In this episode, Jesse and Chris follow up on the K-T Extinction episode from last week. Why is Iridium so important in this story? Our show notes summary is below.
Why is Iridium identified in these layers?

  • Well, it’s higher in meteorites - but not really high.
  • Why is it higher in meteorites though?
    • It’s not actually high in meteorites, it’s low in the Earth’s crust! Very very very low.
  • Yet, Earth is made of meteorites, so where did the Ir go?
    • Most of it is in the core and we talk about why.
  • Very rare on the surface of the Earth - only three metric tons mined and used yearly
    • The most corrosion resistant substance known - even at high temperatures
    • If it's so corrosion resistant, what is it used for?
