HI Steve and welcome to the Meteorite List. I've
got only a two year head start on you. And I can assure you that if you
stay "tuned" you'll soon be quite able to decern a meteorite from an rock of
earth origin.
Terrestrial rocks, like the ones whose pictures
you've supplied, do indeed contain evidence of the tumultuous, tortuous
igneous and metamorphic processes that formed them.
Intrusions of molten material under intense
pressures leave their unmistakable signatures.
Impact shock viens look suspiciously similar but
the very texture of your rocks belie their origin.
Stick around and the three categories, iron,
stoney-iron and stoney meteorites will eventually "jump" out at you [98% of the
time]
