Hello which Planet Composition(/s) should i look for to find certain minerals?
Such as Arsenic, Mercury, thechnetium, etc..?
All planets i have visited so far (even ice ones) give all the same stuff, from Iron, zinc, etc..
I know that you can find meteorites an such on the surfaces, but they mostly contain the same common stuff. so are they planet specific? or is it just luck to find the more rarer minerals?
