Relative or absolute dating
Fluorine dating: Bones from fossils absorb fluorine from the groundwater.The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.
Provide an idea of the sequence in which events have occurred.2.The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.However, not all fossils or remains contain such elements.To find their age, two major geological dating methods are used.These are called relative and absolute dating techniques.Thermoluminescence: It determines the period during which certain object was last subjected to heat.
It is based on the concept that heated objects absorb light, and emit electrons. A Venn diagram depicts both dating methods as two individual sets.
Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.
Faunal deposits include remains and fossils of dead animals.
Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.
These remains are subjected to dating techniques in order to predict their ages and trace their history.
Stratigraphy: The oldest dating method which studies the successive placement of layers.
