Pollen dating archaeology
Further, he proposed that wherever uncontorted layers were exposed, the bottom layer was deposited first and was, therefore, the oldest layer exposed; each succeeding layer, up to the topmost one, was progressively younger.
The Major Divisions of Geologic Time are shown here, arranged in chronological order with the oldest division at the bottom, the youngest at the top. Specifically, stratigraphy refers to the application of the Law of Superposition to soil and geological strata containing archaeological materials in order to determine the relative ages of layers.
Two or more excavated objects that are thought to be related are said to be in association, e.g.
artefacts discovered in close proximity within the same context, or architectural features thought to have been standing at the same time.
The depth of the sample corresponds roughly to how old it is, and therefore the vertical axis may also contain an estimate of its absolute age.
Used to visualise the environmental history of the place where the sample was taken.
A few examples of such lies are presented at the very bottom of this page.Pollen extracted from ocean and wetland sediments cored from the eastern Canadian Margin, James Bay region, and Atlantic provinces of Canada have been radiocarbon dated and results are reported here.Pollen dates from ocean sediments were compared with marine carbonate (mollusk shells or foraminifera) dates from the same core levels, dates for which validity was assessed via correlations with other cores, and for which reworking has been excluded.Many of these links also appear where appropriate below.James Hutton and William Smith advanced the concept of geologic time and strengthened the belief in an ancient world.
