Topic: Dating methods in Archaeology. Are they accurate.

Another absolute dating method is thermoluminescence, which dates the last time an item was heated. It is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between 300 to 10,000 years old.

Introduction to Geology - Geology Cafe.com Chemical Bonds Molecular compounds are held together on an atomic level by chemical bonds. Three types of chemical bonds include ionic bonds, metallic bonds, and covalent bonds.The types of chemical bond influence the physical properties of the molecular compounds they form.

Radioactive decay - Wikipedia Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion.

Carbon-14, Radiometric Dating - CSI Carbon dating is used to determine the age of biological artifacts up to 50,000 years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).

What is Carbon-14 (14C) Dating? Carbon Dating Definition Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

8 Re: Radioactive isotope used for geological dating

Radiometric dating - Wikipedia Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
