[meteorite-list] NWA basalt?

[Phil Morgan]

I found an odd little stone in a batch of unclassified material.  Most
of the non-meteoritic material I've culled out in the past hasn't
really resembled basalt like this one.

Slight attraction to a magnet and studded with what I assume to be
very clear little blobs of olivine.

I posted a couple of pictures here:

What is the general geology of the area and is something like this common?

Thanks,
Phil
