Sediment dating isotope techniques
We are preparing detectors and kilogram-scale sample preparation techniques for such a study of Puget Sound sediments. For example, if you began with 1 gram of carbon-14, after 5,730 years you would be left with 0.50 g and only 0.25 g after 11,460 years.The reason this age may not be a true age—even though it is commonly called an absolute age—is that it is based on several crucial assumptions.When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating.
However, there are many methods that can be used to determine the age of the earth or other objects.
Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.
