<<I suppose we have a "definition" problem here. I'd say that lava
flows per se do not contribute to concentration of specific
minerals to any significant degree. At best they probably give
you access to some of the heavier core material which would have
a somewhat different composition of heavier elements.


If I understand some basic geochemistry (which I may not) the black regions
of the moon, called seas, are regions of basalt; which I believe is a
volcanic residue. Could the moon have been volcanic at one time, early on? I
should think so, simply because that was one of the apparent, traits of all
medium to small bodies of the early solar system, so why would the moon be

As far as meteorite impacts, I agree with your image of meteors striking
hard, and smashing through a recently cooled lunar crust to release lava. Why
does the childhood image of hot 'Chicken Pot Pies" come to mind? Summing it
up, I still contend that finding a plenitude of minerals to produce
industrial contrivances, will be fairly easy on the moon, whether the
material was originally lunar, or imported from the asteroid belt a billion
years ago.
