By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them.While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.5 billion years old.Each of them typically exists in igneous rock, or rock made from cooled magma.



Graphic record for these deposits also supports the paleomagnetic interpretation e.g. Cuenca-Bescós et al. 1999; García and Arsuaga. 1999, as well as absolute dating including combined Uranium- series/Electron Spin Resonance ESR on fossil teeth Falguères et al. 1999 and thermoluminescence TL Berger et al.… continue reading »
