Radiometric dating of meteorites from another solar system
How radiometric dating works in general radioactive elements decay gradually into other elements the original element is called the parent and the result of.
Isochron dating by chris stassen the article is well illustrated and well written there is an introduction to the generic problem of radiometric dating but this article concentrates on one well established method called the isochron method.
The age of the earth is 454 177 005 billion years 454 215 10 9 years 177 1 this age may represent the age of the earths accretion of core formation or of the material from which the earth formed this dating is based on evidence from radiometric agedating of meteorite material and is consistent with the radiometric ages of the oldestknown terrestrial and lunar samples.
meteorites have also been dated by the smnd isochron method jacobsen and wasserburg for example showed that 10 chondrites and the achondrite juvinas all fall on an isochron of 460 billion yearsthe results of radiometric dating on meteorites clearly indicate that these objects formed about 46 billion years ago.
The generally accepted age for the earth and the rest of the solar system is about 455 billion years plus or minus about 1 this value is derived from several.
Abstract using a figure published in 1960 of 14300000 tons per year as the meteoritic dust influx rate to the earth creationists have argued that the thin dust layer on the moons surface indicates that the moon and therefore the earth and solar system are young.
dating principles of isotopic dating all absolute isotopic ages are based on radioactive decay a process whereby a specific atom or isotope is converted into another specific atom or isotope at a constant and known rate most elements exist in different atomic forms that are identical in their chemical properties but differ in the number of neutral particlesie neutronsin the nucleus.
