I lava good volcano - with Dr. Elizabeth Kenderes

On today's show we have Dr. Elizabeth Kenderes, an igneous petrologist interested in the stories that lavas and igneous rocks may tell about how or why a volcano erupted (or didn't!). Hear about some weird volcanoes that drew her into the field as a student, what makes a good gemstone for jewelry, underground mines and drilling blast holes, and fluid inclusions - literal pockets of fluid trapped in solid, crystallized rock!
