Radiometric dating services
The Stable Isotope Laboratory offers the possibility to analyse the composition of stable isotopes in carbonates (C in dissolved inorganic carbon).Due to the fact that during physicochemical processes like evaporation the composition of stable isotopes changes, their composition can be used to reconstruct these processes or the environmental conditions in general. This lesson is highly simplified, and the powerpoint describes everything the student will need to know for the activity.The Public Broadcasting Service (PBS) recently ran the story “1.8 million-year-old skull may revise understanding of human evolution.” Since the skull was unearthed in a medieval ninth century A. village in the former Soviet Republic of Georgia known as Dmanisi, the obvious question centers on the validity of the million year radiometric dating of the skull found within the same geological stratum as the medieval ninth century A. Without question, the theory of evolution from a single cell to a sophisticated carnivore demands millions and billions of years−not thousands of years.
This lesson introduces absolute dating and a few ways in which scientists accomplish it.Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.SAN FRANCISCO, March 23, 2010 — Scientists today described development of a new method to determine the age of ancient mummies, old artwork, and other relics without causing damage to these treasures of global cultural heritage.In theory, it could even be used to date the Shroud of Turin.” Rowe explained that the new method is a form of radiocarbon dating, the archaeologist’s standard tool to estimate the age of an object by measuring its content of naturally-occurring radioactive carbon.A professor emeritus at Texas A&M University College Station, Rowe teaches at a branch of the university in Qatar.
