http://ThoriumRemix.com/ There's some chemical differences between thorium and uranium.

Bleached by water, U compounds were widely dispersed.

And having been scattered far and wide, U compounds today are found as complex, generally dilute deposits containing mixtures of tetra, penta and hexa-valent uranium.

Unlike uranium, tetra-valent thorium- and it's constantly tetra-valent- resists weathering.

Thorium thus remained concentrated where it first wound up- within easy reach.
