Transcript of Tungsten is gorgeous!

Welcome!
How to develop a new method
Analyse as many samples as possible
Tungsten yeah!
Earth's core formation
Chronology of the accretion and early evolution of planetary bodies
Double Spike technique

Column Chemistry
Modified after Sahoo et al., 2005
Tungsten stable isotopes are great!
You gonna looove them
Sorry, too late to leave... you have to listen to the whole talk now
Whats next?
Why is tungsten so important?
