Episode 418 - "I like the crystal habit"

What makes a mineral a favorite? In this fun and down-to-earth episode, John and Shannon swap stories about the minerals they love most — and why. Along the way, they unpack cool crystal habits, formation environments, fieldwork memories, and the aesthetic appeal of minerals from museum specimens to muddy boots. Shannon shares her appreciation for: Hematite – With its metallic luster and planetary significance. Goethite – A subtle but important iron oxide-hydroxide. Smithsonite – Beautiful colors and a fascinating history in ore geology. John counters with: Ulexite – “TV rock,” with fiber-optic properties that never fail to wow. Uraninite – A dense, radioactive reminder of geologic power and energy. Tourmaline – A colorful, complex favorite of mineral collectors and scientists alike. Fun Paper Friday James, C. W., et al.
