Pb 210 dating method,

Geological Society of America, Special Paper5469— That is to say, the amount of each such element present is constant and the number that form per unit time is identical to the number that decay per unit time. The method has been applied to the ores of uranium. In this case, thorium in seawater, produced principally by the decay of uranium, is deposited preferentially in the sediment without the uranium parent. Environmental Geology2878— Email address.
