Define stratigraphic dating
When an archaeological site is excavated the sides of the unexcavated baulk reveals layering of subsequent settlements and activity.
Stratigraphic excavation is the recording and study of these different strata as they are removed from the area.
The underlying principle of stratigraphic analysis in archaeology is that of superposition.
This term means that older artefacts are usually found below younger items.
The shape and style of an artefact changes through time although its function may remain the same.
The changing styles of pottery, glass, stoneware, and metal objects provide archaeology analysts with known progressive sequences.
Simply assuming that an artefact is older because it was found at a lower depth in the record is only subjective science.
Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries.At the moment of death the C14 begins to decay at a rate that scientists already know from other experiments.The missing amount can then determine how long it took to be lost and therefore date the object to a precise period.It's just a bit frustrating when you can't get an absolute conclusion, and many differing opinions. I have a gold ring which I believe is ancient but also important! The way it's constructed, the way the internal sides of the rings gold are melted with faults that look like bits of silver And the slightly differing colours, the hand carved gem and its,inscription!
