The sixth podcast on www.cyclostratigraphy.org is by Margriet Lantink. In her 2019 Nature Geoscience paper, Margriet demonstrated a climate control on Banded Iron Formations from South Africa. In this podcast, she elucidates how cyclostratigraphy and radio-isotopic dating were both essential in coming to her interpretation. She also shares her vision on what's next in researching the early days of Planet Earth. The Intro music of this podcast is again an excerpt of a piece based on the North Atlantic Oscillation from the "Aphrodite's Dew" book and CD project by Arvid Tomayko and Sandro Montanari.
