WebThe calculated age is the age from which the rock or mineral stabilized. The interpretation of the age date also depends somewhat on the kind of rock being analyzed. For example, age dates from volcanic rocks that cooled quickly can give an age that is very close to the age of the eruption of the volcanic flow. Since it takes plutonic rocks ... Samarium has five naturally occurring isotopes, and neodymium has seven. The two elements are joined in a parent–daughter relationship by the alpha decay of parent Sm to radiogenic daughter Nd with a half-life of 1.06×10 years and by the alpha decay of Sm (an almost-extinct radionuclide with a half-life of 1.03(5)×10 years ) to produce Nd.
