Since uranium is water-soluble and thorium is not, thorium atoms will accumulate in precipitated carbonate (modulated by their decay rate) whereas the concentration of uranium remains fixed. The technique can be utilized to determine carbonate ages https://hookupranker.com/wapa-review/ to some 500 ka BP.
