Isochron dating is a common technique of radiometric dating and is applied to date certain events, such as crystallization , metamorphism , shock events, and differentiation of precursor melts, in the history of rocks. Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating ; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks meteorites. The advantage of isochron dating as compared to simple radiometric dating techniques is that no assumptions are needed about the initial amount of the daughter nuclide in the radioactive decay sequence. Indeed, the initial amount of the daughter product can be determined using isochron dating. This technique can be applied if the daughter element has at least one stable isotope other than the daughter isotope into which the parent nuclide decays. All forms of isochron dating assume that the source of the rock or rocks contained unknown amounts of both radiogenic and non-radiogenic isotopes of the daughter element, along with some amount of the parent nuclide. Thus, at the moment of crystallization, the ratio of the concentration of the radiogenic isotope of the daughter element to that of the non-radiogenic isotope is some value independent of the concentration of the parent. As time goes on, some amount of the parent decays into the radiogenic isotope of the daughter, increasing the ratio of the concentration of the radiogenic isotope to that of the daughter. The greater the initial concentration of the parent, the greater the concentration of the radiogenic daughter isotope will be at some particular time. Thus, the ratio of the daughter to non-radiogenic isotope will become larger with time, while the ratio of parent to daughter will become smaller. An isochron diagram will only give a valid age if all samples are cogenetic , which means they have the same initial isotopic composition that is, the rocks are from the same unit, the minerals are from the same rock, etc. The mathematical expression from which the isochron is derived is [4] [5]. Because the isotopes are measured by mass spectrometry , ratios are used instead of absolute concentrations since mass spectrometers usually measure the former rather than the latter. See the section on isotope ratio mass spectrometry.

Move the slider and watch the slope of the isochron change over time. You can also type numbers directly into the text box displaying the slope. Press the return key to activate any typed-in change.

Create process flow diagrams that illustrate the use of each of the following strategies: Useful for understanding biotic diversity through time and large scale patterns of evolution. Invertebrates diversify into many new types. Indeed some regions of the genome are more likely to sustain mutations than others and various physical causes.
