Archaeological carbon dating

These curves indicate the changes in Carbon-14 throughout the years and modifies the end result of the tests to reflect that.Though the calibrated date is more precise, many scholars still use the uncalibrated date in order to keep chronologies consistent in academic communities.It is an essential technology that is heavily involved in archaeology and should be explored in greater depth.Radiocarbon dating uses the naturally occurring isotope Carbon-14 to approximate the age of organic materials. Often, archaeologists use graves and plant remains to date sites.Also, archaeologists cannot use their hands to touch the samples or smoke near them.They risk seriously altering the result of the test.Both organic or inorganic materials at the Earth's surface and in the oceans form in equilibrium with atmospheric carbon-14.This makes it an important tool for the understanding of processes during the time-scale of modern humans, from the last glacial-interglacial transition, to recent archaeological studies of art works.

As the lecture detailed, it is only accurate from about 62,000 years ago to 1,200 A. There is a sizable amount of time before and after that period that cannot be investigated using this method.

We present an overview of the technique, its advantages, assumptions and limitations. Radiocarbon has been applied to dating many historical artifacts and archaeological applications. PY - 2014Y1 - 2014N2 - Radiocarbon dating is an important tool for the determination of the age of many samples and covers the time period of approximately the last 50,000 years.

Some specific examples including dating of famous artifacts of artistic, religious and scientific interest are discussed. We can use radiocarbon dating to estimate the age of a wide variety of carbon-containing materials.

This is because radiocarbon dating gives the date when the tree ceased its intake of Carbon-14—not when it was being used for weapons and other instruments!

Since trees can have a lifespan of hundreds of years, its date of death might not even be relatively close to the date the archaeologists are looking for.
