Default Evolution of earth's minerals via plate tectonics?

This seems to be a borderline astronomy question.

Where can I find more on the subject below?
Anything on the net?...

A few years back, I found an article on the net
which said that the entire suite of minerals
which are found in the earth has been continually
evolving and increasing in variety. Ie: originally,
the very ancient earth was relatively poorer in
its minerals 'library', so to speak. But because
of the engines of plate tectonics and erosion,
among other processes, the relatively few ancient
minerals were cycled around through the crust
and mantle and altered, with new kinds developing
over time. I'd really like to know more about
this.

I suppose, to the extent that this is true, we
might expect to find that moons and planets with
little or no tectonic activity or erosional
processes, have relatively smaller suites of
minerals?

Thanks.
