Silification Geology (OPALS) with Patrice Rey

Gems of lightning and shadows. Rainbow fossils. Underground tunnel homes. Mysterious sedimentary origins. Aboriginal dreamtime stories. Armored snails. Questionable song lyrics. It’s opals, folks. And world expert geophysicist and University of Sydney professor Dr. Patrice Rey is here to talk about why he left France to explore the geological mysteries of the Outback. Should you get an opal engagement ring? Can they get wet? What’s the difference between an Australian and Ethiopian opal? What was one doing in a Kenyan cave 3000 years ago? What’s a Kyoto Opal vs. opalite? And why was your great grandma named Opal?

(Cultural warning to Aboriginal and Torres Strait Islander listeners: this episode mentions names and stories of people who have passed.)
