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. |
