Any special nomenclature for this ?

Got a nice slap of a NWA H4.
Wonder if feature like this larger "chondrule" has any special nomenclature?

Your specimen has some radialness to it from some of the different grains, but only with some imagination.
I'm really surprised that with over 200 views that someone could not say "yes", "no", or whatever. I'm only a novice at this so take my response with some chondrule grains.

I've being digging in the literature and I came up with this:
Radial pyroxene chondrule, a compound chondrule, which was formed by a collision with a second, still plastic chondrule.
Found is this book:
Chondrule formation and accretion processes in the early solar nebula - Clues from noble gases in different constituents of unequilibrated chondrites
Page 24, Examples from Krymka, Photo B, left
I have no idea if it's pyroxene
Another photo with much better white balance.
(I really need to rebuild my USB microscope with daylight LEDs)

Norton's "Field Guide to Meteors and Meteorites", what a great book. Just finished reading it.
