Thorium-uranium systematics require layered mantle

Uranium-thorium systematics provide important constraints on mantle dynamics. Of particular importance is the concentration ratio of thorium to uranium. This can be expressed as the mass concentration ratio of the two elements Cxh/Cu or the (molar) isotope ratio •c = 232Th/238U. Since 238U constitutes 99.21% of natural uranium and 23ZI'h ...
