Walter,

O. Richard Norton's Encyclopaedia of Meteorites is
really good for defining this. Broadly, it's believed
to be the impact pressure required to create the
internal structure of the meteorite. Some minerals
simply cannot form below certain pressures for
example. Impact shock vein are caused by certain
pressures in certain minerals etc.
The shock features are likely dated to the time that
the meteoroid was formed (broken off it's parent
body)though some may be caused by subsequent impacts
in space

Can't recommend the book enough though. It's great for
the beginner prepared to do a little work.
