Sixteen years after his discovery, he published a geological map of England showing the rocks of different geologic time eras. The numerical value of relative dating in Chaldean Numerology is: The numerical value of relative dating in Pythagorean Numerology is: Relative dating Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age.

And fossils and archaeological objects which come from a deeper stratigraphical layer are supposed to be older. Likewise, fossils and archaeological objects which come from a more superficial stratigraphical layer are supposed to be younger.

This was roughly the dating method used by scientists in the early days of palaeontology and archaeology, before the emergence of absolute radiometric dating methods radiocarbon, potassium-argon, thermoluminescence, OSL, etc. The relative dating method is still helpful, since basically it gives reasonably good results.
Geologic Age:
And not every fossil or archaeological object can be dated, since radiometric dating methods are mostly rather costly, and the financial means of most research teams are limited. But one must be careful by interpreting the results of excavations since stratigraphical layers may present abnormalities.
In some cases inversion of stratigraphical layers may occur, with older layers being on top of younger ones.
And in some cases older objects may be moved out of their original context and get mixed with younger objects, in a stratigraphically younger layer. This is the reason why most palaeontologists and archaeologists collaborate with geologists, in order to explain the processes which were at the origin of the sedimentation of the layers.
Relative dating with its pros and cons is very well described in this Wikipedia article: Relative dating - Wikipedia. How close is this relative? It is unlawful to date very close primary relatives such as a sibling or parent.

If the relative is old enough to consider classifying as a fossil, surely there is less possibility in any resulting offspring, but adding a great age difference to the mix can not contribute to long term happiness either. Perhaps you might give greater thought to travelling any further along this road….

Relative dating occurs when a rock layer sandwiched between, above or below, other layers with known dates, either due to those layers have minerals that can be radiometrically dated or because those layers contain other marker fossils with known dates. Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!
