Numerical dating

Contrary to this, the absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.The relative dating is the technique to ascertain the age of the artifacts, rocks or even sites while comparing one from the other.The radiometric dating is another crucial technique through which the exact age can be obtained.

As the word relative tells that defining the object with respect to the other object, it will be pertinent to mention here that actual numerical dates of the rocks or sites are not known in this type of dating.Students should come up with the intended ages for their zircons and should be able to evaluate whether or not their relative age hypotheses are consistent with the numerical dates. Over the past few years, OSL and TCN datings of glacial material from High Asia have come into fashion.Sample dating is done by counting beads that represent 235U and 207Pb atoms in a zircon.Students should be able to read x-y plots and divide two numbers.
