A calculation shows that the thorium-230—uranium-238 disequilibrium in MORBs can be attributed to dynamic partial melting beginning at 80 kilometers with a melt porosity of 0.2 percent or more. This result requires that melting beneath ridges occurs in a wide region and that the magma rises to the surface at a velocity of at least 0.9 meter ...

Thorium vs. Uranium
Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of Earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra. …

Thorium
Thorium (Th) is a radioactive metallic element that, until the 1950's, was known only by chemists and physicists. It is not abundant, but major supplies are in sands rich in monazite. Commercially, monazite is recovered as a by-product of the processing of titanium-bearing heavy-mineral sands.
