Chronological dating, or simply dating, is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology.This protocol was applied to several monazite standards to determine inter-spectrometer variability, and spectrometer reproducibility from session to session.This content is available through Read Online (Free) program, which relies on page scans.This usually requires what is commonly known as a "dating method".Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age.For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon-14, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.
An analytical protocol is presented that incorporates these results.
Analyses of Pb-free phosphates, silicates, and oxides are used to measure spectral interferences with the Pb M peak and background positions.
Backgrounds were modeled using both linear and exponential fits.
The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.
