Iron Meteorites: Science Chat Video Education, Meteorite Classifier, Tarda CM2-ung, Franconia Hunt

Описание: A replay of the 10-14-2020 Topherspin Meteorites weekly hangout focused on Iron meteorites. You can join us live any week. The details are below. How about subscribing and telling a friend about us?

At 1hr:45min Daniel Sheikh (of FSU) joins the conversation with details about the newly classified Carbonaceous Chondrite named Tarda. It was published to the MetBull just moments earlier. Tarda is the new witnessed C2-ung fall from 8-25-20 near Errachidia, Morocco. This one is rich with Kamacite and shows signs of both the CI and CY groups. Teams of meteoricists partnered to get this one understood enough to publish, including Daniel. The studying will continue.

Group Discussion Topics:
• Iron meteorite chemistry, Kamacite & Taenite descriptions, Classes, Grain boundaries
• Iron meteorite structure: Neuman Lines, Widmidstatten Patterns, Grain / Crystal sizes, Kamacite bandwidth, Hexahedrites, Octahedrites, and Ataxites
• Silicated Irons as a transitional class
• Iron protection discussion: lacquer choice and application, Paleo Bond? Candle wax?
