Examples are granites (formed by cooling under the ground) and basalts (formed by cooling of lava flows at the earth’s surface).

Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.Reading: Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (), a radioactive isotope of carbon.Diamonds are made in nature by super heating and compressing carbon over a long period of time.They then did carbon dating on the bone and it was considered 1000’s of years old.Their opinion is then that the age of fossils could be wrong as over time heat and pressure must alter the carbon state of all bones, organic matter and more.This is done by chemical analyses in specially equipped laboratories with sophisticated instruments capable of very good accuracy and precision.So, in general, few people quarrel with the resulting chemical analyses.Fossils, however, form in sedimentary rock — sediment quickly covers a dinosaur’s body, and the sediment and the bones gradually turn into rock.But this sediment doesn’t typically include the necessary isotopes in measurable amounts.Even though there are thousands of diamonds in storage ready for consumers, scientist have worked on creating artificial diamonds.These days we can now produce man made diamonds in large presses and extensive heat along with some chemistry tricks.
