Catalog of 208 human-caused minerals bolsters argument to declare ‘Anthropocene Epoch’

2 March 2017

Now we know that as many as 29 carbon minerals originated with human activities, of which 14 have no recorded natural occurrences. It is fair, therefore, to consider the 14 as the youngest carbon mineral species. Among the 14, candidates for the very youngest include a dozen minerals related to uranium mines.

Another notable carbon-bearing mineral is tinnunculite, determined to be a product of hot gases reacting with the excrement of the Eurasian kestrel (Falco tinnunculus) at a burning coal mine in Kopeisk, Chelyabinsk, Russia. It was subsequently discovered also on Russia’s Mt. Rasvumchorr—an entirely natural occurrence.

Tinnunculite is one of eight new minerals identified as part of the Deep Carbon Observatory’s Carbon Mineral Challenge, launched in 2015 to track down an estimated 145 carbon-bearing minerals yet to be formally recognized. The IMA recognized tinnunculite as a mineral in 2015.
