Absolute time radiometric dating: the source of the dates on the geologic time scale radiometric dating actually a simple technique only two measurements are needed. Earth sciences - radiometric dating: a radiometric dating technique that measures the ratio of the rare earth elements neodymium and samarium present in a rock.

New ways of dating rocks are supposed to be able to give ages in the billions of years these are the radiometric dating methods each of these methods is based upon the decay rate of. Radiometric dating is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope. Radiometric dating is a means of determining the age of a mineral specimen by determining the relative amounts present of certain radioactive elements by age we mean the elapsed time. Geologists use radiometric dating methods to determine the age of strata and fossils are they always accurate does an evolutionary bias affect the dating.

Creation 101: radiometric dating and the age of the earth by dr lisle | oct 27, the measured ratio of certain radioactive elements is used as a proxy for age. The assumptions needed for radiometric dating to be useful and reasonably accurate are: that no material has been added or lost from the material being dated. Radiometric dating both techniques rely on the properties of radioactive isotopes, which are unstable elements that decay into stable ones over time. Isotopes commonly used for radiometric dating isotopes: half-life (years) effective dating range (years) dating sample: key fission product: lutetium-176: hafnium-176.
