Overview of Methods Superposition Stratigraphy Dendrochronology Radiocarbon C14 Radiometric Dating Methods Obsidian Hydration Dating Paleomagnetic/Archaeomagnetic Luminescence Dating Methods Amino Acid Racemization Fission-track Dating Ice Cores Varves Pollens Corals Cation Ratio Fluorine Dating Patination Oxidizable Carbon Ratio Electron Spin Resonance Cosmic-ray Exposure Dating This is an excellent overview of dating methodologies, and is a chapter in a textbook on Archaeology.

You may find it useful for the clear definitions, and for excellent links on a variety of topic.

Kelvin knew that the Earth gets hotter with increasing depth (the geothermal gradient), and took this observation as evidence that the Earth is cooling off. Chamberlain challenged Kelvins assumption that the earth started as a molten body.

He believed the Earth started off as a molten mass and subsequently transformed to a hot solid mass during cooling. Instead, Chamberlain proposed a model of cold accretion for the Earth.

Kelvin argued that this was physically impossible (the concept is akin to a perpetual motion machine).For each dating or chronological method there is a link in the box at right to take you to that section of this page.There, you will find a brief description of the method, plus links to take you to other webpages with more extensive information.The quantitative approach is admirable, but Buffon's assumptions are flawed. Silicate minerals have lower heat conductivity than steels and are better insulators leading to slower cooling rates.Second, the calculations did not incorporate the heating effects of radioactive decay.
