By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site. Sometimes sedimentary rocks are disturbed by events, such as fault movements, that cut across layers after the rocks were deposited. Each isotope is identified by its atomic masswhich is the number of protons plus neutrons. A technique used to date materials such as rocks or carbon. For most radioactive nuclides, the half-life depends solely on nuclear properties and is essentially a constant.

Dating Fossils – How Are Fossils Dated?

The abundances of parent and daughter isotopes in a sample can be measured and used to determine their age. Radiocarbon dating is generally limited to dating samples no more than 50, years old, as samples older than that have insufficient 14 C to be measurable. Brent The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age. A subatomic particle found in the atomic nucleus with a neutral charge and a mass approximately equal to a proton optical stimulating luminescence:
