About me:
Potassium Argon dating. Whenever the worldview of evolution is questioned, this topic always comes up. Let me first explain how carbon dating works and then show you the assumptions it is based on. Radiation from the sun strikes the radiocarbon dating and potassium-argon dating of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon This radioactive carbon 14 slowly decays back into normal, stable nitrogen.

Choosing the best method for radiocarbon dating depends on the quantity of available sample or, in radiocarbon dating and potassium-argon dating case of expensive materials, how much of it you can afford to be destroyed. AMS dating, for example, involves burning a sample to convert it to graphite. AMS dating is an advanced method compared to radiometric dating using liquid scintillation counters LSC. Fees for AMS analyses are higher. Samples submitted for radiometric dating will be reported as RadiometricPLUS, which combines large sample handling techniques with particle detection. This service is less expensive than AMS dating.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word "absolute" implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics.

Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials. Geologists have used this method to date rocks as much as 4 billion years old. It is based on the fact that some of the radioactive isotope of Potassium, Potassium K ,decays to the gas Argon as Argon Ar By comparing the proportion of K to Ar in a sample of radiocarbon dating and potassium-argon dating rock, and knowing the decay rate of K, the date that the rock formed can be determined.
