Welcome to CoreFacts, where we're always short on time and big on science. I'm Steve Sobieszczyk. Today's question goes out to all you geologists and geology teachers out there.
What is Fool's Gold?
Fool's Gold can be one of three minerals: pyrite, chalcopyrite or biotite. The most common mineral mistaken for gold tends to be pyrite, although chalcopyrite may also appear gold-like. In general, the pristine form of biotite is fairly recognizable, however, weathered biotite can be easily confused for flake gold.
