7. Minerals past, present, and future
View through CrossRef
‘Minerals past, present, and future’ first considers a theory of mineral evolution that proposes the Earth has evolved through three eras subdivided into ten stages, with each adding to the total inventory of mineral species. They are the planetary accretion era (Stages 1 and 2), crust and mantle reworking era (Stages 3–5), and biologically mediated mineralogy era (Stages 6–10). What role did these minerals play in the emergence of life? Pressing concerns for the present and future are whether the Earth has enough mineral resources to support human life and the environmental impact of the extraction, processing, and utilization of mineral resources.
