> I've dusted off this stone out of my box of NWA Unclassifieds, and I think it's worth sharing.
>
> It has an interesting achondritic inclusion making up abut one third of the 97.2 gram mass, which appears similar to a basalt with skeletal ilmenite crystals.
> The achondritic portion is not magnetic, and the chondritic portion is moderately magnetic.
>
> The series of pictures can be viewed here:

> A second click on each photo opens full resolution.
> Both the scales are millimetre.
> All are wet with isopropyl alcohol for enhancement of details.
>
> I suspect the copper-coloured features (clearest in pics 6 and 9) to be oxidised troilite.
> Most are 1 - 2mm dia.
>
> If memory serves, didn't someone else on the List post pics of a similar matrix, within the past year?
>
> Opinions welcomed.
