Aug 19, 2020   RC reviews evidence for nanodiamonds in the Oklahoma Panhandle, with a hint at a more recent and local impact event, and in the eastern margin of the Greenland Ice Sheet. Can nanodiamonds be produced terrestrially? A chart of the Volcanic Explosivity Index leads RC to talk about ash from Mount St. Helens that has been found and dated within the Scablands floods’ rhythmites, and how those were the basis for the theories of repeated Lake Missoula dam-break outburst floods.  Then we get into the just-released paper that links the micro-proxies to volcanic eruptions and credits coincident endogenic processes for the Younger Dryas cooling episode, and because the authors do nothing to negate or refute the evidence for a YDB impact, they have a long way to go to prove their case and extrapolate the evidence from Hall’s Cave to the entire planet.  Kosmographia Ep042 The Randall Carlson Podcast with Brothers of the Serpent – Kyle and Russ, Normal Guy Mike and GCREX admin Bradley, from 08/03/20.
