[meteorite-list] what is this, really

1)  In addition to not having a fusion crust, the object is 
suspiciously non-lunar in that the clasts are too much all the same 
size.  Lunar regolith breccias are the closest lunar analogs to 
terrestrial sedimentary rocks, and there is often a superficial 
resemblance.  In many (but not all) terrestrial sediments, however, 
wind and water processes lead to size sorting so that the clasts are 
all about the same size.  There are no such sorting mechanisms on the 
Moon.  I've called this a "fractal" effect - it doesn't make any 
difference what scale you look at a lunar regolith breccia, it always 
looks the same.  To me, in the rock in the photo (asphalt?), there 
don't seem to be enough big clasts or small clasts, as, for example, 
in ALHA 81005:

I've never heard of "meteorite expert" mentioned in the blurb.


2) Regarding text of Pluto news release: "Although astronomers 
applauded after the vote, Jocelyn Bell Burnell -- a specialist in 
neutron stars from Northern Ireland ..."

How many neutron stars are there in Northern Ireland?
