What is the definition of relative dating
Associations between objects are the basis for as well as in interpretation -- cultural connections, original function, etc.
Pottery and flint tools associated in a closed context would be grounds for linking them into an assemblage, possibly making the full of a group available.
Another problem is that there may be gaps in the sequences of available timber, so that the chronology 'floats', or is not tied in to a calendrical date or living trees: it can only be used for .
Also, the tree-ring key can only go back a certain distance into the past, since the availability of sufficient amounts of timber to construct a sequence obviously decreases.
A relative date is a date which can be said to be earlier than, later than, or contemporary with an event but which (unlike an absolute date) cannot be measured in calendar years.
Objects are said to be in association with each other when they are found together in a context which suggests simultaneous deposition.The central rings of this older tree may then be compared with the outer rings or a yet older tree, and so on until the dates reach back into prehistory.Problems that arise are when climatic variation and suitable trees (sensitive trees react to climatic changes, complacent trees do not) are not be present to produce any significant and recognizable pattern of variation in the rings.The methods have varying applications, accuracy, range, and cost.Many new techniques are being developed and tested.
