Rb-Sr is another method that is difficult to interpret when there is evidence of thermal events.It has a half-life of 1.3 billion years, meaning that over a period of 1.3 Ga one-half of the Figure 8.14 The decay of 40K over time.Each half-life is 1.3 billion years, so after 3.9 billion years (three half-lives) 12.5% of the original 40K will remain.C) can be applied to many geological materials, including sediments and sedimentary rocks, but the materials in question must be younger than 60 ka.Fragments of wood incorporated into young sediments are good candidates for carbon dating, and this technique has been used widely in studies involving late Pleistocene glaciers and glacial sediments.

If we dated a number of individual grains in the sedimentary rock, we would likely get a range of different dates, all older than the age of the rock.
