Cosmic Origins of Uranium - World Nuclear Association
It is likely that since about 2.5 billion years ago injections of uranium into the mantle have been effective in the reduction of the thorium to uranium ratio on an (upper) mantle-wide scale. An additional net effect is the selective reinjection of uranium as opposed to lead - which is mostly stripped out in subduction zones and returned immediately to the crust - into the mantle.
