You're right, I'm dumb, the graph is 0 at 10^6 Si. So rare earths are 1 million times more rare than Si. It's similar to copper and Nickel though

- pfdietz 4y agoNot a million times more rare, more like ~10,000 times. Also, Ni is more abundant in the oceanic crust than the continental crust. Lots of Ni in mantle rocks (peridotite is about 0.1% Ni.) It's interesting comparing the abundance of copper (and even more so, tin) and iron. It was a huge transition in resource availability when the iron age began.
