Bill MinarikA very colourful and entertaining talk this week from Dr. Inna Lykova
(Research Scientist and Acting Curator, Canadian Museum of Nature). She showed us the amazing minerals found at the fissure eruption of Tolbachik volcano, #Kamchatka (Mindat.org lists 371 valid minerals, with 153 type localities). These minerals seem to form in a complex chromatographic fumerole system.
