Relative dating with stratigraphy is based on the principle of dating agencies hampshire area
We can also see that if the fill of cut 5 – the wall 2, backfill 3 and trample 12 — are not removed entirely during excavation because of "undercutting", non-residual artifacts from these later "higher" contexts 2, 3 and 12 could contaminate the excavation of earlier contexts such as 9 and 10 and give false dating information.
Stratigraphy is the study of rock layers and layering.
These artifacts are referred to as "residual" or "residual finds".
It is crucial that dating a context is based on the latest dating evidence drawn from the context.
For example, the date of formation of a context which is totally sealed between two datable layers will fall between the dates of the two layers sealing it.
Stratigraphic relationships are the relationships created between contexts in time, representing the chronological order in which they were created.
