Sedimentary rocks are made of tiny particles that are transported by natural agents like wind and water and laid down in different environments, forming one layer after another. The radiocarbon date for this canoe tells us it is between and years old. Understanding the ages of related fossil species helps scientists piece together the evolutionary history of a group of organisms. The Geologic Time Scale , 2-volume set. However, care is needed as some samples have fission tracks reset during bushfires, giving far too young ages. The uranium-lead dating method involves measuring the ratio of uranium to lead in a sample. However, there is a limited range in Sm-Nd isotopes in many igneous rocks, although metamorphic rocks that contain the mineral garnet are useful as this mineral has a large range in Sm-Nd isotopes.
