[meteorite-list] Shocked or not shocked?

[Horace Heffner]

Question: does this basalt look like it is shocked?

Optical 40x and 100x.

Electron micrograph 300x:

These small multi-oriented and broken grain features seem to match  
some shocked material photos here:

At least one local granite rock looks like this, even in much larger  
magnification:

The above, to my untrained eye, looks to be not shocked, while the  
first set of photos show shocked basalt. The question is, do the  
first set of photos actually show a basalt that is shocked?
