The Anthropocene Minerals

Roughly 2.4 billion years ago a great deal of oxygen arose in our atmosphere, causing the number of minerals to skyrocket from around 2,000 to 5,000 with the addition of so many oxide versions. Hazen’s work now shows human events trump that so-called Great Oxidation Event, which was previously the largest known increase in minerals (taking the broad sense of the term). “There are so many things that we produce that are mineral-like that we have really changed the sedimentary horizon in which we are now living,” Hazen says.
