What is the difference between relative and radiometric absolute dating Free adult web chats
You will find the essential part of the answer to your question in this "Socratic" link: What remains to be seen is: when should you use the one rather than the other.
Relative dating is useful during field work to measure, for instance, the throw of a fault, or to re-instate the missing part of a stratigraphic sequence.
In micro paleontological analysis, you may not need the general view if all you are trying to establish is which of two foraminifera is the older.
However, if you are mapping an area, if you want to fit your local intuition into the regional picture, you could not do without absolute dating.
Faunal deposits include remains and fossils of dead animals.
Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.
Radiometric dating: This technique solely depends on the traces of radioactive isotopes found in fossils.The changes in this content help determine the relative age of these fossils.Dendrochronology: Each tree has growth rings in its trunk.This technique dates the time period during which these rings were formed.Thermoluminescence: It determines the period during which certain object was last subjected to heat.
