Tephrochronology is a method for geochemical correlation of unknown volcanic ash (tephra) to geochemically fingerprinted, dated tephra.Tephra is also often used as a dating tool in archaeology, since the dates of some eruptions are well-established.The textbooks speak of the radiometric dating techniques, and the dates themselves, as factual information.Far from being data, these dates are actually interpretations of the data.A sequence of paleomagnetic poles (usually called virtual geomagnetic poles), which are already well defined in age, constitutes an apparent polar wander path (APWP).

For paleomagnetic dating, it is suggested to use the APWP in order to date a pole obtained from rocks or sediments of unknown age by linking the paleopole to the nearest point on the APWP.Marker horizons are stratigraphic units of the same age and of such distinctive composition and appearance, that despite their presence in different geographic sites, there is certainty about their age-equivalence.Fossil faunal and floral assemblages, both marine and terrestrial, make for distinctive marker horizons.For since the fathers fell asleep, all things continue as they were from the beginning of creation.” For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, by which the world that then existed perished, being flooded with water.Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.
