Despite being dense in its pure state, where did the heavy element uranium become concentrated due to its chemical properties?

Answer

In the crust and upper mantle

Uranium has a high chemical affinity for silicates; therefore, it was swept upward with the rising silicate materials, leading to its concentration in the upper layers rather than sinking with the iron.
