|
Seriation
|
The artifical ordering of artifacts 'into seris" and based on shared similarities. artifacts that are similar are close in time.Useful when there is no info on the context.
|
|
|
Stylistic Seriation
|
Seris are organized by using the "style" of the artifact.
|
|
|
Frequency Seriations
|
Based on the changes in the proportion of artifacts
|
|
|
Sequence Comparison
|
We estimate the age of the artifact by comparison
|
|
|
Geological and Geochemical Age determination
|
Similar to Stratigraphy. The age of the cultural materials is assessed by association with old geological deposits
|
|
|
Varve Accumulation
|
Useful for areas with ancient glacial lakes. There is a constant accumulation of varves (layers of outwash) in glacial lakes. produced by retarting ice sheets
|
|
|
Obsidian hydration
|
Based on the obsidian's absorption of water at a constant rate. the thickness of the hydration layer serves to calculate the period in which the artifact was made.
|
|
|
Faunal and floral deterimination
|
Diagnostic species are used to date specific time periods. provides info in the nature of the enviroment.
|
|
|
Dendrochronology
|
The number of rings in the tree determine the age of the tree
|
|
|
Bone age determination
|
Bone remains from the same context will lose organic components. two bone remains from different context will have different amounts of flurine and uranium
|
|
|
radiocarbon determination
|
C14 decays into N14 at a constant rate. By measuring the amount of C14 still left we can calculate when the organisim died.
