Hi, Ginger:
Here's my two centavos: The idea of collecting micro-meteorites in rain
gutters has been floating around since the 1950s at least. I recall reading
an Isaac Asimov science-fact article about it in an old issue "Fantasy &
Science Fiction" magazine.
My guess--and I never actually looked at gutter detritus under a 'scope--is
that between the asphalt-fiber glass roof shingle debris and organic matter
which collects in gutters (unless you have a slate, metal or terra cotta
roof which might produce a distinctive erosional product(?)), it should be
somewhat "easy" to identify one--depending on having the luck of finding
particles in your gutter. I am skeptical that your gutter would be brimming
with the stuff (in fact I know it isn't). But if you search regularly after
rains over a long period of time, you may turn up something (irons would be
easy to spot I should think).
