Rocks radiometric dating


The rise of science produced a major change in attitude.In the pre-scientific world view the issue of the age of the Earth was a theological question.In the 1700's belief in a 6000 year old Earth crumbled.Attempts to calculate the age of the Earth from physical considerations yielded estimates that ranged from 75,000 years (Buffon, 1774) to several billion years (de Maillet, Buffon).The account in Genesis is replete with miracles that do not stand up under rational analysis.This did not matter; the theological perspective did not require physical rationalization.These cosmogonies were part of the new emphasis of science in seeking rational explanations of the features of the world. This period was marked by a great deal of field geology rather than grand cosmogonies.It became clear that there had been significant changes in the Earth's topography over time and that these changes could neither be accounted for by natural processes operating during the brief nor by the postulated Noachian flood.

If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.

Notable observations included: ran from about 1780-1850.

    Radiometric dating uses the decay of isotopes of elements present in minerals as a measure of the age of the rock to do this, the rate of decay must be known, the proportion of different isotopes present when the mineral formed has to be assumed, and the proportions of different isotopes present today must be measured.…

    Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them. It has become increasingly clear that these.…

    Jun 28, 2006. These were once molten lavas that were successively erupted onto the earth's surface through volcanic vents and fissures and flowed over already deposited layers of siltstones. They quickly hardened into the dense, black rock called basalt Figure 3. Further thick sediment layers were soon deposited on.…

    Mar 30, 2017. I am by no means an expert in the many radiometric means of dating rock, but one of the systems often used and the one I believe your teacher was speaking of is potassium-argon dating. Rocks with potassium content will contain some primordial level of radioactive K-40 at the time of their formation.…
