Age of deposition should not be confused with the date of material enclosed in deposit.Cross dating involves comparing similar artifacts from similar sites that may be of similar age.
The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.
Reliability of age: reliability of technique and association How to know full or absolute age in years before present of different parts of the sequence. Assignment of an age to a physical remain based on direct analysis of that physical remain.
Reliability of age = reliability of technique Two artifacts are buried at the same time within the same archaeo.
According to the laws of superposition, a strategic layer that is higher has been deposited more recently.
The oldest strata are at the bottom of the sequence.
