Question
Chapter 29, Problem 5TE
To determine
The isotopes preferred in dating sediments or organic material from the Pleistocene.
Expert Solution & Answer
Answer to Problem 5TE
The isotopes preferred in dating sediments or organic material from the Pleistocene is a combination of radioactive Uranium-238 of mineral content of sediments along with relative dating techniques.
Explanation of Solution
Radiometric dating is the process by which the concentrations of radioactive elements in rock structures are used to determine the age of the rock. The number of decayed atoms corresponds to how long the rock has been there, and it can be found out by knowing the half-life of the radioactive isotope. Carbon-14 is useful for determining the age of events that took place within
Conclusion:
Therefore, the isotopes preferred in dating sediments or organic material from the Pleistocene is a combination of radioactive Uranium-238 of mineral content of sediments along with relative dating techniques.
